Barriers to students’ academic achievement have gained importance in educational research. The primary goal of this study was to determine the level of barriers to effective family involvement in education and student achievement of the 5 selected public elementary schools. The researcher used descriptive-correlational method using a standardized and validated questionnaire. The respondents of the study were the 86 B’laan parents of 5 public elementary schools of Kiblawan in Davao, Philippines using universal sampling. Employing mean and Pearson r as statistical tools, results showed that the level of barriers to effective family involvement to education and to the level of student achievement were both moderate. Moreover, results indicated that there is a significant relationship between the barriers to effective family involvement to education and student achievement in government primary institutions. Students had the confidence on their parents’ ability to assist them in their studies. However, there is a need to train students to be academically inspired through parental involvement in school activities since some of them avoid their parents’ engagement in school programs. Likewise, parents outside the cultural mainstream such as the B’laan may feel that they are not capable of contributing to their children’s education. Thus, they are less likely to become involved in school activities.
