How does WAEC ensure standardisation in grading?

First, a committee of experts draws up a WAEC grading/marking guide. All appointed examiners are then thoroughly drilled in all aspects of the marking scheme in a simulated marking exercise called co-ordination. Actual WAEC grading/marking does not start until the coordinating officers are satisfied that all examiners know what is required of them. Even when actual marking begins, the examiners are not left entirely on their own. They are organised into small groups, each being supervised by a highly experienced examiner called a Team Leader. The Team Leader checks and vets the group members’ marking progressively to ensure that they are keeping to the WAEC grading guidelines. The Team Leaders themselves are supervised by more experienced examiners called Chief Examiners. When marking is finally completed, WAEC still goes ahead to employ another group of people called Checkers. The main role of Checkers is to ensure that all marks awarded by examiners are correctly recorded and transferred to the appropriate WAEC grading score sheets.
