Note: The Department of Education requires schools to be in session for a certain number of days in a year. To fulfil our quota we need to fit in a number of Saturdays to make up the time. This is common practice amongst all ISASA schools. In particular for 2021 our compulsory Saturdays will include Speech Day, some Saturday exams, team sports’ selection days, Winter Sports Day and two Derby Days. These Saturdays will be announced well in advance so that parents and guardians will be able to make the necessary arrangements.


The High School issue learners with end-of-term reports after each term, and interim reports before the mid-term break.

The Pre-Preparatory School and Preparatory school only issue term reports.

The High and Preparatory School events and key dates are published on the School App.
