    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.
