Abstract
This study developed a knowledge assessment instrument of three tier diagnostic tests based on higher order thinking skills (HOTS) which aims to diagnose students' understanding in higher-order thinking and reduce misconceptions. The research method uses ADDIE (Analysis-Design-Develop-Implement-Evaluate) and the subject is class VII junior high school students with 2017 odd semester curriculum materials. This study used HOTS-based knowledge assessment instruments of three tier diagnostic tests of 20 items. The results of the instrument expert validation test based on aspects of content, construct, and language assessment have an average score of 90, 88, and 89 with a proper assessment. The data were analyzed using rasch model and the item reliability index was 0.89, the reliability index of the respondents was 0.91, and Cronbach's alpha value was 0.93, which meant the reliability of the questions obtained was good. The results of the students 'answer patterns are six criteria: understanding concepts, misconceptions (+), misconceptions (-), misconceptions, guessing / lack of confidence / luck, and not understanding the concepts used to diagnose learners' understanding in measuring high-level thinking skills (HOTS) which is integrated with the dimensions of factual, conceptual and procedural knowledge. Misconceptions that occur in students have three criteria, namely misconception (+), misconception (-), and misconception, and the most experienced by students is a misconception (-) in the C4 cognitive level which is integrated with the conceptual knowledge dimension on the substance characteristic material . This misconception (-) can be reduced through the correct concept with the right reasons.
Highlights
The thinking ability of Indonesian students can be illustrated from the results of the PISA 2015 test and evaluation [1]

Based on the student's answer pattern, the teacher can diagnose students' understanding through the knowledge assessment instrument of three-tier diagnostic tests based on HOTS that have been developed
Summary
The thinking ability of Indonesian students can be illustrated from the results of the PISA 2015 test and evaluation [1]. The average score of achievement of Indonesian students for science is 403 which is ranked 62 out of 69 countries evaluated [2] This shows that the performance of Indonesian students' thinking is still relatively low, as well as evidence that Indonesian students are still dominant in low levels, or more in their ability to memorize in science learning [3]. One of the multiple choice tests that can assess students' understanding and level of thinking, namely the diagnotic three tier test. Researchers are interested in conducting development research entitled "Development of Knowledge Assessment Instruments Three-Tier Diagnotic Test Based on higher order thinking skills"
