The National Reference Test (NRT) is a survey taken each March by a selected sample of Year 11 students in England. It does not affect individual grades. Its purpose is to help Ofqual track whether the GCSE cohort's ability is changing year on year, so grade standards can be held stable.
Why does the National Reference Test exist?
GCSE grades are intended to represent consistent standards: a grade 7 this year should mean roughly the same level of attainment as a grade 7 five years ago. The problem is that exam papers change each year and the ability profile of the student cohort changes too — some years the cohort may be more academically able than others. Without an independent measure, it is difficult to tell whether a rise in grade 7 results reflects genuine improvement in pupil achievement or a slightly easier set of papers.
The NRT provides that independent measure. By testing a representative sample of Year 11 students each March — before GCSEs are sat — and comparing the results year on year, Ofqual can track whether the ability of the typical Year 11 cohort is rising, falling, or staying the same. This information feeds into grade-boundary decisions made in August.
Who runs the National Reference Test?
The NRT is administered by the National Foundation for Educational Research (NFER) on behalf of Ofqual (the Office of Qualifications and Examinations Regulation), England's independent exams regulator. NFER is an established educational research body with decades of experience conducting large-scale assessments and surveys.
Which subjects does the NRT cover?
The NRT currently tests two subjects only:
| Subject | What is tested |
|---|---|
| English Language | Reading comprehension and writing tasks broadly aligned to GCSE English Language content |
| Mathematics | A range of skills broadly aligned to GCSE Mathematics content |
Results from the NRT inform Ofqual's approach to grade boundaries in GCSE English Language and GCSE Mathematics — two of the most widely taken and societally significant qualifications in England.
How are schools and students selected?
The selection process is carefully designed to produce a nationally representative sample:
- A sample of approximately 300 secondary schools across England is selected each year, stratified by region, school type, and pupil characteristics
- Within each selected school, a random sample of Year 11 students is chosen
- In total, approximately 30,000 Year 11 students take part in any given year
Neither schools nor individual students can volunteer to take part — selection is made by NFER. Schools that are selected are required to participate, though individuals within a school may be excused in exceptional circumstances (such as illness on the day).
Does the NRT affect individual students' grades?
No. The NRT results are entirely separate from GCSE grades. Students' NRT results are:
- Not shared with the student or their parents
- Not shared with the school in any format that identifies individuals
- Not recorded on any school or public database linked to the student's name
- Not included in school performance tables or Ofsted assessments
The NRT is explicitly designed to be low-stakes for everyone involved. Students should approach it calmly — a poor performance on the NRT does not hurt their GCSE or harm their school's performance data in any way.
What do the tests actually involve?
The NRT tests are paper-based, sat in normal exam conditions, and take roughly one to two hours per subject. They are broadly similar in style to GCSE papers — students write answers in a booklet in response to reading or mathematical tasks — but the papers are specifically designed for the NRT and are not the same as the actual GCSE papers sat in May and June.
Students take either the English Language NRT, the Mathematics NRT, or in some cases both. Schools are given notice well in advance so that the date can be accommodated in the school timetable without disrupting GCSE revision.
How does the NRT feed into GCSE grading in August?
When Ofqual and the exam boards set grade boundaries in August, they draw on several sources of evidence, including:
- Statistical predictions based on prior attainment of the cohort
- Examiner judgements about where work on the grade boundaries sits
- Comparable outcomes methodology (comparing performance with similar cohorts in previous years)
- NRT data — if the NRT shows the Year 11 cohort is genuinely stronger or weaker than last year's, this is taken into account when deciding whether a slightly easier or harder boundary is justified
The NRT adds an independent, pupil-level data point that is not influenced by teaching quality, marking practice, or school performance pressures — which makes it a more neutral indicator of true cohort ability than exam results alone.
Frequently asked questions
Will my child be told if they are selected for the NRT?
Yes. Schools inform selected students before the test date. The school will typically tell them it is a national survey test, that results will not affect their GCSE grades, and that they should simply try their best. The letter home is usually brief and reassuring.
Is participation compulsory for students who are selected?
Selected schools are required to participate and must make reasonable efforts to ensure selected pupils attend. Individual pupils cannot opt out on the grounds of preferring to use the time for GCSE revision. However, pupils who are genuinely ill on the day are not compelled to take the test.
Does the NRT exist in Wales, Scotland, and Northern Ireland?
The NRT is an England-specific measure overseen by Ofqual. Wales, Scotland, and Northern Ireland have their own qualifications regulators (Qualifications Wales, SQA/Qualifications Scotland, and CCEA respectively) and their own approaches to maintaining grade standards. No equivalent test runs in those nations under the same name or framework.
Has the NRT changed how GCSE grades are set since it was introduced?
The NRT was first administered in March 2017. Ofqual has reported using its results to inform discussions about cohort ability in subsequent years. Its influence is one input among several — it does not single-handedly determine grade boundaries — but it gives Ofqual a more robust basis for defending grading decisions, particularly in years when there is public debate about whether grade changes reflect real improvements or easier marking.
