What Are Predicted Grades? How They Work & Why They Matter
Seeing a predicted grade that feels off can be unsettling. Maybe it looks too low for the offer a student is chasing. Maybe it feels high enough to create pressure that seems unfair. Either way, the number carries real weight in a UCAS application.
This guide explains where predicted grades actually come from, how much control they hold over an application, and what a student can do if the grade on the form does not match expectations.
What Are Predicted Grades?
Predicted grades are a teacher's professional estimate of the grades a student is most likely to achieve in final exams, whether A-Levels, IB, or BTEC. They are based on classwork, mock exam results, and overall academic trajectory, and they are used mainly for UCAS applications.
These numbers do more than sit on a form. They shape which universities and courses a student can realistically apply to, and they occasionally matter for scholarships or visa applications too.
A few points are worth knowing before diving into the details. Predicted grades are not the same as target grades, which are calculated from GCSE data rather than judged holistically by a teacher.
- Subject teachers assign the initial prediction
- Heads of department or exams officers moderate it
- They appear in the reference section of the UCAS form
- Scholarships and some visa routes may also request them
Every student applying through A-Level or IB routes will see this number appear somewhere on their UCAS paperwork.
How Do UK Universities Use Predicted Grades?
Universities use predicted grades to decide whether to make an offer at all, and to set the conditions of that offer, such as AAB. This happens months before real results exist in August.
An offer can be conditional, meaning it depends on hitting certain grades, or unconditional, meaning the place is secured regardless of the final result. Most offers in the UK are conditional.
Competitive courses lean on predictions especially hard. Medicine, dentistry, and Oxbridge applications often set a high bar, and a lower prediction can rule a student out before the personal statement is even read.
Some universities now weigh predictions alongside contextual admissions data. This includes a student's school performance history, postcode, and background, which can soften the impact of a single predicted grade.
How Do Teachers Calculate Predicted Grades?
Teachers combine mock exam results, classwork performance, and improvement trends with professional judgment against known grade boundaries. The department then moderates each prediction so it is not just one teacher's opinion.
A-Level and IB processes share the same spirit but differ in the details, especially around scoring format and how mocks are weighted.
The table below compares how the two systems typically approach a prediction, so it is easier to see where the process overlaps and where it diverges.
| Factor | A-Level Process | IB Process |
|---|---|---|
| Main evidence used | Mock exams and classwork | Internal assessments and mock scores out of 45 |
| Historical benchmarking | Compared against past grade boundaries | Compared against subject-specific IB criteria |
| Sign-off | Head of department review | Coordinator and subject teacher review |
| Common risk factor | Small mock sample sizes | Inconsistent internal assessment scoring |
| Teacher tendency | Cautious optimism | Rounding up borderline scores |
Both systems rely on judgment calls, which is exactly why predictions can shift once real mock results or coursework drafts come in.
Subject choice affects accuracy too. Students working through A-Level subjects or IB subjects with structured, ongoing support tend to build the kind of consistent mock record that makes a prediction easier to trust.
Why Do Predicted Grades Matter For UCAS?
Predicted grades matter because they are often the only academic evidence universities have when reviewing an application, months before real exams take place. They directly shape which offers a student receives.
Predictions are usually submitted in the first term of year 13, roughly eight months before final results land in August. That gap is where all the pressure sits.
A predicted grade is not the sole factor in an application. Personal statements and references still carry weight, but a weak prediction can limit which doors even open for consideration.
Are Predicted Grades Usually Accurate?
Research consistently shows predicted grades are frequently over-predictions rather than exact matches. Only a minority of UK students end up achieving exactly what was predicted, which is why universities build flexibility into offers and clearing.
According to a UCU analysis of nearly 1.4 million UCAS applicants, only around 16 percent of students who achieved three A-Levels had all three grades predicted correctly, with the large majority of mismatches leaning too optimistic.
According to UCL Institute of Education researchers, predicting A-Level grades accurately is described as a near-impossible task, even when statistical models are added to teacher judgment.
Over-prediction tends to happen because teachers give students the benefit of the doubt, hoping to encourage rather than discourage effort in the final stretch before exams.
In practical terms, this means applicants should not treat a single predicted grade as fixed. Backup choices and insurance offers exist precisely because predictions and final results often part ways.
What Can Students Do If Grades Feel Too Low?
Students who feel their prediction is unfairly low do have options. The steps below outline a realistic path from raising the concern to building evidence that can shift a teacher's judgment.
- Ask the teacher directly why the grade was set where it is
- Request a formal review through the school's appeals process
- Sit an additional assessment to demonstrate recent improvement
- Submit strong coursework drafts or an improved mock as evidence
- Lean on the personal statement and reference once submission has passed
- Consider a gap year reapplication if the window has fully closed
Consistent mock practice and structured revision through resources like past papers or targeted online tutoring often produces the clearest evidence a teacher can act on before submission deadlines close.
Predicted Grades Open Doors, Final Results Decide Outcomes
A predicted grade is an estimate, not a guarantee and not a ceiling. It opens the door to an offer, but the final exam result is what actually decides where a student ends up.
Students have more agency here than it might feel like in the moment. A prediction can be questioned, supported with evidence, or improved before it locks in for good.
If a predicted grade feels out of step with what a student is capable of, book a consultation to build a plan around stronger mocks and a more accurate final prediction.
Frequently asked questions
Yes, in some cases. Schools can request an amendment through UCAS if a student's performance changes significantly, though this is handled case by case and is not guaranteed.
Sometimes. Certain scholarships and bursaries ask for predicted grades as part of eligibility screening, though core student finance in the UK is not directly tied to the prediction itself.
If a conditional offer is missed, a student may still be accepted depending on how close the result is, or they can enter Clearing to find an alternative place.
No. Target grades are usually calculated from prior data such as GCSE results, while predicted grades reflect a teacher's holistic judgment closer to the actual exam.
No. Highly competitive courses and institutions often lean on predictions more heavily, while others factor in contextual data or place more weight on the personal statement.
