    This study examined and analyzed the dimensionality of the Nigerian Senior School Certificate Examination Multiple-choice Objective Tests in Government. Exploratory research design was adopted for the study. A representative sample of 1,348 out of 3,034 Senior Secondary School Three (SSS III) students from 49 schools participated in the study through multi-stage sampling technique. The June/July series of NECO Senior School Certificate Examination June/July Multiple-choice Objective Tests in Government for the years 2013 and 2014 were adopted as instrument for the study. Data collected were analyzed using Principal Component Analysis and Proximity Matrix Method of the HCA Approach. The findings of this study revealed that 56 items representing 93.33% of the total of 60 items in NECO SSCE June/July Multiple-choice Objective Tests in Government for the two years were unidimensional and no significant difference was observed between the two tests. In conclusion, the two tests were unidimensional. The study recommended that efforts should be intensified toward improving the standard of the tests items, that all examining bodies using multiple-choice test instruments should be encouraged to use the Hierarchical Cluster Analysis Approach in test development process.

    Mathematics is an essential subject for human existence on day-to-day activities. This is an indication that it if properly handed it could enhance national development. Therefore, in test items construction to examine students’ performance in the subject careful considerations must be given. The purpose of the study is to investigate of student of mathematics multiple-choice test items used for a joint mock examination in Kwara State public schools. The study adopted a descriptive research survey type. The population comprised students in Senior Secondary Schools while the target population consisted of Senior Secondary School II students. The multistage sampling technique that involved stratified, proportionate and simple random sampling was used at different stages of selections. The measuring device was the 2018/2019 Kwara State Joint Mock Mathematics Test. The test is a standardized test and thus the validity and reliability coefficients were not disclosed to the public. The statistical technique employed was factor analysis using. This study, therefore, concluded that only 41 (82%) of 50 multiple-choice items revealed evidence of unidimensionality. One of the recommendations was that those items that violated unidimensionality assumption should be revisited so that instrument could be 100% compliance to unidimensionality.
