ADAPTATION OF ASSESSMENT LITERACY INVENTORY INTO TURKISH

In Turkey, teacher competencies in assessment are mainly determined through questionnaires and interviews asking teachers' perceptions, which generally disregard the standards for competencies in assessment and performance indicators described by the Ministry of National Education. Thus, there is a need for an instrument which is designed according to the Ministry's Assessment Standards. In order to meet this need, this study aims to adapt Assessment Literacy Inventory developed in 2005 by Mertler and Campbell into Turkish and evaluate its psychometric properties. The sample consisted of 260 pre-service teachers in total. According to the item analysis results, overall instrument reliability (KR20) was 0,859, mean item difficulty level was 0,644, mean item discrimination level was 0,486. The psychometric qualities of the inventory strongly support its use as an acceptable measure of teachers' assessment literacy and, thereby, teachers' professional development needs related to assessment can be revealed. This will pave the way for effective and efficient professional development initiatives to improve teachers' competencies of classroom assessment.
