What are predicted grades, and how do UK universities use them?

Question

A predicted grade is the grade a student's teacher or school expects them to achieve in a qualification (A-Levels, the IB, and similar) before the final exams are sat. UK universities apply through UCAS, where these predictions — not final results — are what most conditional offers are based on: the university offers a place on the condition that the student actually achieves specified grades on results day. Who assigns them, and why they matter more than families expect: predicted grades come from the school, based on teacher assessment of ongoing work — the student does not choose their own. Because UK applications are submitted in the autumn, roughly a year before final exams, the university has no real results to judge; the prediction is the number the offer hangs on. A school that predicts too conservatively can cost a child an offer they'd have earned; this is why choosing a school with a credible, well-calibrated prediction track record matters for a UK-bound student. Predictions are frequently wrong, and universities know it. Research summarised across UK sources puts predicted-grade accuracy at only around half — with the errors skewed heavily toward over-prediction (schools predict higher than the student ultimately achieves) rather than under-prediction. Accuracy varies by school, subject, and student. The practical takeaway: an ambitious predicted grade gets you the offer, but results day is what actually counts — build the plan around the real exam, not the prediction. What happens on results day, in plain terms. If the student meets (or beats) the grades in their firm-choice conditional offer, the place is confirmed. If they narrowly miss, many universities still confirm — a near-miss is not an automatic rejection. If the firm choice is lost, the insurance choice (a second, usually lower offer) acts as the backup. If both are missed, Clearing — which opens in July — matches unplaced students to courses that still have vacancies, and every year strong students find good places through it. (Note: 'Adjustment', the old route for students who exceeded their offer, was discontinued in 2022.) For relocating families coming from a GPA/transcript system, this is the biggest mental adjustment: US-style admissions weigh a multi-year record already in hand, whereas the UK effectively admits on a forecast and then verifies it against one set of terminal exams. That makes the final exam sitting far higher-stakes than families used to continuous assessment expect — and makes the school's predicting behaviour a real, if invisible, part of the application.
