IB Coursework, Exams & Grading

Grading Scales

All IB Diploma Programmes require students to complete mandatory and varied internal assessment (coursework) alongside formal examinations at the end of their second year. The IB who awards the final grades by assessing both the internal assessments and final exams.

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 and 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. Subjects are marked according to the following scale.

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

The Core Points Matrix

The performance of a student in both Theory of Knowledge (TOK) and the Extended Essay (EE), is determined according to the quality of the work, based on the application of the IB Diploma Programme assessment criteria. It is described by one of the band descriptors A–E. Using the two performance levels and the diploma points matrix, a maximum of three diploma points can be awarded for a student’s combined performance.

A student who, for example, writes a satisfactory extended essay (C grade) and whose performance in theory of knowledge is judged to be good (B grade) will be awarded 2 points, while a student who writes a mediocre extended essay (D grade) and whose performance in theory of knowledge is judged to be satisfactory (C grade) will be awarded 1 point. The award of zero additional points does not constitute a fail in either TOK or EE as it only refers to the bonus points available in the overall diploma.

A student who fails to submit either an Extended Essay, TOK essay, or who fails to make a TOK presentation, will be awarded an N, will score no points, and will not be awarded an IB Diploma.

Performance in both theory of knowledge and the extended essay of an elementary standard (E grade) is an automatic failing condition for the award of the diploma.

How does assessment work?

The maximum total marks available for an IBDP student are 45. Each of the six subjects are given a final mark out of 7 meaning that a total of 42 is available for subjects areas, whilst a total of 3 marks is given for the EE and TOK assessments combined. Each subject area has between 20-35% coursework that is internally marked and externally moderated. The remainders of the marks, constituting the final examinations, are externally marked.

Generally, a student needs to achieve a minimum of 24 marks to receive their Diploma and must successfully complete all three elements of the core.


The following conditions constitute an automatic failure to achieve the full IB Diploma:

  1. CAS requirements have not been met.


  1. Candidate’s total points are fewer than 24.


  1. An N has been given for theory of knowledge, extended essay or for a contributing subject (usually as a result of academic malpractice or failure to submit work).


  1. A grade E has been awarded for one or both of theory of knowledge and the extended essay.


  1. There is a grade 1 awarded in a subject/level.


  1. Grade 2 has been awarded three or more times (HL or SL).


  1. Grade 3 or below has been awarded four or more times (HL or SL).


  1. Candidate has gained fewer than 12 points on HL subjects (for candidates who register for four HL subjects, the three highest grades count).


  1. Candidate has gained fewer than 9 points on SL subjects (candidates who register for two SL subjects must gain at least 5 points at SL).


A maximum of three examination sessions is allowed in which to satisfy the requirements for the award of the IB Diploma.
