Data were gathered through questionnaires using simple random sampling. The analysis included descriptive statistics for demographic details and statistical tests like Chi-square, one-way ANOVA, and t-tests to explore relationships between variables. The results showed a strong positive impact of teacher-parent collaboration on students' grades, behavior, motivation, and attitudes toward learning.
