Exam results

How to read GCSE, A level, IB, and destination data without being dazzled by selective-school marketing.

  • Raw results are partly a measure of intake selectivity.
  • Destinations and value-add tell a different story from headline grades.
  • Compare like with like: GCSE, A level, IB, and BTEC results are not interchangeable.

Who it is for

This guide is for parents comparing independent senior schools, sixth forms and boarding schools through GCSE, iGCSE, A level, IB Diploma, BTEC, EPQ and leavers' destination data. It is especially useful at 11+, 13+ and 16+, when results pages can feel like a clean way to rank schools but are actually full of traps: selective intake, small cohorts, qualification mix, value-added claims, university offer language and missing denominators.

It is also for parents who are not trying to choose the "most academic" school in the abstract. A results page should help you answer a more personal question: what happens to pupils like my child at this school? A child who is already in the top academic band may need stretch, subject depth and ambitious destination support. A child who is bright but uneven may need teaching that adds value rather than a school that mostly admits pupils who were already very high-attaining. A child with anxiety, dyslexia, EAL or a passion outside the exam mainstream needs a different reading of the same data.

The guide focuses on England and UK independent schools, with London examples where they help. It uses official sources such as Ofqual, JCQ, UCAS, the International Baccalaureate, DfE and ISC, then pairs them with school examples.

Summary

Exam results matter, but raw results are partly a measure of who was admitted in the first place. A school with 90% A*/A at A level may be teaching brilliantly, but it may also have selected pupils with extremely high prior attainment, required strong GCSE grades to enter sixth form, limited weak subject choices, and supported a culture where pupils below the top band leave before the published result point. None of those facts automatically makes the school bad. They simply change what the headline means.

For GCSE and iGCSE, parents often look at the percentage of grades 9-7, or 9-8 for more selective schools. For A level, the usual shorthand is A/A and A-B. For IB Diploma, parents should look at average points, pass rate, proportion at 40+ and subject-grade distribution. For destinations, parents should distinguish offers, firm choices and confirmed places. "Russell Group offers" is not the same as "Russell Group destinations". "Oxbridge success" is more meaningful if the school also tells you how many applied.

Qualification mix matters. Many independent schools use iGCSEs, and the ISC notes that iGCSE use can make DfE performance-table comparisons misleading because some iGCSEs are not counted in the same way. Sixth forms may report A level results with or without EPQ, BTEC or other Level 3 qualifications. IB schools may compare Higher Level grades with A level grades, but those equivalence tables are interpretive rather than universal.

The pandemic years still distort trend lines. Ofqual explains that 2020 and 2021 relied on alternative grading arrangements, 2022 was transitional, and England returned toward pre-pandemic grading standards by 2023. Parents should not treat a 2020-2022 spike as a normal school-improvement trend. Ask for 2019, 2023, 2024 and 2025 side by side, then read 2026 when it is published.

Value-added can help, but it is not a magic fix. It tries to measure progress from starting point, which is exactly what parents need. Yet public progress measures are patchy for independent schools, and DfE guidance says Progress 8 cannot be calculated for 2024/25 and 2025/26 because relevant Key Stage 2 prior-attainment data was unavailable after Covid disruption. Schools may use internal or external baselines such as MidYIS, Yellis, ALIS, CAT scores, GCSE average or their own data. Ask what baseline is used, who verifies it and how many pupils are included.

The best reading is layered. Start with raw attainment. Add cohort size. Add selectivity. Add value-added. Add subject breadth. Add destinations. Add pastoral and SEN support. Then ask whether the school can talk about pupils outside the highest-achieving group with the same confidence it uses for the league-table group.

Key dates

For the 2026 exam season, Ofqual says GCSE, AS and A level exams run from 7 May to 23 June 2026, with a JCQ contingency day on 24 June 2026. Parents should not book immovable travel before the contingency day. The JCQ key dates and Ofqual rolling update are the official places to check.

IB Diploma and Career-related Programme results for May exam sessions are released to candidates from 12:00 GMT on 6 July. The IB confirms this on its assessment FAQ. This earlier date matters for families comparing IB and A level sixth forms, because IB pupils may know outcomes before A level candidates.

A level, AS and many Level 3 results are released on Thursday 13 August 2026. JCQ's release of results notice sets candidate access from 08:00. UCAS also runs confirmation and clearing around that morning, with the UCAS key dates giving timings for applicants and advisers.

GCSE results day is Thursday 20 August 2026, also from 08:00 under JCQ arrangements. For Year 11 pupils moving into sixth form, that day is not just a celebration; it may determine subject choices, school transfer, bursary conditions and whether a pupil meets the sixth-form offer.

For university entry, UCAS dates shape how schools describe destinations. For the 2026 cycle, 15 October 2025 was the equal-consideration deadline for Oxford, Cambridge, medicine, dentistry and veterinary courses; 14 January 2026 was the main equal-consideration deadline; Clearing opens on 2 July 2026; and the final application deadline is 24 September 2026. For the 2027 cycle, applications can be submitted from 1 September 2026, with 15 October 2026 and 13 January 2027 the main equal-consideration dates. Check the live UCAS dates page.

Independent-school admissions dates are separate. London 11+ Consortium schools, City of London School, Westminster, NLCS, Dulwich and other selective schools set their own registration and assessment calendars. Results data can help shortlist, but admissions deadlines decide whether you can still apply.

Parent checklist

  • Ask for cohort size. A subject with four pupils can produce dramatic percentages that do not prove department strength.
  • Ask whether figures are by entries, candidates or pupils. One pupil taking ten GCSEs creates ten entries.
  • Separate GCSE and iGCSE. Ask which subjects use which qualification and whether they are counted in external tables.
  • For GCSE, compare 9, 9-8, 9-7 and English/maths outcomes rather than one cherry-picked line.
  • For A level, ask for A, A/A, A*-B and pass rate. Then ask whether EPQ or BTEC is included.
  • For IB, ask for average points, pass rate, average subject grade, 40+ share and cohort size.
  • For destinations, ask for confirmed places, not only offers.
  • Ask how many applied to Oxbridge, medicine, dentistry, veterinary science, conservatoires, US universities or art foundation if those routes are advertised.
  • Ask about pupils who joined at sixth form versus those educated through the school.
  • Ask about retention: how many pupils leave before GCSE, after GCSE or before the end of sixth form?
  • Ask for value-added data and the baseline used.
  • Treat 2020-2022 as exceptional years in trend charts.
  • Read results alongside subject choice. A narrower curriculum can raise headline outcomes while giving some pupils fewer routes.
  • Ask how the school supports pupils who miss predicted grades on results day.

How to read the data

Start with the denominator. If a school says "100% A*/A in further maths", you need to know whether that means three pupils or thirty. If a school says "50 Oxbridge offers", you need to know the cohort size and the number of applicants. If it says "90% to Russell Group", you need to know whether that is offers, firm choices or confirmed destinations.

Next, locate the selection point. Some schools select heavily at 11+. Some at 13+. Some run a very selective sixth form and require high GCSE grades for internal pupils to continue. A school with excellent A level outcomes and high sixth-form entry requirements may still be right for a highly academic child, but the result is not evidence that the school transforms average prior attainment into top grades.

Look for subject spread. A school can have a strong overall A*/A figure while a particular department is weaker, or while only small numbers take a subject your child loves. If your child wants art, computer science, classics, economics, design technology, music or a language, ask for subject-level entries and outcomes. Percentages are useful only with entry counts.

Read value-added carefully. A strong value-added school can be more impressive than a raw-results leader for some children, because it suggests pupils do better than expected from their starting points. But ask whether the score is externally benchmarked, how many pupils are included and whether it covers all subjects. A school may use ALIS for sixth form, MidYIS or Yellis lower down, CAT scores or internal baselines.

Treat destinations as evidence of guidance culture, not just prestige. A good destinations list should show range: universities, courses, apprenticeships, art foundation, conservatoires, overseas options, gap years and specialist routes. The question is whether pupils find suitable next steps, not whether every name is famous.

Finally, read the tone. Some schools write about the whole cohort; others write only about the spectacular top slice. A school that can explain support for pupils who get Bs, 5s or 6s may be more useful than a school that has no language for them.

Use results as a conversation opener, not a verdict. On an open day, choose one published claim and ask the admissions or academic lead to unpack it. If the website says "record A level results", ask whether the record came from higher A* rates, a changed subject mix, a smaller cohort, stronger sixth-form entry requirements or genuine improvement across departments. If the site celebrates medicine or Oxbridge, ask what happened to pupils applying for engineering, design, music, drama, liberal arts, apprenticeships or foundation courses. If the school publishes a long leavers' list, ask how much of that guidance starts in Year 12 and how much is reactive in the autumn of Year 13. A strong school will not be defensive about these questions; it will welcome the chance to explain how pupils are advised.

Parents should also separate attainment from workload culture. Some children are energised by a school where everyone is aiming high and peer ambition is normal. Others achieve better when academic pressure is carefully buffered by tutoring, wellbeing, sleep, sport, arts and sensible subject choices. Exam pages rarely show this. Ask pupils whether teachers mark promptly, whether mocks are used constructively, whether struggling pupils can ask for help without stigma, and whether the school is realistic about course load. The best results for your child are not always the highest published percentages; they are the outcomes achieved without breaking the child on the way.

For sixth form, pay particular attention to subject access. A school may advertise a wide A level menu, but timetabling can still make certain combinations impossible. IB schools solve some breadth problems but introduce others: pupils must keep six subjects going, and weaker maths, language or science confidence can matter. Ask how often pupils change subject after the first half term, what support exists before the first set of predicted grades, and whether university advice is built around the pupil's actual strengths rather than the school's preferred destination story.

If a school cannot answer these practical questions, keep the headline grades in proportion and look harder at the day-to-day academic system, because admissions brochures rarely reveal that operational layer.

School examples

North London Collegiate School publishes GCSE, A level and IB information together on its results and destinations page. It is a useful example of very high attainment in a highly selective context. Parents should admire the outcomes but still ask about cohort size, selection and support below the top band.

Dulwich College publishes three-year tables and candidate numbers on its examination results page. Candidate numbers are helpful because they stop percentages floating free of scale. Dulwich also provides a reminder that EPQ and subset reporting can change the story.

Sevenoaks School is an IB-focused example. Its exam results page and university destinations page show why IB schools need different reading. Average points, 40+ rate and international destinations matter more than A level shorthand.

Alleyn's School publishes results and narrative context on its exam results page. It is useful for parents comparing co-ed London day schools because the page combines achievement with subject breadth and whole-school framing.

Brampton College is a sixth-form college example. Its A level results page foregrounds both attainment and value-added claims, which lets parents ask what baseline is used and whether the result reflects progress from GCSE.

King Alfred School publishes subject-level results and has also referenced value-added. Its results and destinations page is useful because some subject cohorts are small, showing why entry counts matter.

King Edward's School Birmingham publishes IB and GCSE outcomes on its results page. It is useful because it attempts IB Higher Level to A level comparison. Parents should read those comparisons as explanatory tools, not exact conversion tables.

Stonyhurst College publishes mixed pathway data on its academic results page, including A level, GCSE, CTEC and IB. It shows why parents should ask whether a school is reporting one pathway or the whole sixth form.

Common mistakes

The first mistake is using one headline percentage as a ranking. A school can be excellent and still not be the best fit for your child. Another school can have lower raw results but stronger progress for pupils with a similar starting point.

The second mistake is comparing IB average points with A level A*/A percentages as if they are the same metric. IB pupils study six subjects plus core components; A level pupils usually specialise in three or four. Both can be rigorous, but the numbers do not line up neatly.

The third mistake is ignoring iGCSE. Independent schools often use iGCSEs for good educational reasons, but government tables and press tables may treat them differently.

The fourth mistake is reading "offers" as "destinations". Offers can be declined, missed, insured or replaced through Clearing. Final destinations are more useful.

The fifth mistake is forgetting Covid. 2020 and 2021 were not normal exam years. Trend charts need context.

The sixth mistake is missing retention. If a school loses pupils before GCSE or does not allow many internal pupils into sixth form, final outcomes describe the remaining cohort.

The seventh mistake is assuming top grades prove pastoral fit. Very high pressure can suit some children and harm others. Read results alongside wellbeing, academic support and culture.

Questions to ask

  • How many pupils were in the cohort?
  • Are figures by entry, candidate or pupil?
  • Do GCSE figures include iGCSE?
  • Which subjects have the largest and smallest cohorts?
  • Are A level results reported with EPQ or other Level 3 qualifications?
  • What are the sixth-form entry requirements for internal and external pupils?
  • How many pupils leave after Year 11, and why?
  • What value-added measure do you use?
  • Is the value-added externally benchmarked?
  • How many pupils applied to Oxbridge, medicine, US universities or art foundation?
  • Are destinations confirmed places or offers?
  • What happens on results day if a pupil misses a grade?
  • How do you support pupils outside the top academic band?
  • Can we see three-year data excluding or clearly labelling Covid years?

Useful comparison examples include Sevenoaks School, Dulwich College, Alleyn's School, North London Collegiate School, Westminster School, St Paul's School, Godolphin and Latymer, South Hampstead High School, Highgate, Brampton College, King Alfred School and King Edward's School Birmingham.

Use related schools by evidence type. IB families should compare IB schools with IB schools. A level families should compare sixth-form entry policies. Parents considering a less selective school should ask about value-added before being dazzled by raw attainment at highly selective schools.

Use school search to shortlist by age, entry point and geography, then use Compare to hold academic, pastoral, fee and commute information in one place. Use the Houseroom Index and academic leaders pages as starting points, not final answers. Pair those with the 11+ guide if results are part of an admissions decision rather than a sixth-form-only choice.

Parents would also benefit from a results decoder, a value-added explainer, an IB-versus-A-level comparator, a destinations tracker and a results-day planner. These should not replace judgement; they should force the right questions into view.
