InterProjects Mexico pre–post questionnaire dataset (students, teachers, families)

This dataset contains anonymized pre–post questionnaire responses from secondary students, teachers, and family members who participated in the InterProjects model in one public and one private school in Mexico. The questionnaires assessed perceptions of educational equity, inclusion, intersocial and intercultural relationships, and educational continuity using 5-point Likert-scale items (1 = strongly disagree to 5 = strongly agree). The file includes item-level data for 200 students, 50 teachers, and 50 family members who completed both waves, along with basic sociodemographic and school-type variables. The dataset was used to construct the contingency tables, chi-square tests, and Cramér’s V statistics reported in the article “Project Equity: Inter-School Programs for Intersocial and Intercultural Competency Development.” All direct identifiers have been removed, and school and participant information has been aggregated to protect confidentiality.
