Successful implementation of formative assessment in classrooms relies on teachers’ formative assessment literacy, which is typically supported by professional development programs. This study reports on the impact of a professional development program on a group of in-service primary teachers in Hong Kong. The authors investigated the effectiveness of the program in developing teachers’ formative assessment literacy and how far the program assisted them in addressing the challenges they faced when implementing formative assessment in classrooms. With a mixed-method design, quantitative data were collected with a pre- and post-program survey (N = 27); qualitative data were collected with open-ended survey questions and a focus group with six participating teachers. The results provide evidence of the program’s success in developing teachers’ formative assessment literacy and equipping them with the necessary skills to address the challenges in implementation. The features of professional learning communities embedded in the program contributed to the positive impact of the program. Copyright © 2023 Teacher Development.

This study investigates the relationship between students’ attitudes towards formative assessment and summative assessment and aims to enrich the understanding of formative and summative assessment from the students’ perspective. A total of 3,019 Hong Kong primary school students responded to a newly developed instrument. Overall, students reported positive instrumental yet negative affective attitudes towards formative and summative assessment. Girls had less negative affective attitudes towards formative assessment, but more positive instrumental attitudes towards formative and summative assessment than boys. Grade 4 students consistently scored higher than Grade 5 and Grade 6 students in assessment attitudes. The gender and grade differences were statistically significant, but had small effect size. Moreover, it was found that students’ affective and instrumental attitudes to formative assessment positively predicted students’ affective and instrumental attitudes to summative assessment.
