What Are Predicted Grades?

Predicted grades are a teacher's best estimate of the grade a student will achieve in their final examinations. In the UK education system, they serve several important purposes:

  • UCAS university applications — submitted with A-Level predictions for conditional university offers
  • Sixth-form and college applications — GCSE predictions inform entry requirements for post-16 courses
  • Scholarship applications — many scholarship bodies use predicted grades as eligibility criteria
  • Clearing preparation — accurate predictions help students plan for results day scenarios

How Teachers Set Predicted Grades

Subject teachers are responsible for setting predicted grades. They draw on a range of evidence to make their assessment:

Mock Exam Performance

Mock examinations are the most significant factor. Schools typically run at least one full mock exam series, often in December or January of Year 13 (or Year 11 for GCSE). A student's mock grade is usually the starting point for predictions, though teachers adjust up or down based on other factors.

Classwork and In-Class Assessments

Regular class tests, essay marks, problem sets, and in-class assessments give teachers ongoing evidence of a student's ability. A student who consistently achieves 80% on class tests but achieved 65% on a mock due to poor exam technique may receive a prediction higher than the mock grade.

Coursework

Where a subject includes coursework (such as NEA in A-Level subjects), teachers have direct evidence of achievement. Coursework marks — which represent a proportion of the final grade — feed directly into the prediction.

Engagement and Progression

Teachers consider the student's trajectory. A student who started the course achieving grade C/D work but has progressively improved to A/A* work would likely receive a higher prediction than their earliest assessment suggests. Similarly, a student who was achieving A* work but appears to have plateaued or declined will not automatically receive an A* prediction.

Historical Data

Experienced teachers draw on years of data about their students and how mock performance correlates with final exam outcomes. Schools also have access to DfE contextual data about how students with similar prior attainment (Key Stage 4 or GCSE) perform at A-Level nationally.

Predicted Grades and UCAS University Applications

When applying to university through UCAS, predicted A-Level grades are submitted alongside the application. Universities use these grades to decide whether to make a conditional offer — an offer that becomes firm once the student achieves the specified grades in their actual examinations.

UCAS Timeline

  • Mid-October (Year 13): UCAS deadline for Oxford, Cambridge, medicine, dentistry, and veterinary science applications
  • Late January (Year 13): Main UCAS deadline for other university applications (5 choices)
  • March onwards: Universities respond with conditional or unconditional offers
  • May: Students firm and insure their choices
  • August (Results Day): Conditional offers confirmed or cleared

Conditional Offers

Most university offers are conditional, requiring specific A-Level grades (e.g., "AAB including Biology"). If you meet or exceed these grades on results day, your place is automatically confirmed. If you fall short of your firm choice but meet your insurance choice (typically a lower-grade offer), you go to that university instead.

Contextual Offers

Many universities, particularly Russell Group institutions, now make contextual offers to students from disadvantaged backgrounds, state schools, or certain postcodes. These offers are typically one or two grades lower than standard (e.g., ABB instead of AAA). Eligibility is determined by the university's own criteria, often using DfE data about school performance and free school meal eligibility.

Research evidence: A 2016 study by UCAS and the Institute for Fiscal Studies found that predictions are optimistic more often than pessimistic, with students from state schools tending to be under-predicted relative to independent school students. This disparity has led to calls for contextual admissions reform.

How to Improve Your Predicted Grade

If you want to improve your predicted grade — or challenge one you believe is too low — here is what you can do:

Build Your Evidence Base

Teachers must be able to justify predictions with evidence. The most persuasive evidence is a strong performance in formal assessments, particularly mock examinations. If your mock results are lower than your class performance suggests, speak to your teacher about this.

Request a Meeting

Politely request a one-to-one meeting with your subject teacher. Come prepared with your recent assessment grades, noting any upward trend. Ask specifically what grade they are predicting and what evidence they are using. If you disagree, explain your reasoning calmly and professionally.

Involve Your Tutor or Head of Year

If you cannot resolve a disagreement with the subject teacher, speak to your form tutor, sixth form tutor, or head of year. They can review your overall academic profile and may be able to facilitate a conversation with the teacher.

Gap Year and Deferred Entry

If your predicted grades do not meet the requirements for your chosen courses, consider whether a gap year gives you the opportunity to resit exams and apply with actual grades rather than predictions. Some universities prefer or specifically invite applications with actual results, and this removes the prediction uncertainty entirely.

Why Predictions Are Sometimes Low

Teachers may under-predict because they are cautious by nature, because they want to avoid disappointed students, or because their school has a policy of conservative predictions to avoid complaints when students underperform. Some schools inflate predictions to support university applications, though exam boards and universities are increasingly aware of this practice and contextualise predictions accordingly.

Clearing and Adjustment on Results Day

Results day in August is when your actual A-Level grades are released and UCAS offers are confirmed or cancelled. Several scenarios are possible:

You Meet Your Firm Offer

If you achieve the grades required by your firm choice, your place is automatically confirmed. No further action needed.

You Miss Your Firm Offer but Meet Your Insurance

Your insurance university confirms your place. You can choose to accept this or enter Clearing to find alternative options, but be aware that your insurance place is not held indefinitely once you enter Clearing.

You Miss Both Offers (Clearing)

UCAS Clearing opens on results day and allows you to contact universities with available places. You call the university directly using a Clearing number visible on UCAS Track. Many excellent universities and courses have places available through Clearing, and you may find a better fit than your original choices.

You Exceed Your Offer (Adjustment)

If you significantly exceeded your predictions and your firm offer, UCAS Adjustment allows you to contact higher-ranked universities to see whether they have places. Crucially, you keep your confirmed place while exploring Adjustment options — you cannot be left without a place.

Frequently Asked Questions

What are predicted grades and who sets them?
Predicted grades are estimates of the grade a student will likely achieve in final examinations. They are set by subject teachers based on evidence including mock exam results, class assessments, coursework, and engagement over the course. They are submitted to UCAS as part of university applications and to post-16 institutions for GCSE applications.
Are predicted grades accurate?
Research indicates approximately 50% of students achieve their predicted grades. Around 35–40% achieve below predictions, and around 10–15% exceed them. Predictions tend to be slightly optimistic overall. Accuracy varies by school type — independent schools tend to have more accurate predictions than state schools, partly because they may have more experience with the UCAS process.
Can I challenge my predicted grade?
Yes. You can request a meeting with your subject teacher and present evidence of your performance. Show mock results, practice paper marks, and any improvement trend. If the teacher is unwilling to reconsider, speak to your head of year or sixth form coordinator. Schools should be able to justify their predictions with evidence, and if yours appears inconsistent with your performance record, you have reasonable grounds to challenge it.
When are predicted grades submitted to UCAS?
A-Level predictions are submitted as part of the UCAS application, which opens in September of Year 13. The deadline for medicine, dentistry, veterinary science, Oxford, and Cambridge is mid-October. The main deadline for all other universities is late January. Predictions must be in place before these deadlines.
What happens if I exceed my predicted grade?
If you exceed your predicted grades and already meet your conditional offer, your place is confirmed. If you significantly exceeded your predictions, you can register for UCAS Adjustment on results day to explore whether a higher-ranked university will accept you. You keep your existing confirmed place while exploring Adjustment — you cannot lose out by trying.
Do predicted grades affect my GCSE application?
Yes. GCSE predicted grades (usually based on mock exams and teacher assessment) are used by sixth forms and colleges to decide what conditional offers to make for A-Level, BTEC, or other post-16 courses. A sixth form requiring grade 6 in Maths for A-Level Maths will make a conditional offer based on whether your GCSE prediction meets that threshold.
What is UCAS Clearing?
UCAS Clearing is a process run in August after A-Level results day that matches students who did not receive a confirmed place (because they missed their offers) with universities that have available places on their courses. You call universities directly using a Clearing number. Many students find excellent courses through Clearing that suit them better than original choices.
