Feasibility, acceptability, and appropriability of a national whole-school program for reducing school violence and improving school coexistence.

Introduction: The increase in school violence following the COVID-19 pandemic underscores the need for schools to adopt a multilevel whole-school approach. This study examines a national program designed by the Chilean Ministry of Education, in collaboration with universities, as part of the Ministry's Educational Reactivation Plan, aimed at improving school climate management across Chile.

Methods: The "Learning to Live Together Program" (LLT) was implemented across all 16 regions of Chile, focusing on establishing school climate networks, providing direct intensive university technical assistance, and enhancing professional development and training.
