Written reports are seen as a summative record for students, parents and the school itself of a student’s progress. Nonetheless, the formative potential of an effective reporting procedure should not be overlooked. Reports that clearly indicate areas of strengths, areas for improvement, and where students are involved in providing input (through self-assessment), are helpful aids to a student’s development.
The reporting system and procedures of a PYP school reinforce the underlying values of the programme.
