If your child receives a PSLE Score of 25 with Foundation Science grade A, your family can choose either Posting Group 1 or Posting Group 2 for Secondary 1 in Singapore. Foundation Science A contributes the equivalent of AL6 to the PSLE aggregate, but it is a Foundation grade and should not be described as identical to Standard Science AL6. Under Full Subject-Based Banding, a pupil entering PG1 with Foundation Science A can be eligible for G2 Science while most subjects start at G1; a pupil entering PG2 ordinarily starts most subjects, including Science, at G2. Parents should compare the child’s understanding of observations, experiments, diagrams and scientific explanations with their readiness for the rest of the secondary curriculum before choosing one route and six suitable schools.

For the 2026 PSLE cohort entering Secondary 1 in 2027, the published MOE SchoolFinder score ranges show the 2025 PSLE cohort’s 2026 entry outcomes. They are not advance 2027 cut-offs. At a score of 25, a PG2 school with last year’s cut-off of 25 was at the historical boundary; a PG2 cut-off of 24 was a reach. The same school can show a PG1 cut-off of 28, 29 or 30*, giving a very different numerical comparison but also a different usual starting load. Families should examine actual Science teaching, English and Mathematics support, CCAs, travel, the child’s comfort and the appropriate school admission route—not just select whichever previous cut-off looks most favourable.

Quick parent summary
• PSLE Score 25: an official choice between Posting Group 1 and Posting Group 2.
• Foundation Science A: maps to equivalent AL6 for PSLE score calculation; this is not Standard Science AL6.
• Under PG1, Foundation Science A meets the usual subject-grade criterion for a G2 Science offer, subject to school arrangements.
• Under PG2, Science generally begins at G2; Foundation A by itself does not satisfy the Standard AL5 criterion for G3 Science.
• One chosen Posting Group must apply to all six ordinary school preferences.
• Use the correct historical PG1 or PG2 score range, and understand any 30* vacancy notation.
• Compare practical Science learning, English/Maths foundations, lab safety, location and pupil wellbeing.

What Foundation Science A does and does not mean

Foundation Science is a different PSLE assessment level from Standard Science. A Foundation grade of A, B or C is mapped to an equivalent AL6, AL7 or AL8 respectively when computing the four-subject PSLE total. The mapping supports posting and curriculum planning; it does not mean that the child sat the Standard Science paper or demonstrated exactly the same knowledge as someone who received Standard AL6.

For example, a pupil could receive Foundation Science A, contributing AL6, alongside English AL6, Mathematics AL7 and Mother Tongue AL6, making a total of 25. A different child might take Standard Science and earn AL6, with other grades producing the same total. Both could have the same PG1/PG2 posting choice, but their Science classroom histories would differ.

The distinction matters because subject-level eligibility rules refer explicitly to Standard and Foundation grades. Foundation A at a PG1 starting level makes an eligible G2 Science offer possible. It does not satisfy the Standard AL5-or-better criterion required for a PG2 pupil to be offered G3 Science on the basis of PSLE performance.

A parent’s school-choice spreadsheet should preserve the original Foundation A result next to the equivalent contribution. If the child later receives a subject-level offer from a secondary school, use that official offer rather than interpreting the result independently or buying a G3 textbook because the family hopes for the highest level.

The two routes at PSLE 25: a clear comparison

Question	Posting Group 1	Posting Group 2
Available with score 25?	Yes	Yes
Usual starting level of most subjects	G1	G2
Foundation Science A at the start	May be offered G2 Science under the relevant criteria	Science ordinarily starts at G2
Is Foundation A enough for G3 Science?	No, not under the Standard AL5 rule	No; PG2-to-G3 ordinarily requires Standard AL5 or better
Historical school range to compare	PG1 only	PG2 only
Main educational choice	Would G1 generally, with Science at G2 where appropriate, help the child learn?	Is the wider G2 starting curriculum suitable across subjects?

These routes are both legitimate parts of Singapore’s current education system. The question is not which is more impressive to friends. The question is what the child needs in order to learn steadily, enjoy school and build the foundations required for future subjects and qualifications.

A child who performed well in Foundation Science might be ready to investigate the more demanding Science curriculum, yet still need additional support with English comprehension or Mathematics. PG1 with eligible G2 Science can offer a coherent beginning for some pupils. Another pupil might be broadly ready for G2 across most subjects, making PG2 suitable.

The choice changes the admissions comparison as well as the usual subject demand. A school with PG2 cut-off 25 and PG1 cut-off 28 has not made two offers to the same child. It had separate historical posting results for two groups. The family must decide the appropriate route before constructing the final six-choice list.

Once the school is assigned, eligible more demanding subject offers may require a response through the school’s prescribed system. Parents should check the letter and deadline before making assumptions about the timetable, textbooks or what happens if an offer is declined.

These figures are 2025 PSLE non-affiliated historical cut-offs for pupils entering Secondary 1 in 2026. They are not forecasts or guarantees for 2027. Current school availability and details must be verified with MOE SchoolFinder. Schools below differ greatly in location; select those relevant to the family rather than copy every name.

At score 25 through PG2, the pupil is at the historical endpoint of schools whose cut-offs were 25. A school that ended at 24 or 23 is a historical reach. Because 25 is the top of the usual PG2 score range, there may be no PG2 school with a prior cut-off numerically above 25 to provide a positive margin. It is important to acknowledge this instead of inventing reassuring numbers.

Through PG1, many schools showed previous endpoints of 27, 28, 29 or 30. This gives a score-25 pupil larger historical numerical margins, but the general starting curriculum is G1 rather than G2. A strong educational decision must consider that difference and what G2 Science, if offered, would contribute.

Where a school shows 30*, the asterisk means the school had vacancies after the previous posting exercise, and the reference value is written as 30. It does not necessarily mean the last pupil posted actually scored 30; it does not guarantee a place next year. Keep that notation when preparing a parent worksheet.

A lower previous cut-off does not prove the school has better Science teachers, laboratories or results for every pupil. The statistic is a record of past demand and allocation. Teaching quality, safety, programmes and fit must be researched separately through official school information and direct questions.

Why the child’s actual Science understanding matters more than the letter A alone

The Foundation Science grade gives useful information about progress within the Primary 6 Foundation curriculum. It does not reveal which Science concepts the pupil can apply independently in unfamiliar situations. Some children understand the life cycles of plants well but struggle with forces or electrical circuits. Others enjoy hands-on activities but need support with written scientific explanations.

Ask the primary-school teacher what the child does when faced with an unfamiliar question. Do they read carefully, identify what is being investigated, use evidence from the diagram and write a complete explanation? Or do they remember a sentence without understanding when it applies? The answer can guide the choice between an ordinary G1 Science start and eligible G2 Science.

The family should also distinguish difficulty with the scientific idea from difficulty expressing it in English. A child may understand that a plant needs light for photosynthesis but struggle to put the explanation into a clear sentence. Improved literacy can help, but teaching should also make the underlying concept explicit.

Confidence should not be measured by how quickly the pupil answers one practice question. A student who checks an experiment, notices an error and improves a conclusion may be displaying a valuable scientific habit. The best subject-level choice allows these skills to develop without constant fear of failure.

Scientific observation: seeing what actually happened

A good Science explanation begins with accurate observation. Parents can help by asking children to describe what changed before offering a theory. When a seed sprouts, how many days passed before the first shoot appeared? What colour and shape were the leaves? Was there a visible difference between two plants? These questions separate an observation from a conclusion.

A common mistake is to say ‘the plant was healthier’ without defining what was measured. Instead, the child could record its height or the number of new leaves and compare results. The data are simple, but the habit of describing evidence is transferable to more demanding Science.

Another mistake is to assume that an observed change proves only one cause. If two plants receive different amounts of water but also different light, the child cannot fairly attribute the result to water alone. Learning to notice this ambiguity is part of scientific reasoning. It helps pupils understand fair tests, variables and experimental limitations.

Families do not need a laboratory for every learning activity. Safe, ordinary observations can support careful thinking. Avoid hazardous substances, electrical equipment beyond normal safe use or experiments involving heat without appropriate adult supervision. School laboratory safety rules always take precedence in formal practical lessons.

Science questions: claim, evidence and explanation

A child preparing for G2 Science benefits from a simple structure: what do I think happened, what evidence supports it, and which scientific concept explains it? That sequence prevents answers that list memorised phrases but fail to address the question.

Suppose two identical metal objects are left in different places and their temperatures are compared. The claim might be that one warmed more quickly. The evidence would come from measured temperature changes over the same interval. The explanation should connect those measurements to the relevant heat-transfer conditions, without pretending that a measurement proves more than it does.

In a reading passage, students can underline the actual observations and identify information that is irrelevant to the conclusion. In a diagram, they can label what was controlled and what was measured. In a graph, they can describe the overall trend and notice unusual points rather than simply guess at the answer.

These are skills that need practice over time. A pupil who understands a task verbally may still need help writing it. Parents can ask the child to explain aloud first and then turn the reasoning into a few clear sentences. The goal is independent explanation, not copying the adult’s model answer word for word.

Measurement and numeracy inside lower-secondary Science

Secondary Science uses measurement, units, ratios, graphs and calculation. A child who is interested in Science but struggles with Mathematics may need explicit teaching of the numbers involved. This matters when choosing PG2 generally or an eligible G2 Science offer within PG1. Readiness for Science includes understanding what quantities mean.

For example, students may compare the mass of objects, the volume of a liquid, temperature changes or the time needed for a process. They need to record the correct unit, read the instrument carefully and judge whether a result is reasonable. A mistake in scale reading can make a scientifically sound idea produce an incorrect answer.

Parents can help through everyday measurement. Read a measuring jug together, compare the mass of groceries using a kitchen scale, or interpret a simple temperature chart. Ask the child how they know which measurement is larger and whether the units match. Do not begin with complex formulae before the quantities themselves make sense.

If a pupil is anxious about numbers, a supportive Science programme can use concrete objects and diagrams to strengthen confidence. Ask prospective schools how Science and Mathematics teachers work with students who need additional numerical foundations.

How G2 Science differs from simply doing more Foundation worksheets

A more demanding Science level is not just a larger number of exercises. It can involve greater conceptual depth, unfamiliar applications and more independent reasoning. A pupil needs to explain causes, interpret evidence and work with topics that build on earlier knowledge. The school can explain how the lower-secondary G2 syllabus is introduced and what foundations it assumes.

It may be appropriate to revisit Primary 6 ideas using better questions rather than repeat them mechanically. For instance, after identifying the parts of a plant, the learner might compare conditions affecting growth and consider whether the observations support the conclusion. This extends the concept while keeping the reasoning grounded in something visible.

Parents should ask what the receiving school does when a pupil is eligible for G2 Science but is unsure about one topic. Are teachers able to identify and repair gaps? Is bridging material available? How is feedback given? A pupil should know that moving to a more demanding level may involve mistakes and that seeking clarification is part of learning.

Where the pupil struggles substantially, the family can consult the school about the actual level and workload. There are school rules for subject-level adjustments; do not promise that any change will be automatic or available at any moment.

The case for PG1 with an eligible G2 Science subject

Imagine a child who understands practical Science but needs a slower pace with English and Mathematics. PG1 may provide a general starting timetable at G1 while allowing eligible G2 Science. That can create a more tailored experience when supported by the school’s timetable and teaching. The family should not treat the subject offer as guaranteed until it is confirmed.

The practical advantage may be time to strengthen reading and arithmetic without removing all challenge from a favoured subject. A pupil might enjoy explaining an experiment in G2 Science while continuing to build foundational English and numeracy. The correct combination can support both confidence and deeper learning.

Families should ask about actual class arrangements. Will the pupil attend Science with other students at G2 while remaining in a mixed form class for common curriculum activities? How is homework coordinated? Who helps when the pupil struggles with scientific vocabulary? These are reasonable questions that reveal the everyday experience.

A wider historical PG1 admission margin can be useful, but it should not be the only reason for the choice. The core question remains whether the usual G1 load plus a more demanding Science option matches the child’s readiness and interests.

The case for PG2 as the general starting route

Another pupil with score 25 and Foundation Science A may be ready for G2 across most subjects. Their schoolwork may show good independent reading, stable Mathematics and a willingness to attempt new concepts. PG2 could therefore provide an appropriate academic start. The family should examine the whole profile rather than assume the Science Foundation grade means the child needs G1 generally.

The admissions comparison is more demanding at this boundary. Many PG2 historical cut-offs ended at 25. The family should not claim that a school whose previous PG2 endpoint was 25 is certain, or that a school with previous PG2 24 is safe. If the family chooses PG2, it should discuss the historical range limitation and official guidance carefully.

At PG2, the child normally starts Science at G2. The Foundation Science A grade does not independently make the child eligible to jump to G3 Science from that starting level. The school’s current criteria for later progression can be investigated, but the family should not make promises based on an assumption that grades automatically map across assessment levels.

A child who starts at G2 and finds a topic difficult needs support, not condemnation. Effective learning involves asking questions, reviewing misconceptions and developing routines that can be maintained throughout the term.

A worked case: score 25, Foundation Science A and weaker Mathematics

Consider a fictional pupil with English AL6, Mathematics AL7, Foundation Science A contributing AL6, and Mother Tongue AL6. The PSLE total is 25. The child loves observing insects and learning about plants but struggles with fractions and multi-step mathematical problems. The family initially assumes choosing PG2 is the only way to support the child’s interest in Science.

They consult the primary-school teacher, who says the pupil understands common scientific ideas but needs more time with numeracy. The family investigates PG1 with an eligible G2 Science offer and compares it with the ordinary PG2 starting timetable. They check each route’s historical school ranges separately, noting that a school might have had PG2 25 but PG1 28.

At an open house, the pupil is excited by a design activity and asks questions about how an experiment works. The parents also ask how the school supports pupils who are doing Science at a higher level than Mathematics and whether the journey would be practical on a CCA day.

This fictional case does not mean all children with Foundation Science A should choose PG1. It illustrates a responsible process: analyse the actual skills, examine curriculum demand and then make a genuine school choice.

A second worked case: score 25 and balanced readiness

Another child with Foundation Science A and overall score 25 has relatively balanced grades and works independently in most subjects. The parents consider PG2 because the pupil seems ready for a G2 timetable across English, Mathematics, Science and Mother Tongue. They ask the school how the Foundation-to-secondary Science transition will be taught and what additional support is available.

The family notices several schools have past PG2 cut-offs of 25 and others of 24. They are careful not to call the old boundary a guarantee. They check school programmes, travel and the child’s comfort in the environment and rank a suitable list. If the pupil would feel more confident in PG1 with an individual Science stretch, the family is prepared to review its plan.

The child is not told that a higher numbered Posting Group is a reward or that a lower one is a defeat. Instead the adults explain the intended learning load and why it matches the pupil’s current strengths. That explanation can help the child begin school with a sense of ownership.

Once the posting is confirmed, the family reads the actual offer letter and organises materials for the correct subjects. They do not assume that an offer from another school’s previous intake applies automatically.

Questions to ask at a school open house about Science

• Does the school offer G2 Science to a PG1 entrant with Foundation Science grade A under the current criteria?
• What is the difference in topic depth, experimental reasoning and written explanations between G1 and G2 Science?
• How are students taught fair tests, variables, measurement and graph interpretation?
• What extra help is available when a child understands the scientific idea but struggles to write an explanation?
• How do teachers support pupils taking Science at a different level from English or Mathematics?
• Are the school’s Applied Learning Programme and Science-related activities available to ordinary pupils?
• What laboratory safety instruction do new Secondary 1 students receive?
• How can parents understand the process for reviewing subject-level choices later?
• What are the current school timetable, CCA commitments and transport arrangements?

Which school programmes are actually worth comparing?

Science-related programmes can include sustainable living, design thinking, technology, environmental education or practical problem solving. The programme title alone does not show what the child will do. Ask whether all Secondary 1 students participate, how teachers teach investigation skills and whether students receive feedback on their reasoning.

Kranji’s published design innovation for sustainable living is one example of a programme parents might investigate. Another school may focus on a different applied learning area. The right match depends on whether the child enjoys the activities and can take part meaningfully, not on which description sounds most fashionable.

CCAs also matter. Some pupils find science clubs, robotics or environmental activities appealing; others prefer sport, performing arts or a uniformed group. A good school gives room for the child to grow beyond the PSLE subjects. Ask whether places are limited and what a normal weekly commitment involves.

A short commute can be particularly useful when a pupil is building confidence with a more demanding subject. It gives time to complete homework carefully, rest and read. A longer journey can still be worthwhile for a genuinely special opportunity, but the family should understand the cost in daily life.

Building a six-choice list without mixing PG1 and PG2

The first step is deciding the suitable Posting Group after comparing the child’s whole learning profile. The ordinary S1 Internet System applies one chosen Posting Group across all six school preferences for pupils eligible for two groups. A family cannot use the PG1 cut-off for Kranji and the PG2 cut-off for Queensway in one final list as if those were independent routing decisions.

Make an initial list of schools that offer each group and are realistically accessible. Record the actual historical score range for the relevant group, school activities, transport and any admission conditions. Then decide which route offers a suitable academic beginning and shortlist six acceptable schools through that group.

MOE generally encourages two or three schools where the child’s score is numerically better than the previous cut-off. That is more straightforward through PG1 at score 25 than through PG2, whose upper score limit is 25. If a family chooses PG2, acknowledge the lack of a positive historical margin and seek appropriate school advice rather than inventing scores beyond the allowed range.

Rank the chosen six according to genuine preference. Among pupils with the same PSLE total competing for a final place, citizenship, choice order and computerised balloting are tie-breakers. It is not correct to put an unwanted school first simply because a rumour claims the choice order overrides the score.

Every school on the final list should be somewhere the child can imagine learning and belonging. A good list is not a spreadsheet exercise detached from everyday school life. The pupil’s voice, actual learning needs and family’s practical commitments matter.

What to do during the holiday: a realistic Science bridge

The period after PSLE can be used to rebuild curiosity and a few useful habits. A child with Foundation Science A does not need to read the entire G2 textbook before school begins. Instead, practise explaining simple observations accurately, reading basic tables and making conclusions supported by evidence.

Use safe everyday examples. Compare the amount of water in two containers, observe changes in a houseplant over several days or discuss why food needs appropriate storage. Ask what can actually be observed and what would require further testing. These questions develop scientific caution and reasoning.

Encourage the child to write down a short sequence: question, observation, explanation. If they find writing difficult, begin with an oral explanation and jointly construct a clear sentence before asking them to write independently. This develops Science and English together without turning the activity into another high-stakes test.

Also practise basic numeracy and school organisation. Reading a thermometer, understanding simple units and checking homework instructions are skills that support Science. The child should have time for sleep, physical activity and friendships; a balanced holiday helps the new school year start well.

The transition into secondary-level subjects and the SEC

The Singapore-Cambridge Secondary Education Certificate replaces the former separate N- and O-Level examination structure from 2027. Under Full Subject-Based Banding, students eventually take relevant subjects at G1, G2 or G3, and later post-secondary pathways depend on subject combinations, achieved results and the prevailing admission rules.

The Posting Group chosen at score 25 is a starting framework. It does not determine every future qualification or career. The pupil may develop particular interests and strengths during Secondary 1 and later years, with subject-level adjustments considered under school policies and MOE guidance.

Parents can ask the receiving school how G2 Science relates to later subject options and what the child would need to demonstrate to pursue a more demanding level at a later stage. Specific progression criteria should be obtained from the school; do not promise an automatic transfer or a particular tertiary route.

The immediate educational goal is simpler: a safe and encouraging first school term, clear understanding of scientific ideas, more independent work habits and positive participation in the school community.

Frequently asked questions for Foundation Science A

Can PSLE Score 25 choose either PG1 or PG2?

Yes. It is the official choice point between Posting Group 1 and Posting Group 2 for the ordinary S1 exercise. The selected group applies to all six school preferences.

Does Foundation Science A count as Standard Science AL6?

Foundation A contributes equivalent AL6 to the total PSLE Score, but the assessment is a Foundation paper, not the Standard Science AL6 examination.

Can a PG1 student with Foundation Science A take G2 Science?

Foundation A meets the published grade criterion for the eligible more demanding G2 subject offer from an ordinary G1 starting level, subject to the receiving school’s current procedure.

Can Foundation A alone give a PG2 pupil G3 Science?

No. The PG2-to-G3 subject criterion is Standard Science AL5 or better; Foundation A’s equivalent AL6 for posting is not a Standard AL5 grade.

Should a child who likes experiments choose PG2 automatically?

No. Enjoyment of experiments is useful, but compare scientific reasoning, English and Mathematics readiness, school support and the entire timetable. PG1 with eligible G2 Science may suit some children.

What if a PG1 school shows 30*?

It marks historical unused places after the completed posting exercise. It is not a 2027 admissions guarantee or evidence about the teaching quality.

Does the initial Posting Group permanently decide every Science option?

No. Full SBB supports later subject-level adjustments under school and MOE criteria, but eligibility must be established at each relevant stage.

Parent checklist before finalising the form

• We checked the original Foundation Science A and its equivalent AL6 contribution.
• We compared PG1 with a possible G2 Science offer against PG2 with the broader G2 starting curriculum.

• We assessed scientific reasoning, practical skills, literacy, numeracy and the child’s learning confidence.
• We researched current school programmes, safety, support, travel, CCAs and student wellbeing.
• We selected six genuinely acceptable schools in real preference order.
• We will verify the official 2027 exercise and receiving school’s subject-level offers before responding.
