This research aims to determine the extent of implementation of the school disciplinary rules and regulations among junior high school (JHS) students and to identify the factors that affect the students’ behaviors which may influence their compliance. The researcher used a mixed-method evaluative research design. The school personnel participated in the study were the following: administrators; guidance counselors, prefects of discipline, and teachers. Based on the assessment of the school personnel, it shows that the most implemented was “substance use” and the least implemented among the areas of disciplinary rules and regulations were ‘uniform guidelines’ and ‘use of facilities.’ Moreover, significant differences were determined in the assessment of extent of implementation of school personnel in selected JHS in Caloocan City. As a mixed study, it is the full intention of the researcher to garner the deep-seated responses of the participants as to how extensively they implement the school guidelines. The research tried to codify the most common theme reflected by each participant’s answer to the openended questions that were deliberately asked after answering the set of quantitative items. The particular intention of the proposed action plan is to continue the improvement of the implementation of disciplinary rules and regulations.
