The study compared the difficulty and discrimination indices of the Pre-University Tertiary Matriculation Examination (Pre-UTME) and Post-University Tertiary Matriculation Examination (Post-UTME) in the related subject areas of Arts, Commercial and Science in Obafemi Awolowo University (O.A.U.), Ile-Ife, Nigeria. The study adopted the exploratory survey research design. The population for the study comprised all part one undergraduate students of the O.A.U., Ile-Ife in 2013/2014 session. While simple random sampling technique was used to select 40 departments, convenience sampling technique was used in drawing 20 part one undergraduate students from each of the 40 departments. A 20-item achievement test titled: 2013/2014 Pre-UTME and its corresponding 2013/2014 O.A.U. Post-UTME were instruments used for collecting data for this study. Data collected were subjected to item analysis. Results revealed that the items of the O.A.U.’s 2013/2014 in the subject areas of Arts, Commercial and Science (with average difficulty indices, p, of 0.53, 0.46 and 0.55 respectively) were more difficult than items of the 2013/2014 Pre-UTME in the same subject areas (having average p of 0.62, 0.54 and 0.60 respectively). Finally, the results revealed that the items of the 2013/2014 Pre-UTME and O.A.U.’s Post-UTME in the subject areas of Arts, Commercial and Science discriminated appropriately between students in the high scoring group and those in the low scoring group with average discrimination indices of 0.45, 0.43, 0.46 and 0.46, 0.43, 0.42 respectively.
