All the work of MYP students is internally assessed by teachers using a criterion-related approach. The assessment criteria for each subject correspond to the objectives of a particular subject group. The level of student success in reaching the objectives of each subject group is therefore measured in terms of levels of achievement described in each assessment criterion.
