This study utilized a longitudinal person-centered approach to investigate how children's achievement goals combine with the goals held for them by their parents and teachers to form unique achievement goal profiles among a sample of 619 elementary school students (M_age = 9.782; 52.5% female; 79.2% first- and second-generation immigrants) from low SES ethnically diverse neighborhoods. Our results revealed four distinct profiles that proved to be identical from one school year to the next: (a) Low on all Goals, (b) High on all Goals, (c) Mastery-Oriented, and (d) Low Mastery Goals. Students' membership in these profiles was moderate to highly stable over time. Moreover, all profiles were marked by a correspondence between student, parent, and teacher goals, suggesting that elementary students may come to develop a global understanding of the various goal-related messages present in their environment. Higher perceived competence in core academic subjects was associated with membership into profiles characterized by high levels of mastery goals. The Mastery-Oriented profile fared best in terms of academic achievement and anxiety, whereas the Low Mastery Goals profile fared the worst. This Low Mastery Goals profile was unique to our study and represented the largest profile, which could be related to the socioeconomic status of our sample. Our findings provide information regarding the nature and stability of achievement goal profiles among elementary school students and offer new insights into how children interpret goal-related messages in their environment.
