The quiet moment your IB predicted grade is decided
It usually doesn’t happen in a dramatic meeting with a gavel.
Your IB predicted grade is more often decided in ordinary moments: a timed response where you finally used the command term correctly, a mock where your pacing fell apart, an IA draft that showed real control of criteria, or a month of steady, boring improvement that a teacher can trust.
For IB students preparing for exams, predicted grades can feel like a verdict. For teachers, they’re closer to a well-supported estimate: a number built from what they can prove you’re likely to do under exam conditions.
This guide explains when predicted grades are produced in the IB, how they’re predicted, and what students and parents can do next.
Predicted grades in IB: a simple checklist
If you want the fast version before the details, here’s the predicted-grade checklist that fits most IB schools:
-
Predicted grades are teacher estimates of your final IB subject grades (1--7), plus a prediction for TOK/EE core points (0--3).
-
They’re usually finalized in DP2 to meet university timelines.
-
Teachers rely most on recent, exam-like evidence: mocks, timed tests, structured writing, problem sets.
-
Coursework progress (especially IA quality) can move a prediction when it shows clear criterion alignment.
-
Predictions can sometimes change before submission, but rarely after they’ve been sent to universities.
To sanity-check your trajectory, you can use the IB Grade Calculator to convert practice performance into a realistic diploma-points estimate.
When are predicted grades predicted in the IB?
In most IB Diploma Programme schools, predicted grades emerge in two phases.
Informal signals in DP1
By the end of DP1, some schools share informal indicators in reports or meetings. These are not always the “official” predicted grades, but they shape expectations. DP1 trends matter because teachers are trying to answer a simple question: is your performance stable, improving, or inconsistent?
Official predicted grades in early DP2
The official predicted grade window is commonly September to October of DP2 for many May-session cohorts, because that’s when early university deadlines start to bite. UK applications through UCAS (especially competitive routes like Oxbridge/Medicine) often require references and predictions by mid-October, while many US early rounds land around November.
Some schools will revise or confirm predictions later for regular admissions rounds, but the key idea in IB is this: predicted grades are designed to be ready before final exams, because universities need an academic signal while you’re still mid-programme.
If you’re planning your preparation, it helps to pair that timeline with exam-style practice. Tools like RevisionDojo’s Predicted Papers and targeted drilling in the Questionbank help you create the kind of evidence teachers actually use.
How teachers predict grades in IB (what they actually look at)
In the IB, predicted grades aren’t meant to be vibes. Teachers have to justify them, often to department heads and coordinators, and they usually lean on four evidence buckets.
Mock exams and timed assessments (usually the biggest driver)
Mocks replicate the two things predictions care about most: time pressure and markscheme logic. A student who knows content but collapses under timing risk is hard to predict generously.
This is why running realistic practice matters. RevisionDojo’s ecosystem is built around that loop: Mock Exams for timed rehearsal, Grading tools for learning how marks are awarded, and AI Chat for quick clarification when a mistake pattern won’t leave you alone.
Class tests, quizzes, and everyday consistency
Teachers look for repeatability. One great test can be noise. Four solid assessments across a term look like signal. In the IB, consistent performance also suggests you’re mastering the method, not just memorising isolated facts.
Internal Assessments (IAs) and coursework progress
IAs are internally marked and externally moderated, so they matter. A strong draft that clearly meets criteria can improve a teacher’s confidence in your final grade potential.
If coursework is stressing you out, RevisionDojo’s Coursework Library and Tutors are built for exactly this moment: reduce uncertainty, get feedback, and keep your effort aligned to rubrics rather than panic.
Professional judgement and standardisation
Most departments run standardisation conversations: comparing boundaries, discussing what “a 6” looks like in practice, and aligning across classes. That protects fairness, but it also means teachers may be careful about inflation.
For students, the takeaway is simple: in the IB, you improve a prediction by improving the quality and visibility of evidence.
How predicted grades are used (and why they feel so high-stakes)
Predicted grades are central to university admissions systems that make decisions before final results.
-
In the UK, predicted grades often drive conditional offers (for example: “38 points, including 6 in HL Biology”).
-
In other systems (including many US holistic reviews), predicted grades support the narrative of academic readiness alongside transcripts and school context.

Can predicted grades change in the IB?
Yes, sometimes. But the “sometimes” has rules.
-
Predictions can change before the school’s submission deadline if new evidence arrives (a later mock, a major assessment, a strong IA improvement).
-
Some schools allow an appeal process, but it’s typically evidence-based and time-limited.
-
Once predictions have been sent out in references or submitted, changing them is rare and usually requires exceptional circumstances.
If you’re trying to improve, it’s more effective to ask: “What evidence would change your mind?” than “Can you raise it?” That frames the conversation in a way that matches how IB teachers make decisions.

How to improve your predicted grades (the evidence loop)
The fastest improvements in IB usually come from shrinking the gap between “I understand this” and “I can do this in 80 minutes.” Here’s a calm, repeatable loop:
Build clarity
Use syllabus-aligned explanations first so you’re not practising confusion. (This is where RevisionDojo Study Notes earn their keep: short, targeted, exam-focused.)
Build recall
Daily Flashcards keep the forgetting curve from eating your weekend. Ten minutes a day beats a three-hour burst you can’t repeat.
Build exam performance
Do targeted sets in the Questionbank, then review mistakes like a scientist: classify the error (content gap, command term, calculation, structure, misread question), fix it, and retest within 48 hours.
Build realism
Use Predicted Papers as a rehearsal tool, not as prophecy. They’re valuable because they simulate the decisions you’ll make under pressure.

The bottom line for IB students and parents
Predicted grades in the IB are snapshots taken under constraints: limited time, partial coursework completion, and imperfect information. They still matter because universities need a signal before results day. But they’re also changeable in one practical way: you can improve what they’re based on.
If you want your IB predicted grades to rise, focus on evidence that looks like the real exam: timed practice, corrected mistakes, and consistent performance. Build that system once, and it helps everywhere.
Start by checking your current baseline with the IB Grade Calculator, then run your improvement loop inside RevisionDojo using Study Notes, Flashcards, Questionbank, AI Chat, Grading tools, Predicted Papers, Mock Exams, the Coursework Library, and Tutors when you need human feedback. That’s how a prediction becomes a plan in the IB.
