COMPARATIVE ITEM ANALYSIS OF STUDENTS’ WAEC AND NECO MATHEMATICS OBJECTIVES TEST ITEM SCORES
The purpose of this study was to compare psychometric properties of students’ WAEC and NECO Mathematics objectives test item scores. Two null hypotheses were formulated to direct the study and literature was reviewed on the variable under study. The research design used was the Ex-post facto (causal comparative) design. A total sample of 250 SS 3 students was selected using stratified random sampling procedure from 10 senior secondary schools for the study. Data collected for the study was done using WAEC and NECO SSCE Mathematics multiple choice papers of 2011. The collected data was analysed using the independent t-test statistics. The result of the data analysed showed that item difficulty index and discrimination index of WAEC significantly differ from that of NECO in terms of items. Based on these findings, it is recommended that proper investigation should be conducted by experts to determine the causes of variations between WAEC and NECO examination from the development stage, administration, scoring of scripts and to the release of results.
