Abstract
The purpose of this research is to design a test instrument based on high-order thinking skills with culture context on the topic of geometric transformations that can be used to measure this ability. The research was conducted based on the Plomp model which consisted of three phases: (1) preliminary research, (2) prototyping, and (3) assessment. The subjects of this study were students of class IX Alhijrah 2 in Deliserdang Regency. The results showed that the HOTS-based test instrument on the topic of geometric transformation met the Nieveen quality standard, which consisted of valid, practical and effective criteria. Five validators stated that the instrument was valid in terms of language, content, and construct, with each category being very valid. This intervention product was also practical, this means that the test instrument was easy to use by students and teachers. In addition, the test instrument was effectively used to measure students^ high-level mathematical thinking abilities.
