AU - علي، غادة عبد الرحيم AB - The objective of the current research is to define the nature of the structural model of the relationships between bullying school, music engagement, and academic performance among second grade pupils in middle school. The final sample consisted of (462) students of whom (241) were males and (221) were girls. The research used the following statistical analyzes: The confirmatory factor analysis (CFA), the T- test, the correlation coefficient, the multiple regression analysis, and the path analysis using the SPSS.V.(25) program. Program Liseral.v.8.8, where the results showed the following. There were statistically significant differences at the level of (0.01) between the mean scores of males and females in school bullying and the sub-components, physical, verbal, psychological, subversive and cyber bullying in favor of males. There is a negative correlated relationship and a statistically significant function at level (0.01), between: bullying school, music engagement, and academic performance. There is a positive correlated relationship and a statistically significant function at level (0.01), between: the engagement with music and academic performance. It is possible to predict the engagement with music with school bullying and its various components. Academic performance can be predicted by school bullying and its various components. Independent variables music engagement and academic performance were able to explain about (82.6%) of variance in the scores of the dependent variable (school bullying), indicating the high level of practical significance of the proposed model.
