Earning the IB Diploma

Each IB subject is assessed on a scale of 1 – 7 with a score of 4 considered a “passing grade”. This score is calculated based on a combination of internal and external assessments throughout the 11th and 12th grade years. A total of six subjects must be studied, with a combination of standard and higher levels (SL and HL). Students must also complete the “core”, which is made up of creativity, activity, service (CAS), theory of knowledge (TOK) and extended essay (EE). TOK and the EE are graded on a scale of A-E.

To earn the IB diploma, students must score a minimum 24 out of a possible 45 points and earn at least a 'D' for both TOK and the EE.
