Students' acceptance and use of feedback to improve their writing may be influenced by their attitudes toward receiving such feedback. In the present study, we investigated the trajectories of students' attitudes toward receiving feedback on their writing from teachers and peers in Grades 3-7. Data were collected from 1,071 students in the fall of three consecutive academic years using a cohort-sequential design. Results indicate that students have a generally positive attitude toward receiving writing feedback by both peers and teachers at all grades. However, results of parallel process latent growth modeling suggest that these attitudes decline annually between third and seventh grade. Further, both trajectories seem to shift between fifth and sixth grade, suggesting different processes between Grades 3-5 and Grades 5-7. Finally, female students tended to like receiving feedback from teachers and peers more than their male peers.
