ZIMSEC announced significant updates to the CALA framework for 2025 and beyond. On 27 February, ZIMSEC revealed that Continuous Assessment Learning Activities (CALA) have been replaced by School-Based Projects as part of the new Heritage-Based Curriculum Assessment Framework, effective from November 2025.
The new assessment approach integrates both Continuous Assessment (CA) and Summative Assessment (SA), with School-Based Projects contributing 20% to the final year mark, while the Summative Assessment will account for the remaining 80%.
Two School-Based Projects will be conducted for students during Grade 6 and Grade 7, Form 3 and 4, and Form 5 and 6. Each project will contribute 10% to the final mark, with the total contribution being 20%.
In addition, CALA marks that have been banked from previous years will remain valid for a maximum of six examination cycles, providing a window for repeating candidates to use their earlier marks for re-sits:
- 2022 CALA marks: Valid until June 2025
- 2023 CALA marks: Valid until June 2026
- 2024 CALA marks: Valid until June 2027
However, CALA marks from 2021 have reached their expiration date and will no longer be valid. Repeating candidates are encouraged to make use of their valid, banked CALA marks within the stipulated time frames.
This transition aims to phase out the CALA system while ensuring a smooth integration of School-Based Projects, which will form part of the new assessment model, blending Continuous and Summative Assessments.
