Social contagion has been documented across various domains. However, this phenomenon has not been explored in relation to formative assessment in schools. This study examines the social contagion of school teachers’ formative assessment practices and self-efficacy. A sample of 296 teachers from 12 Hong Kong primary and secondary schools participated in this study. All participants completed the same questionnaire twice, one year apart. The longitudinal results showed that formative assessment practices and self-efficacy were socially contagious. When teachers had colleagues who engaged in formative assessment practices and had high self-efficacy, they were more likely to engage in formative assessment and become more efficacious themselves. Also, school-level formative assessment self-efficacy predicted individual-level formative assessment practices demonstrating the importance of collective efficacy. The findings can inform the provision of school support and the design of teacher professional development programmes for promoting formative assessment in schools. Copyright © 2023 Informa UK Limited, trading as Taylor & Francis Group.

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.
