The present study examined the stability and change of students' motivational profiles from Grade 7 (Time 1) to Grade 9 (Time 2), using task values and self-concepts of ability in mathematics, Finnish language, and arts as indicator variables. The study also examined the effects of students' (Grade 7: N=231; Grade 9: N=237) motivational profiles and of their parents' educational expectations at Grade 7 on their short- and long-term educational plans at Grade 9, controlling for gender and academic achievement. The latent profile analysis identified four motivational profiles: (1) low motivation group; (2) high motivation group; (3) math-motivated group; (4) practical group, which were highly stable from Grade 7 to Grade 9. The results showed that, compared students in the practical group at Grade 7, the students' in the high motivation group and in the math-motivated group were significantly less likely to aim for a degree from a vocational school than a degree from an academic track (short term), or a university (long term). Furthermore, mothers' and fathers' high expectations for students' short- and long-term plans at Grade 7 contributed positively to high educational expectations among adolescents at Grade 9. •Latent profile analysis identified four motivational profiles.•Profiles were stable from Grade 7 to Grade 9.•Students' motivational profile membership predicted their educational plans.•Mothers' and fathers' expectations predicted students' educational plans.
