Abstract
The study sought to estimate item parameter indices of NECO Senior
School Certificate Economics multiple choice items in
Delta State. Four research questions guided the study. This
study adopted ex-post facto research designs. The
population of this study comprised 66,632 Senior Secondary three (SS3) students
in Senior Secondary Schools in Delta State. The sample consisted 677 using
multi-stage procedure was used. The instruments for data collection were National
Examinations Council (NECO) Senior School Certificate Economics 2022 and 2023
Multiple Choice Items which contain 60 items each for the two years. The
researcher used Kuder-Richardson 20 formula to estimate the reliability of the
instruments and a coefficient of .73 and .77 for 2022 and 2023 respectively
were obtained as measures of internal consistency. Data were analysed using the
Raju Area estimation technique of BILOG-MG software to determine the item
parameter indices. Frequency count and percentage (%) were used to answer the
research questions while chi-square statistics was used to test the hypotheses
at 0.05 alpha level. The findings revealed that the NECO SSCE 2022 and 2023
Economics multiple choice tests contain items that have good discrimination
indices, difficulty indices, guessing indices and distraction indices. Based on
the finding, it was recommended that NECO SSCE Economics multiple choice
questions that is constructed should be pilot tested every year to ensure that
only items that fail should be either modified or discarded and the assistance
of measurement and evaluators should be sought by NECO during item development
to enhance fairness of test items.
