A practical sequence for reviewing your department's GCSE results without jumping too quickly to conclusions.
GCSE results analysis is most useful when it moves beyond a single headline such as the percentage achieving grade 4+ or grade 7+. A strong review looks at the whole grade distribution, compares it with appropriate national data, considers the characteristics of the cohort and identifies questions worth investigating further.
Start with the facts. How many students were entered? What proportion achieved each grade? How does the distribution compare with last year and with the national picture? Then add context before deciding what the results mean.
A results analysis should help you understand performance. It should not be an exercise in finding a simple explanation for every difference.
Record the number of students entered and the number achieving each grade from 9 to U.
Cohort size matters. If 20 students took a subject, one student represents 5% of the cohort. A movement of a few percentage points may therefore represent just one student.
Look at actual student numbers alongside percentages.
Useful benchmarks may include:
Do not rely on grade 4+ alone. Two departments can have the same grade 4+ rate but very different distributions above and below that threshold.
A department might, for example, maintain its grade 4+ rate while increasing the proportion achieving grades 7–9. That is an important change that a single headline measure would miss.
Use the tutor2u Exam Results Explorer to select the qualification, subject, exam board and year.
The My results tool allows you to enter your own grade distribution and compare it with national results.
Treat this as a benchmark rather than a judgement.
National results describe all candidates represented in the published data. Your own students may differ in prior attainment, demographics, entry policy and curriculum experience.
For GCSE English Language and Mathematics in particular, national all-age figures can include post-16 resit candidates, so they are not always a direct Year 11 comparison.
Ask:
Has the cohort size changed?
Has the prior-attainment profile changed?
Has the specification or assessment changed?
Are you comparing like with like?
Are the national figures provisional or final?
A change from 63% to 67% at grade 4+ is a rise of four percentage points, not 4%.
Your first analysis might identify that:
Those are useful findings.
The next stage is to investigate why.
Avoid conclusions such as “Paper 2 teaching was weak” or “the cohort underperformed” until you have looked at scripts, question-level evidence, prior attainment and other relevant information.
A good results review should lead to a manageable set of questions or actions.
For example:
“Review extended-response performance using scripts and question-level data.”
“Investigate the group of students finishing one grade below their target.”
“Check whether our curriculum sequencing gives enough time to Topic X.”
That is much more useful than producing a long list of percentages.
Enter your department or class results into the tutor2u Exam Results Explorer and compare your grade distribution with the national picture.
