TL;DR
- Predicted grades are estimates of your final examination results, provided by your teachers and submitted through the UCAS reference
- They are the single most important component of your UCAS application after your personal statement—they determine the tier of university that will make you an offer
- UK universities make conditional offers based on predicted grades, not actual grades (which aren’t available until after offers are made)
- Teachers’ predictions are accurate approximately 40–50% of the time; over-prediction is slightly more common than under-prediction
- If your predicted grades are too low for your target universities, there are strategies for negotiating—but they must be evidence-based, not emotional
- For international students in education systems without a tradition of grade prediction, the process is unfamiliar and risks of misprediction are higher
How Predicted Grades Work
Who Makes the Predictions
Your subject teachers provide predicted grades. These are collated by your UCAS referee (usually a form tutor, head of year, or school counsellor) and submitted as part of the UCAS reference.
Teachers are asked to predict “the grade the applicant is most likely to achieve” based on:
- Performance in internal examinations and mock exams
- Coursework and classwork over the duration of the course
- Professional judgment about the student’s trajectory and work ethic
- Comparison with previous cohorts at the school
What Gets Predicted
For standard UK qualifications:
- A-Levels: A grade for each subject (A*, A, B, C, D, E)
- IB: Total points plus Higher Level subject grades
- Scottish Highers/Advanced Highers: As above
For international qualifications, the format varies. Common international predictions include:
- US AP: Predicted scores (5, 4, 3, etc.) for each AP subject
- European Baccalaureate: Overall percentage and subject-level predictions
- Indian Standard XII: Percentage predictions by subject
- Other national qualifications: As specified by UCAS country guidance
If your qualification system has no tradition of predicted grades, your referee should provide their best professional estimate. This unfamiliarity increases the risk of inaccurate prediction.
When Predictions Are Made
Predictions are typically made in the autumn term (September–November) of the final year of secondary education. This means they’re based on approximately 60–70% of the course content, with a significant portion of the syllabus still to be taught and assessed.
For international students whose academic year runs on a different calendar (e.g., January–December), predictions may need to be made even earlier, based on less evidence. This is a structural disadvantage that can be partially mitigated by providing additional evidence to your referee.
How Accurate Are Predicted Grades?
Research on prediction accuracy produces sobering results. The outcomes for students are as follows:
1、 Achieve exactly predicted grades · 20–25% of students 2、 Underperform vs predictions (achieve lower) · 35–40% of students 3、 Overperform vs predictions (achieve higher) · 35–40% of students
In other words, predictions are accurate for about one in four students. The remaining three-quarters either over- or under-perform relative to their predictions.
Who Gets Under-Predicted?
Research from UK universities identifies several groups at higher risk of under-prediction:
- Students from schools with historically low progression to higher education: Teachers at such schools may have lower expectations calibrated by their school’s historical outcomes rather than individual student potential
- High-achieving students in lower-performing cohorts: The strongest student in a weak cohort may still be predicted lower than a median student in a strong cohort
- Late developers: Students whose performance has recently improved significantly—but whose teachers haven’t updated their expectations
- Students in education systems unfamiliar to the referee: International qualifications the referee hasn’t predicted before are more likely to be estimated conservatively
Who Gets Over-Predicted?
- Students at high-performing independent and selective schools: “Grade inflation” is more common where teachers expect strong results as the norm
- Students who perform well in coursework but less well in timed examinations: Coursework performance can inflate predictions that timed exams don’t fulfil
- Students who are personable and advocate strongly for themselves: Social dynamics affect predictions—teachers are human
What to Do If Your Predictions Are Too Low
Step 1: Gather Evidence
Before approaching your teacher, collect:
- Recent examination results that support a higher prediction
- Marked coursework or essays at the target grade level
- Performance data that shows an upward trajectory
- Any standardised test results (e.g., UCAT for medicine, admissions test practice scores)
- Comparative data: if you scored higher than peers who received higher predictions, document this
Step 2: Request a Meeting
Ask for a private meeting with your subject teacher. The request itself should be professional: “I’d like to discuss my predicted grade for [subject] and share some evidence about my recent performance. Would you have 10 minutes this week?”
Step 3: Present Your Case
The conversation should be evidence-based, not emotional:
Effective: “In the past three topic tests, I’ve scored 78%, 82%, and 85%—consistent with an A grade. I’ve also completed additional practice papers and can share those results. Based on this trajectory, do you think an A prediction would be justified?”
Ineffective: “I really need an A to get into Bristol and my parents will be disappointed if I don’t get it.”
Effective: “I understand the prediction is based on the evidence you have. Here’s additional evidence that might not have been available when you made the initial assessment.”
Ineffective: “Everyone else in my friendship group got predicted higher than me.”
Step 4: If the Teacher Declines
Teachers may decline to change a prediction for legitimate reasons: insufficient evidence, inconsistency in performance, or professional judgment that the higher grade is unlikely. If this happens:
-
Ask for specific feedback on what would need to change for a higher prediction. “What specifically would I need to demonstrate for you to revise the prediction upward?” This gives you actionable information.
-
Request that the referee’s UCAS reference note your trajectory: “X’s performance has improved significantly over the course of the year, with recent results at A-grade level.” A reference that contextualises a modest prediction with evidence of improvement can mitigate the impact.
-
Focus on the remaining assessments. If your teacher is willing to revisit the prediction after the next set of internal examinations, plan to deliver strong results.
-
Adjust your UCAS strategy. If your predictions are genuinely lower than your capability, you have several options:
- Apply to universities with slightly lower entry requirements, secure a place, and consider transferring or pursuing a master’s at a higher-ranked university later
- Take a gap year, achieve your actual grades, and reapply with results in hand (unconditional offers are possible with achieved grades)
- Apply to one or two aspirational choices anyway—some universities make offers below their published entry requirements for strong applicants, though this is uncommon at the most selective institutions
For International Students: Special Considerations
If Your School Doesn’t Normally Predict Grades
Many international schools—particularly those outside the British curriculum system—don’t have established grade prediction processes. If this describes your situation:
-
Educate your referee: Provide them with UCAS reference guidance (available on the UCAS website). Explain that predicted grades are expected and that universities rely on them for conditional offers.
-
Provide your own evidence: Give your referee your complete academic record, including any standardised test scores, internal examination results, and coursework grades. The more data they have, the more informed their prediction.
-
Request subject-level predictions: If your referee is a counsellor who doesn’t teach you, ask them to consult your subject teachers for grade-level input.
If Your Qualification Is Rarely Seen by UK Universities
If you’re applying with qualifications that are uncommon in the UK (e.g., a specific national baccalaureate, a technical diploma), your referee should explain the grading system in the UCAS reference. A brief note—“Grade 18/20 in the French Baccalauréat is equivalent to A*AA at A-Level”—provides essential context for admissions tutors who may not be familiar with your qualification system.
FAQ
Q: Can predicted grades be changed after the UCAS application is submitted? A: Yes, but the process is cumbersome. Your referee must contact each university individually to update the prediction. Most universities accept updated predictions, but there’s no guarantee they will reconsider an application that has already been assessed. It’s much better to get predictions right before submission.
Q: Do universities know that predictions are often inaccurate? A: Yes. Admissions tutors are well aware of prediction inaccuracy. This is one reason why universities use other selection methods: interviews, admissions tests, and personal statements all provide additional evidence. It’s also why some universities make offers to students who narrowly miss their conditions—they understand that underperformance on the day doesn’t necessarily reflect capability.
Q: What if my school refuses to predict grades at all? A: This is rare but can happen with some international schools. Contact your target universities’ admissions teams directly. Explain the situation and ask how they would like to handle it. Most will accept a reference that describes your academic performance in detail without formal predicted grades, though this may affect the competitiveness of your application.
Q: Should I ask for a higher prediction than I think I can achieve? A: No. This is a self-defeating strategy. An in
