Higher Order Thinking Skills (HOTS) are part of the 21st-century skills that are important for everyone, including prospective Physics teachers. Prospective Physics teachers must have HOTS as stated in the learning outcomes. The achievement of HOTS for prospective physics teachers is carried out through an assessment. Assessment can describe the actual ability of a good instrument that is valid and reliable. The study aimed to analyze the validity and reliability construct of the Fundamental Physics Higher Order Thinking Skill (FundPhysHOTS) test instrument. This study is a descriptive study applying a quantitative approach. The data used in this study were student responses to the FundPhysHOTS test instrument. The test instrument is Two-Tier Multiple Choice (TTMC) with a polytomous score of 4 categories score (1,2,3 and 4). The research subjects were 264 prospective physics teacher students consisting of 148 prospective physics teachers at one of the universities in West Java province and 116 prospective physics teachers at universities in Banten province. Data analysis using Confirmatory Factor Analysis (CFA). The results indicated that most of the items developed had good construct validity (with a loading factor (λ) value more than 0.4). It means that the items developed are valid in measuring the HOTS of prospective teacher students. The construct reliability of this test instrument belongs to the reliable category (reliability construct coefficient value 0.514, more than 0.5; and Cronbach Alpha value is 0.86, more than 0.80), which means it has good consistency and stability. © 2023 Author(s).
