TOK assessment
The calculator separates the TOK essay and TOK exhibition. The essay contributes approximately two thirds of the final TOK result and the exhibition approximately one third. Their weighted result is converted to a TOK letter grade from A to E using the configured boundary set.
Extended essay assessment
The extended essay is marked against its assessment criteria and converted to a letter grade from A to E. It does not add points directly according to its raw mark; the TOK and EE letters are combined through the core matrix.
Core points matrix
| EE \ TOK | A | B | C | D | E |
|---|---|---|---|---|---|
| A | 3 | 3 | 2 | 2 | Failing condition |
| B | 3 | 2 | 2 | 1 | Failing condition |
| C | 2 | 2 | 1 | 0 | Failing condition |
| D | 2 | 1 | 0 | 0 | Failing condition |
| E | Failing condition | Failing condition | Failing condition | Failing condition | Failing condition |
For example, a TOK grade of B combined with an EE grade of C produces two core points. Two strong letter grades do not always produce the maximum three points, which is why the matrix matters.
CAS is different
Creativity, activity, service is part of the Diploma core but receives no letter grade and contributes no numerical core points. It must still be completed. The calculator marks CAS as complete for planning purposes; this is an assumption, not school confirmation.
What students should check
- Use the correct TOK and EE grade boundaries for the relevant session.
- Do not confuse an individual component percentage with the final letter grade.
- Treat an E in TOK or EE as a serious Diploma award condition.
- Confirm final core outcomes through the school and official results.
