The present study aimed to identify the principles of effective home-school interaction and their corresponding strategies in cultivating a positive attitude toward a faith-based lifestyle among junior high school students. This research is qualitative in nature and was conducted using thematic analysis. Data were collected through comprehensive library research, observational notes, and semi-structured in-depth interviews. Participants were identified using non-random, purposive, and theoretical snowball sampling among educational experts. Through data analysis, three primary themes emerged as the core principles of effective home-school interaction for fostering a faith-based lifestyle: the principle of trust, the principle of mutual understanding, and the principle of synergy. Furthermore, sub-themes associated with each of these primary themes were identified and presented as corresponding practical strategies. The identification of these principles and strategies provides a framework for policymakers to formulate appropriate regulations, for curriculum planners to adopt effective methodologies, and for practitioners to ensure the systematic implementation of these educational goals.
