Concurrent Validity of the Twelfth Grade Internal Examinations

This study examined the concurrent validity of the teacher-made tests taken by 1794 Grade 12 students using raw scores on an external examination conducted by the Kenya National Examinations Council. Although internal examination scores were significantly correlated with scores on the standardized achievement test, the Kenya Certificate of Education, there were significant mean differences among schools. The data provide evidence for the validity of the internal examination as a measure of the same abilities as the Kenya Certificate of Education examination. Implications of this concurrent validity with respect to the quality of the school and the objectivity of the teachers' evaluation were discussed.
