The purpose of this study is to develop a three-level multiple choice assessment instrument to measure critical thinking skills of students at SMA Negeri 5 Bengkulu City on thermochemical material. The development model used is the ADDIE model. The research subject is class XI MIPA 4 at SMA Negeri 5 Bengkulu City in the academic year 2022/2023.
