Academic Standards

Our assessment scheme records progress on a scale from 7 (Excellent) to 1 (Very Poor/Insufficient). Please see Portaria 433/2005, April 19th for equivalence. A student is at risk of failing the year if they achieve a 3 or below in three or more MYP or DP subjects (all subjects are included).

Achievement grades of 3 or less should be viewed as failing grades or at least indicating lack of readiness to proceed to the subsequent year’s study.

In MYP, a grade 2 in the Personal Project (PP) or non-completion of Service As Action is viewed as failing conditions.

In IB-DP, non-completion of DP subject Internal Assessments, Extended Essay (EE) or Creativity, Action and Service (CAS) are also viewed as failing conditions.
