Critical thinking skills are one of the skills that must be possessed by students as graduate competency standards. Instrument evaluation is needed to evaluate critical thinking skills. This study aims to examine the quality characteristics of multiple choice test instrument items to measure critical thinking skills. The test instrument developed was an Electrical Instrallation Automation test instrument in order to maintain the quality of critical thinking test instruments with the addition of a wider variety of reasoning aspects. The test instrument is in the form of multiple choices which have analysis questions (C4), synthesis (C5), and evaluation (C6). The method of developing research uses the Research and Development (R & D) method. The object of the research was all the answers to the results of the tests of 40 Electrical Engineering students. Data is collected by the method of observation, interview and documentation. Data analysis techniques are qualitative and quantitative using the Test Analysis Program (TAP) application. The results showed that: The instruments developed had good characteristics in terms of validity with the Aiken index content validity (Aiken V) of 0.820 and reliability coefficient of 0.843 in a good (reliable) range. Furthermore, for the difficulty level of 0.560 in the medium category, the average differentiation of 0.333 can be categorised as good and the results of the analysis of the distractor quality are 39 tests that function well. © Primrose Hall Publishing Group.
