Adolescents are synonymous with the era of self-identity confusion. The effect of self-identity disorder among adolescents can be described through misconduct on school discipline. Various efforts have been made to help adolescence to achieve a positive self-identity. The situation became more challenging when adolescents known as generation Y are easily allured by the current trend. Considering this, the study was conducted to identify the profile of self-identity among adolescents of generation Y. This study was conducted in 22 secondary schools around Johor involving a sample of 807 students. Data were collected through questionnaires EOMEIS-2, which adapted and modified. Descriptive analysis showed that adolescents give a high-level perception of the identity achievement (mean=3.84) and identity moratorium (mean=3.78), and moderate level to identity foreclosure (mean=3.32) and diffusion (mean=3.43). Cluster analysis showed that a total of 276 adolescents comprise identity foreclosure, identity diffusion followed 220 students, 187 students of identity achievement and 124 students of identity moratorium. MANOVA analysis showed that adolescent identity differs significantly by gender and age. The study's findings have implications as additional information to the various parties, particularly parents and teachers as a guide in guiding adolescents to achieve positive self-identity.
