Abstract :
The purpose of the research was to see the level of validity, reliability, index of difficulty, and differentiating power of student test questions. The research population were 28 students majoring in Automotive Engineering of UNP. The research sample was selected using a total sampling technique, so that the entire population became the research sample. Data collection techniques used documentation in the form of giving and collecting test questions; answer key; and the answer sheet for the test. Data analysis used quantitative descriptive analysis techniques. The results of data analysis will produce levels of validity, reliability, index of difficulty, and differentiating power of test questions. The results of the data analysis concluded that the test items were in the valid category, the reliability index of the questions on the criteria of high reliability, the difficulty index with the category of good/decent items, and the discriminating power of the items including the good classification of questions. Based on the results of the research, it was concluded that the test questions given to students deserved to be used as a test to measure students' cognitive abilities.
