Abstract
The study assessed item parameter drifts across
school type in WAEC Mathematics examination 2018-2019. Two research questions
guided the study and two hypotheses were tested. The study adopted a
descriptive survey research design. The population consisted all the 49,742 SS3
students from the 292 public and 182 Government approved private secondary
schools that enrolled for 2022/2023 Senior School Certificate Examination of
West African Examination Council (WAEC) in Enugu State totaling 474 schools. A
sample of 820 SS3 students from 10% of the 474 schools approved to write WAEC
in Enugu State were selected through multistage sampling. The 2018, 2019 and
2020 WAEC mathematics multiple choice examination questions were adopted as
instruments for the study. The instruments did not pass through validation and
reliability as they were already good questions used by WAEC. Bilog MG software
was used to answer the research questions while Analysis of Variance (ANOVA)
was used to test the null hypotheses at 0.05 level of significance. The
findings of the study among others showed that among the 50 items, eleven items
were deemed to have drifted significantly in the distributions of item
difficulty indices of 2018 mathematics multiple-choice tests based on school
type among the examinees. The study recommended among others that West Africa
Examination council should ensure that as items are re-used or repeated,
response parameter must be updated and made more accurate to stated criteria
before use.
