Abstract:
To ensure validity of student assessment, there should be a positive relationship between the profile of the study content, and the profile of the learning objectives to be tested. This study has indicated that, in the 8 subjects which were analyzed, this relationship varied from a weak positive (r = 0.13), to a strong positive (r = 0.914). It can also be concluded that, depending upon the nature of the subject, 50-70 per cent of questions on the memory level, would be acceptable in a written paper.

The Crown, Neck, and Root
