With the purpose of the test, the field examination resulted in the preparation of a material pool consisting of 25 already selected questions. For the purpose of ensuring the scope and appearance of the test, the expert opinion has been applied and 20 material draft tests have been created. The pilot application of the draft test was carried out with 24 students. The material analysis after the pilot application determined the average matter difficulty index (pj=.57) and the average matter differentiability index (rjx=.50). The reliability of the test is calculated by the KR-21 reliability ratio (.741). The findings of the study show that the "Simple Machinery Unit Academic Success Test" is a valid and reliable test consisting of 18 already selectively asked questions.
