A convergent parallel design was used in the study.

The research included a sample size of 1023, which included 769 students from 49 public high schools, 6 Quality Assurance and Standards officers (QASOs), 49 principals, the same number of Deputy Principals, and 150 teachers who are disciplinary committee members. The results of the study showed a strong correlation between students' academic achievement and their level of gambling. Furthermore, the degree of student gambling activity has a big impact on attendance at school. The study makes recommendations by looking into the reasons why students miss school.
