There have been many criticisms about the low performance of students in mathematics by the examinations conducted by the West African Secondary School Certificate Examination (WASSCE). Comparing the performance of students in mathematics in the district to their performance in the WASSCE leaves some discrepancies. This study, therefore, examined the distracter efficiency and reliability coefficient of teacher made achievement test of senior high schools in Ghana . The research design adopted for the study was a descriptive survey. Purposive sampling was used to select the school for the study. The data was gathered from an adopted teacher-made test developed from the mathematics syllabus of the Ghana Education Service by the teachers. The fifty items were randomly sampled from the previous (2018-2021) end-of-term mathematics test of Brakwa Senior High and Technical School teachers. Kuder Richardson version 20 (KR20) statistics was used to check for the reliability of the study instrument and percentages for the functional distractors and non-functional distractors. The finding revealed that out of fifty (50) items, 38 were good, and 12 were poor as indicated by the distracter efficiency. It could be concluded from the findings that generally the distractor and reliability analyses result of the teacher-made test of Brakwa Senior High and Technical in mathematics was better. It was recommended that heads of the mathematics department of Brakwa Senior High and Technical School should organise more in-service training on item analysis for mathematics teachers to upgrade and improve their test construction skills.
