What Does a Good A-Level Predicted Grade Look Like — and Can Your Child Challenge It?

Predicted grades matter more than most families realise. They determine which universities your child can realistically apply to, which offers they'll receive, and — in some cases — whether they aim high enough in the first place. Yet the process by which a teacher settles on "AAB" rather than "A*AA" is often opaque, and most Year 12 students accept whatever appears on their UCAS form without question.

Here's how predictions actually work, when it's reasonable to push back, and what your child can do between now and the autumn to give themselves a stronger case.

How teachers arrive at a predicted grade

There's no national formula. Each school sets its own policy, but predictions are typically based on some combination of:

• AS-style internal exams at the end of Year 12 (mock exams, end-of-year assessments)
• Coursework and class performance through the year
• GCSE results, especially in the same or related subject
• The teacher's professional judgement about trajectory — is the student improving, plateauing, or slipping?

Most schools also apply a house rule: predictions should be "aspirational but achievable". In practice, this often means the grade the student would get if they performed at the top of their current range on exam day. Some schools are generous; others are cautious to protect their reputation with universities.

That variation matters. A student predicted AAB at one school might well be predicted A*AA at another with identical performance. Universities know this, which is partly why they use contextual data — but the prediction on the form is still the number that triggers (or blocks) an offer.

What a "good" prediction looks like

There's no universal answer, but a useful benchmark is this: a good predicted grade is one that reflects your child's realistic best performance if they continue to work well, not their average performance across a mixed Year 12.

Some rough guides:

• A* predictions usually require consistent top-band work in Year 12 mocks (often 85%+ in linear subjects), strong essay/problem quality, and — in essay subjects — a genuine flair beyond just knowing the content.
• A predictions typically follow from consistent high performance in the 70–85% range, with the teacher confident the student can push higher under exam pressure.
• B predictions suggest the student is competent but has visible gaps — either in content, exam technique, or consistency.

If your child is being predicted a grade lower than they got at GCSE in the same subject, that's worth a conversation. It's not always wrong — A-Levels are a significant step up, and a Grade 9 at GCSE doesn't automatically translate to an A* — but it deserves an explanation.

Legitimate grounds for challenging a prediction

Schools are used to parents asking about predictions. What they respond well to is evidence, not opinion. Genuine grounds include:

• A clear upward trajectory. If early Year 12 mocks were weak but recent work has been consistently stronger, the prediction should reflect where the student is now, not where they started.
• Mitigating circumstances during the assessment used. Illness, bereavement, or disruption around the mock exams that the school may not have fully weighed.
• Strong evidence outside internal exams. Independent work — essay competitions, EPQ progress, olympiad results, external assessments — that shows capability beyond what mocks measured.
• Inconsistency between subjects. If your child is predicted A* in two subjects and B in a third despite similar effort and comparable GCSE grades, that's worth understanding.

What isn't a good ground: "The universities we want require A*AA, so we need those predictions." Teachers will (rightly) predict what they think the student can achieve, not what the offer requires.

What to do before autumn

Predictions for UCAS are typically finalised in September or October of Year 13, based heavily on end-of-Year-12 performance. That means the window to influence them is now — the summer term of Year 12 and the summer holiday.

Practical steps:

• Take the end-of-Year-12 mocks seriously. For most schools these are the single biggest input into the prediction. Treat them like the real thing: revise properly, practise past papers under timed conditions, and go over mark schemes.
• Ask each teacher directly what they need to see. A short, polite email or a word after class: "What would I need to demonstrate between now and September for you to be confident predicting an A*?" Most teachers will give a straight answer.
• Use the summer holiday deliberately. Six weeks is enough to close a significant gap in one or two subjects. Focus on weak topics identified in mocks, not general revision.
• Consider whether a subject-specific tutor would help. If the gap between current performance and target grade is real — not imagined — a few sessions over the summer on the specific topics holding your child back can shift a mock grade by the autumn. This is where private tutoring genuinely earns its keep at A-Level: targeted work on weak areas, not general "revision".
• Keep evidence of independent work. Essays written for competitions, EPQ drafts, reading beyond the syllabus. This gives teachers something concrete to point to when justifying a higher prediction.

Having the conversation

If, after all that, you and your child still feel a prediction is too low, request a meeting with the subject teacher — not the head of sixth form, at least initially. Come with specifics: which piece of work, which mock question, what your child thinks they can demonstrate by a given date.

Frame it as: "Here's what we've done, here's the evidence, can we agree what more you'd need to see to move the prediction up?" That's a conversation teachers respect. "We think the prediction is unfair" is one they've heard too many times to engage with productively.

The honest summary

Most predicted grades are broadly right. Some are too cautious, a few are too generous, and a small number are genuinely unfair. The families who end up with predictions that match their child's ability are almost always the ones who took Year 12 mocks seriously, used the summer well, and had honest conversations with teachers early — before the prediction was written down and sent to UCAS.

The time to influence a predicted grade is before it exists. Once it's on the form, it's very difficult to change.
