Evaluation in the IB Diploma Programme

The IBO does not change grades (i.e. bell curve) in order to establish a particular percentage of candidates within a mark category. Therefore, the student’s achievement is assessed according to his/her within own ability in regards to the criteria specified within each subject group area. Assessment in each subject consists of some or all of the following:

External Assessment:

• Written examinations based on part or on the entire course syllabus
• Oral examinations that are tape-recorded and externally assessed by an IBO examiner or conducted by a visiting examiner.

Internal Assessment:

• The task evaluation details vary between subject groups. However, all aspects of internal assessment, initially marked by the teacher in charge, will be externally verified and amended by IBO moderators to ensure uniform standards are being met.

Most subjects have an internal assessment component though the majority of the subject grade is carried out via external assessment.
