The secondary school transition may be important for identity change. We investigated identity change and subgroups therein, and whether personal and environmental factors explain subgroup membership. Data was used from four timepoints across the last year of primary and first year of secondary school from 241 adolescents (M age = 11.6, range 10.5–12.8). Identity change was generally in the direction of higher pre-transition commitment and lower post-transition commitment and exploration, with most change as well as differences therein manifesting post-transition. Neuroticism and best friend support did not predict group membership; parental support predicted more adaptive change. These findings suggest educational identity change around the transition and especially during its runup is relatively normative, with strong expectations of how adolescents should change
