Programming is to produce computer-based solutions for a problem by situation analysis, algorithm and program design, implementation, testing and debugging. It is usual situation that encounter bugs in the programming process. The process of resolving the bugs and making the generated program codes free of bugs is called debugging. Debugging requires deeper knowledge than writing new code. Debugging is a skill that programmers must acquire, like good coding and write efficient code. In the literature, there is a lack of a valid and reliable measurement tool for the evaluation of debugging performances. In this study, it is aimed to develop an achievement test in order to evaluate the debugging performance of students studying in the Information Technologies departments of vocational high schools. During development of the test, the purpose of the test, the bugs encountered and their scope were determined, related literature reviewed, the test consisting of 27 code scenarios was created and expert opinion was obtained to ensure content validity. After expert opinions and pre-pilot implementation, 18 code scenarios were determined for pilot implementation. 148 students from different vocational and technical high schools in the Information Technology Department participated in the pilot implementation of the test. According to the analysis carried out for the test and the items, the necessary items were removed. As a result, the item difficulty indexes are between .30 and .49, the item discrimination indexes are between .39 and .69, and the item reliability indexes are between .20 and .33 in the test. Also, the KR-20 reliability index of test is .575. Therefore, it can be said that The Debugging Performance Test is valid and reliable.
