ESTABLISHING CONSTRUCT AND CONCURRENT VALIDITY OF UNIVERSITY OF IBADAN POSTUTME ON MATHEMATICS PAPER

Abstract

The study was carried out to establish a construct and concurrent validity test of Post-UTME Mathematics 
paper for prospective prelim students at university of Ibadan. Two research questions were drawn to guide the 
establishment of construct and concurrent validity test of Post-UTME Mathematics paper. It is a multiple choice 
objective test of four options with 100 items. A sample of 358 applicants was randomly drawn to determine the 
construct and concurrent validity of the test. After item analysis, the result showed that the Post-UTME 
Mathematics test has a high face and content validity. The test item validity was determined through the grades 
made in SSCE conducted by either WAEC or NECO, the score obtained in Mathematics by individual candidate 
in UTME conducted JAMB and the score obtained in Mathematics in Post-UTME conducted by the University of 
Ibadan. The SSCE results was manipulated by converting A1 = 87.5, B2 = 72, B3 = 67, C4 = 62, C5 = 57, C6 = 
52, D7 = 47 and E8 = 42 in percentages to equate SSCE to scores in UTME and PUTME respectively. The test 
has a construct and concurrent validity coefficient of 0.623 established through the use of Pearson Product 
Moment Correlation tool. The test is valid and reliable for assessing student‘s ability and capability to gain 
admission in to university of Ibadan and can be used for selection in to any higher institution in Nigeria.
