EQUIPERCENTILE EQUATING OF WAEC, NECO AND NABTEB SENIOR SCHOOL CERTIFICATE MULTIPLE CHOICE TEST ITEMS IN ECONOMICS

DORCAS S DARAMOLA, HENRY O OWOLABI, ADEKUNLE T OLUTOLA

Abstract


This study investigated equipercentile equating of WAEC (West African Examinations Council), NECO (National Examinations Council) and NABTEB (National Business and Technical Examinations Board) Senior School Certificate Multiple Choice Test Items in Economics. A Non-Equivalent Groups Anchor Test (NEAT) design of test score equating was adopted for the study. Sample for the study consisted of 1,119 senior secondary three students drawn from 30 selected secondary schools in Kwara State through multi-stage sampling technique. The 2009 WAEC, NECO and NABTEB SSCE multiple-choice Economics papers were adapted and used for data collection. Coefficients of content validity of 0.67, 0.64, and 0.60 as well as reliability of 0.79, 0.67 and 0.70 were obtained respectively. Data collected were analyzed using means and Percentiles. Findings of the study revealed that respondents’ performance on the common items of WAEC, NECO and NABTEB were not different (π‘‹π‘Šπ΄= 1 0.98; 𝑋 𝑁𝐸=11.30; 𝑋 𝑁𝐴 =11.28) and respondents performed differently in unique items across the test forms ( π‘‹π‘Šπ΄=35.45 < 𝑋 𝑁𝐸=36.40 < 𝑋 𝑁𝐴= 41.54). In addition, the finding showed that score of 54 in WAEC was equivalent to 57 and 60 in NECO and NABTEB respectively which corresponded to the percentile rank of 93. Based on these findings, the researchers recommended that equating method with lower coefficient of variation should be employed for equating scores by examining bodies in Nigeria and a regulatory body to standardize and monitor examinations conducted by the examining bodies should be established in Nigeria.
