Mathematics Learning Achievement Test (MLAT)This was made up of thirty one (31) multiple choice items with four options. All the questions are to be answered by the participants within an hour. The reliability coefficient of the instrument was determined using Kuder – Richardson formula 20 (KR20). Kuder – Richardson formula 20 (KR20) was used to determine the internal consistency and overall coefficient of the instrument. Item analysis was also used to carry out the difficulty index and discriminatory power of the test. This was done between the higher achievers and lower achievers in Mathematic. The difficulty and discriminating indices of each of the test items was computed for further validation of the instrument. The difficulty level of .51 and the discrimination index of .75 were obtained.
