This study is descriptive-exploratory research that aims to determine the impact of the preschool program on teacher respondents’ perceptions in the Indanan South District of Sulu. Various statistical tests, such as weighted mean, standard deviation, t-test, one-way ANOVA, and Pearson’s r test, were used to analyze the data. The following findings were obtained from the study: The majority of the one hundred teacher respondents are married, between the ages of 26 and 30, female, possess a bachelor’s degree, and have worked for less than five years. The method of thinking subcategories pertaining to the influence of preschool programs on a child’s primary school performance received an “agree” rating with a weighted mean score of 3.71 and a standard deviation of 0.79174. The teacher respondents in the Indanan South District, on the other hand, rated the behavior-related subcategory as “moderately agree,” with a weighted mean score of 2.90 and a standard deviation of 0.85952. Regarding the perceived impact of the preschool program, age, gender, duration of service, civil status, and educational attainment did not correlate significantly. This finding indicates that, notwithstanding their demographic characteristics, the teacher participants held comparable perspectives regarding the influence of the preschool program in the Indanan South District. Moreover, a robust interdependence was observed among the subcategories pertaining to the magnitude of the influence of preschool programs in the Indanan South District, as evidenced by the high correlations between them.
