This article aims to study the relationship between teachers' judgment and pupils' self-perceptions controlling for the big-fish-little-pond effect (BFLPE). Three studies were conducted among third-grade pupils. Study 1 (n = 585) focused on pupils' perceptions of their scholastic competence. Teachers' judgment and BFLPE were found to have an independent relation with pupils' self-perceived scholastic competence. Study 2 (n = 660) replicated the same results of study 1. Study 3 (n = 683) extended the analysis to other domains of self-perception identified by Harter ("Child development," 53, 87-97, 1982). The results showed that the relation with the BFLPE was significant only for pupils' self-perceived scholastic competence. They also showed that the teachers' judgment was related to two other domains of self-perception (behavioral conduct and peer acceptance) but was not directly related to pupils' global self-worth.
