Delegates at the Alberta School Boards Association meeting today passed a motion to have diploma exams worth 30 per cent of a final grade.
For the past three decades diploma exams in Alberta have been worth 50 per cent of a student's final mark.
Edmonton Public School Board chair Sara Hoffman says the change is overdue.
Hoffman says marks under the new system will better reflect students' knowledge.
The association will now call on the province to approve the change.
