This study aimed to identify profiles of achievement goal orientations and transitions between these profiles among adolescents from different socioeconomic backgrounds before and during the Covid-19 pandemic. A sample of 1268 adolescents (51.7% females; Mage = 14.87; SDage = 0.39) participated in four waves of data collection: One took place pre-pandemic (at the start of 9th grade) and three took place during the Covid-19 pandemic. Latent transition analyses revealed four profiles of achievement goal orientations at each study wave: moderately motivated, success-oriented, mastery-oriented, and unmotivated. Most adolescents remained in the same profile or transitioned to a similar one across subsequent study waves. However, some more substantive, mostly unfavourable patterns of transitions between the profiles were also observed, especially among highly motivated adolescents. The latter patterns coincided with pandemic-related online learning periods. Results also showed a large motivational disadvantage among students from socioeconomically disadvantaged backgrounds, which was particularly pronounced before the pandemic, but remained salient throughout the study
