Baseline assessments are short tests administered to Year 7 pupils in September, giving schools an independent picture of where each child starts. They are not high-stakes exams, do not appear on any official record, and are entirely separate from GCSEs. Schools use them to set pupils, identify support needs, and track progress.
Why do secondary schools use baseline assessments?
Secondary schools receive KS2 SATs data from primary schools, which gives an indication of each pupil's attainment in reading, maths, and grammar by the end of Year 6. However, KS2 data has limitations:
- It reflects performance at one point in time (May of Year 6) and can be affected by last-minute preparation
- It comes from many different primary schools with varying standards and teaching approaches
- It does not capture information about reasoning ability, learning potential, or the gap between attainment and underlying capability
Baseline assessments allow secondary schools to build their own independent starting-point picture for each pupil. This is used for:
- Setting and grouping: Results inform initial ability-set decisions for subjects such as maths, English, and science
- Identifying support needs: Pupils with low reading ages or weak numeracy who were not flagged in primary school can be identified quickly
- Identifying potential underachievers: Pupils with high cognitive ability but lower prior attainment — often due to disadvantage or lack of stretch in primary school — can be given additional challenge
- Progress tracking: Having a Year 7 baseline makes it possible to measure genuine value-added progress over five years, independently of where the pupil started
What baseline assessments do schools typically use?
There is no national prescribed baseline test for secondary schools — each school chooses what to administer. The most widely used assessments are:
| Assessment | What it measures | Provider |
|---|---|---|
| CAT4 (Cognitive Abilities Test, 4th edition) | Verbal, non-verbal, quantitative, and spatial reasoning — a profile of cognitive potential | GL Assessment |
| MidYIS (Middle Years Information System) | English, maths, and general reasoning skills; generates a "MidYIS score" and progress predictions | Centre for Evaluation and Monitoring (Durham University) |
| NGRT (New Group Reading Test) | Reading comprehension, vocabulary, and inference skills | GL Assessment |
| NFER Reading Test | Standardised reading assessment at secondary level | NFER |
| PUMA (Progress in Understanding Mathematics Assessment) | Numeracy and mathematical understanding | Hodder Education |
Many schools use a combination — for example, the CAT4 for cognitive profile plus an NGRT or NFER reading test for literacy. Some schools add a numeracy or maths screening test. The exact combination varies by school.
What is the CAT4 and why is it widely used?
The CAT4 is the most common baseline assessment in UK secondary schools. It measures cognitive reasoning ability across four batteries:
- Verbal reasoning: Understanding and using language — vocabulary, verbal analogies, sentence completion
- Non-verbal reasoning: Identifying patterns and relationships in shapes and figures
- Quantitative reasoning: Numerical patterns, sequences, and relationships
- Spatial reasoning: Visualising and manipulating shapes in two and three dimensions
The four batteries together generate a CAT4 Standard Age Score (SAS) and age-standardised percentile rankings. They also produce a profile that highlights relative strengths and weaknesses — for example, a pupil might have strong spatial and quantitative reasoning but weaker verbal reasoning, which has implications for how they best process information.
Schools use CAT4 because it measures potential rather than prior teaching — a pupil who had an impoverished primary education may score higher on CAT4 than their KS2 results suggest, helping the school identify pupils who may be underperforming relative to their ability.
What does a baseline assessment report tell parents?
Schools handle the communication of baseline results differently. Some share full reports with parents; others share only summarised findings or mention them at Year 7 parents' evening. Results typically include:
- A standardised score (100 is usually average for the age group)
- An age-equivalent score (e.g. "reading age 12 years 4 months")
- A percentile rank (e.g. "64th percentile" — performing better than 64% of the norm group)
- In the case of CAT4, a profile across the four reasoning areas
Parents should not be alarmed by a score below 100 — 100 is the average by design, so exactly half of all pupils score below it. A score in the 85–115 range is broadly average. Scores below 80 or above 120 warrant attention in different ways.
What should parents do with the results?
- Do not over-interpret a single test. Baseline assessments are one data point, not a definitive measure of intelligence or future academic potential. A pupil who had a bad day, is anxious, or finds standardised tests particularly stressful may score lower than they would on a different day.
- Ask questions if something seems surprising. If your child has always read confidently at home and their reading age comes back as significantly below their chronological age, it is worth discussing this with the form tutor or SENCO. Some pupils perform very differently in a timed, unfamiliar test than in a relaxed setting.
- Be aware of set decisions based on results. If your child is placed in a lower set for maths or English based partly on baseline data and you believe this does not reflect their capability, raise this with the relevant subject teacher with specific examples of their primary school work.
- Use it as a conversation starter. Talking with your child about how they found the tests, whether they felt they understood the questions, and how they thought they did gives valuable information about confidence and test-taking approach.
Frequently asked questions
Are Year 7 baseline assessments the same as KS2 SATs?
No. KS2 SATs are taken in Year 6 at primary school, are administered nationally by the DfE, and test curriculum content in reading, maths, and grammar. Year 7 baseline assessments are chosen and administered by individual secondary schools. They are not national tests, not reported to any government body, and do not appear on any official school record. They are purely for the school's internal use.
Can my child fail a Year 7 baseline assessment?
No. Baseline assessments are not pass/fail tests — they generate scores on a scale that describes where a pupil sits relative to a national comparison group. The lowest possible score is still a data point, not a failure. Schools use these scores to understand where a pupil is starting from and what support they might benefit from — not to label children or make permanent decisions.
Will the baseline results affect my child's future exam results?
Not directly. The results do not feed into any formal academic record or GCSE grade. However, they do influence initial set placements, which affect the pace and level of teaching a pupil receives in Years 7, 8, and 9. In subjects where setting is used, being initially placed in the wrong set can affect progress until movement to a more appropriate set occurs.
Do all secondary schools administer baseline assessments?
No. The use of baseline assessments is a school-level decision. Many schools use them widely; others use them only for specific subjects or not at all. If you want to know what assessments your child's school uses and when, ask the SENCO or head of year before September — it helps to prepare children for what to expect rather than encountering unfamiliar tests without warning.
