Abstract

This research aimed at developing a test instrument, the Problem-solving Skills Test (PSST) for Year Four students. The researcher has carried out content validity procedures on the PSST instrument. The content validity of the test involved six content validation experts. There were ten items for the test instrument. The items on the test have been evaluated quantitatively using the Content Validity Index (CVI) to determine whether they should be retained or discarded. According to the findings, the item content validity index, I-CVI, came in at a value of 1.00 for all items. This resulted in the scale content validity index, for both S-CVI/Ave and S-CVI/UA, equal to 1.00. Therefore, the Problem-solving Skills Test (PSST) has attained a very high degree of content validity and may be administered in actual research to determine students’ problem-solving skills. Keywords: Content Validity, Content Validity Index (CVI), Problem-solving Skills, Mathematics Education, Validity of Instrument
