The centre is responsible for designing the written assignments, which are not to be less than a total of 3000 words. The assignments are internally assessed and externally moderated. The Certificate will be awarded to candidates who meet the course requirements and whose performance meets, or exceeds, the criteria in all three assessment components. A Pass is awarded to candidates whose performance overall in the teaching practice and in the written assignments meets the specified criteria. An individual report, which includes details of the candidate's performance and achievement, is produced for each candidate by the centre.
Every course is moderated by an external assessor.
Every centre is allocated a Joint Chief Assessor who monitors standards at the centre. Standardisation meetings for centres, assessors and Joint Chief Assessors are held annually.
