Gaining the Diploma  

Each examined subject is graded on a scale of 1 (minimum) to 7 (maximum). In order to be awarded the diploma, a student must gain a minimum total of 24 points and the satisfactory completion of the three diploma requirements: TOK, the extended essay, and CAS activities. The minimum score of 24 is based on the notion that a grade 4 represents a passing level in each of the six subjects. (Other specific rules apply, such as no HL subject can be lower than a grade 4.) Excellent performance in all of the six subject areas results in a total of 42 points (7 points for each subject). The maximum diploma point score is 45. TOK and the extended essay contribute to the overall score through a matrix system  (below) which awards up to three points based on the candidate’s combined performance.

The quality of work in both TOK and the essay is measured against assessment criteria, and the results are described according to the following five categories: elementary, mediocre, satisfactory, good and excellent.
