IB Diploma Requirement Calculator (2025)
Use this tool to estimate whether a student meets common IB Diploma award requirements: six subjects (1-7), HL/SL split, core points (TOK + EE), and CAS completion.
Note: This calculator is an informational guide, not an official IB decision tool. Always confirm results with your IB coordinator and school policy.
What this IB calculator is for
If you are searching for ib calculator requirements 2025, you probably want a quick way to answer one question: “Am I on track for the IB Diploma?” This page gives you a practical checker for common diploma award rules, plus an explanation of what each rule means in plain language.
It is especially useful for students working with predicted grades, mock exam data, or end-of-term reports. Teachers and parents can also use it to identify risk areas early, before final exams.
Core requirement categories checked by this tool
1) Total points threshold
The calculator combines six subject grades (maximum 42 points) and core points from TOK + EE (maximum 3), for a total out of 45. A common minimum diploma threshold is 24 points.
2) HL and SL performance minimums
A valid IB Diploma pattern must include higher-level and standard-level subjects. This calculator checks:
- 3 HL subjects: HL total should be at least 12
- 4 HL subjects: HL total should be at least 16
- 3 SL subjects: SL total should be at least 9
- 2 SL subjects: SL total should be at least 6
3) Low-grade limits
The tool checks score-profile conditions commonly used to determine diploma eligibility:
- No grade 1 in any subject
- No more than two grades of 2
- No more than three grades of 3
- No more than three grades of 2 and 3 combined
4) Core and CAS completion
Beyond exam points, diploma success also depends on core completion and school confirmation of CAS. In this calculator, CAS must be marked complete, and core points must be entered from 0 to 3.
How to use the calculator effectively
- Enter your latest realistic grades, not “best-case” guesses.
- Set HL/SL exactly as registered with your school.
- Recalculate after each assessment cycle to track trend direction.
- Use the failure reasons section to decide where to improve first.
A smart strategy is to run three scenarios: conservative, expected, and stretch. This gives a clearer risk map than a single score estimate.
Example planning scenarios
Scenario A: Strong pass profile
Subject total 30 + core 2 = 32. HL sum 16 (with 3 HL subjects), SL sum 14, no very low grades. This profile generally clears all major checks comfortably.
Scenario B: Borderline profile
Subject total 22 + core 2 = 24. If this student also has multiple low grades at HL or too many 2s/3s, they can still miss diploma requirements despite hitting 24 total points.
Frequently asked questions
Is this an official IB calculator?
No. It is an educational tool designed to mirror commonly used diploma checks. Official outcomes are determined by IB and your school.
Can school policies add extra rules?
Yes. Schools may enforce internal progression standards, predicted-grade policies, or intervention thresholds that are stricter than minimum diploma conditions.
What should I do if I fail one condition?
Prioritize high-impact fixes first: raise HL total, remove grade 1 risk, and improve any 2/3 concentration. Then re-run the calculator to verify your new pathway.
Final note for 2025 candidates
The best use of an IB requirements calculator is not just pass/fail checking; it is early decision support. Start early, update often, and use your results to guide revision time, IA priorities, and support conversations with teachers.
