This study explores how parental attributes including parental education, occupation and the type of parental interaction affect different types of LoC of secondary school students. A total of 520 students were selected as participants of the study. Brown Locus of Control Scale (BLOCS) was the instrument of the study. ANOVA and t-test were used to explore the differences in LoC of students with different parental attributes. Results showed that internality was significantly more in students who moderately share their feelings with mothers. Other externality was significantly more in students whose fathers were businessmen than in students whose fathers were employees or laborers, and in students who completely or moderately share their feelings with their mothers than those who do not share their feelings with their mothers. External social LoC of students with less mother education (elementary and graduation) was significantly higher than the students with higher (postgraduation) mother education.
