This study used a nationally representative sample of African American and Caribbean Black adolescent females to examine the relation between perceived pubertal timing relative to peers and discriminatory experiences. Participants included the 607 girls who participated in the National Survey of American Life‐Adolescent (NSAL‐A), and ranged in age from 13 to 17. Most African American girls perceived their development as on‐time relative to their same‐aged peers; whereas the majority of Caribbean Black girls perceived their development as earlier than their same‐aged peers. The results indicated that girls who perceived that their pubertal development was earlier than their same‐aged peers reported more general and racial discrimination experiences.
