This study aims to produce valid and reliable HOTS physics questions based on Borg and Gall development model. The data collection instruments used consisted of questions grids, question sheets, and validation sheets. The data analysis techniques used were item analysis consisting of validity, difficulty level, and discrimination index analysis, and reliability test. The results of this development are 15 valid questions out of 25 items developed. Of the 25 items, 3 items were declared difficult, 20 items had a moderate level of difficulty, and 2 other items were relatively easy. Also, these questions were stated to be reliable through the Cronbach Alpha value of 0.78. The results of this study indicate (1) the instrument is declared valid by the experts with the value of 4.5 and (2) this instrument is declared reliable through the reliability tests on stage one and two respectively with the obtained value of 0.74 and 0.76 which is included in the high-reliability level. Thus, based on the results of the research, the HOTS instrument on fluid material is classified as valid and reliable.
