Abstract
This study aims to determine the ability of the learning outcomes even chemistry assessment instrument used in schools, the feasibility level of the HOTS assessment instrument based on content validity, the results of item analysis on the HOTS assessment instrument using Rasch model analysis. The method used is RnD which consists of some stages such as analyze, design, and development. Based on the results of the needs analysis, it was found that the chemistry learning outcome assessment instrument used in schools had not been able to measure students^ HOTS abilities. Thus, a learning outcome assessment instrumen was developed to measure HOTS. The results of the content validity test by lecturers and teachers obtained in the valid category. There are assumptions test in Rasch model, namely the assumption of unidimensionality with Principal Component Analysis (PCA) and local independence that have been met with the model. Then on the results of item analysis with Rasch, 33 out of 40 questions were categorized as good to be used as a tool to measure students^ HOTS. This study produces a product in the form of a valid chemistry learning outcome instrument and can be used to measure students^ HOTS abilities and can be used online.
