Teacher readiness is the willingness of a teacher to implement a planned program successfully. Readiness is crucial in ensuring a program can be implemented at the individual or organizational level. The readiness of science teachers to implement Classroom-Based Assessment (CBA) determines the direction and success of primary school assessments in Malaysia. This pilot study aims to create and evaluate the Inventory of Science Teachers' Readiness in Implementing Classroom-based Assessment (ISTRI-CBA). There have been many studies on CBA. However, there are limitations in measuring the readiness of science teachers to implement CBA. Therefore, it is necessary to have an inventory that is strong conceptually and psychometrically. This challenge was addressed by developing the ISTRI-CBA, which has five measurement dimensions: knowledge about CBA, skills of CBA, resource support, attitudes, and professional values. The development of ISTRI-CBA requires validity and reliability for it to be used. This study aims to (1) test the quality characteristics of the ISTRI-CBA items and (2) determine the reliability of the ISTRI-CBA obtained using the Rasch Model measurement. The research involves the administration of a survey questionnaire to 44 science teachers in a district in Malaysia. The findings show that the ISTRI-CBA comprising 168 items, has good psychometric characteristics and meets the measurement criteria of the Rasch measurement model. The item quality and reliability also prove that the whole dimension is suitable. The findings show that the ISTRI-CBA can measure science teachers' readiness to implement CBA.
