Abstract

The study established if 2016 NECO Mathematics multiple choice test items satisfy unidimensionality and local independence assumptions of Item Response Theory; and it determined the nature of item characteristics curve in the 2016 NECO mathematics items. Ex-post facto design was adopted for the study. The population for the study comprised candidates who enrolled and sat for June/July SSCE 2016 NECO Mathematics Examination. The sample comprised 276,338 candidates from three purposively selected Geo political zones in Nigeria. The results showed that the 2016 NECO Mathematics test was essentially unidimensional. However, nine of the items are interdependent on each other. Also, the results revealed that 12 items do not produce a monotonically increasing function in the form of forward S shape for the probability of correct response recommended for good item under IRT.
