The study focused on the relationship between parental treatment methods and school bullying among the eighth grade students in North Batinah Governorate in Oman. In doing so two instruments were used: a scale of parental treatments prepared by Farouk Jibril (1989) and a scale of school bullying prepared by Muawiya Abu Ghazal (2009). The study followed the descriptive/correlational method. The sample for the study consisted of 400 students, distributed equally between boys and girls. The participants were randomly selected. The data was analyzed using the statistical software program SPSS (Statistical Package for Social Sciences). The most significant results of the study were as following: 1. The average scores of the study sample on the boys bullying scale were all within the low range, while the girls were at a very low range. 2. There was a positive correlation between the methods of parental treatment and the school bullying 3. There were importance differences at the level of significance (a< 0.05) due to the gender variable in favor of boys in the methods of parental treatment and school bullying. 4. There were no importance differences in the methods of parental treatment due to the educational and economic level of the family. In the light of the findings of this study, some recommendations are given.
