How to interpret IB grades and transcripts

A student's examination performance in individual subjects is scored on a scale of 1–7 points with a further 3 points available based on a matrix of performance in the theory of knowledge (TOK) and the extended essay components. Students who display satisfactory levels of performance across all subject areas and achieve a minimum of 24 points (out of a possible 45) are awarded the IB diploma. All others receive a certificate of results for the subjects examined. Subjects are marked according to the following scale.

7 Excellent
6 Very good
5 Good
4 Satisfactory
3 Mediocre
2 Poor
1 Very poor
N No grade

The TOK course and the extended essay are graded according to the following scale.

A Excellent
B Good
C Satisfactory
D Mediocre
E Elementary
N No grade

Examination results are available in early July following the May examination session, and in early January following the November examination session. If requested by the student, results are made available to universities either in electronic format or as a transcript of grades, as appropriate. The results indicate the grade a candidate has been awarded for each subject, including the additional diploma requirements of theory of knowledge and the extended essay. The results also indicate the completion of creativity, action, service (CAS) and total number of points for the diploma, if a diploma has been awarded. Diploma awarded, Bilingual diploma awarded or Certificate(s) awarded will appear on the results.

Bilingual diplomas are awarded for:

  • two languages A1, or
  • a language A1 taken together with a language A2, or
  • a group 3 or 4 subject taken in a language other than the candidate's language A1, or
  • an extended essay in a group 3 or group 4 subject written in a language other than the candidate's language A1.
