The LET’S CARE Safe Education model aims to create a comprehensive framework that addresses various levels of analysis through attachment theory, ecological perspective, and an inclusive education approach. This model is designed to address educational disparities and promote safe learning environments for all students.

Central to LET’S CARE is the collaborative process of co-creation, which involves stakeholders throughout the development of the model. By integrating findings from secondary desk research and qualitative primary research, the project identified four nested research pillars: Safe Learner, Safe Teaching, Safe School, and Safe Education. Each pillar consists of specific dimensions essential for understanding and enhancing children's well-being and academic performance.

The model was co-created through a stepwise process involving internal and external validation to evaluate the chosen dimensions and variables, followed by the assessment of available measures for their applicability, reliability, and validity. This process was conducted by seven working groups composed of stakeholders and experts, with four groups involved in the first phase and three in the second phase.

Internal validation involved feedback from four project internal working groups of stakeholders and experts, ensuring the relevance and coherence of the proposed dimensions and variables. Content validation was performed through a two-round Delphi design with 57 experts divided into three groups, refining the model based on clarity, adequacy, and relevance criteria.

Cross-cultural validation carried out with the project’s working groups ensured the questionnaires' relevance and appropriateness across different linguistic and cultural contexts. This process involved a Committee-Based Translation Framework and cognitive interviewing with children, leading to adjustments that improved the reliability and validity of the measures.

The results of this process are manifested in the collaborative development of a theoretical and operational model, which represents a pioneering approach to addressing the multifaceted and complex phenomenon of Safe Education.
