• Design: A longitudinal 2-group quasi-experimental design involving 4687 primary students from 165 classes of 27 primary schools .
• Experimental group: teachers received intervention comprising professional development on feedback and SDL during the first year of the study; Delayed-control group: intervention only in the second year.
• Data on feedback, SDL, and mathematics achievement were collected at 6-month intervals.

• The project presents the first longitudinal quasi-experimental study in HK in naturalistic primary classrooms settings on feedback, SDL and mathematics achievement.
• The model developed and the study findings will inform teaching and learning, particularly about the effect of assessment feedback on primary students

• Measurement scales on mathematics achievement, feedback, and SDL for primary students developed and validated.
• Primary students and their teachers were found to have very different expectations on and attitudes toward feedback.
• After controlling for prior mathematics achievement, students’ attitudes toward feedback had significant effect on later achievement. The effect was mediated through attitudes toward attaining personal best.
