“…Various studies discussed the importance of enablement through leadership between health and educational sectors to achieve a negotiated and shared vision for HPS as a joint initiative [ 32 , 45 , 57 ], tailored support with evidence and planning tools [ 47 , 48 , 62 , 69 , 72 ] and flexibility that allows for development based on the local needs of schools [ 32 , 42 , 68 , 69 , 72 ] (environmental restructuring) . It was perceived that a balance between these conditions, that appreciates the need for “rigidity and flexibility” [ 51 ], would encourage ownership by schools to facilitate HP into practice and enhance sustainability [ 34 , 42 , 43 , 52 , 56 , 72 ]. Many studies also discussed the important role of a trained, effective coordinator to enable local planning groups to plan, implement and integrate HP [ 39 , 40 , 43 , 52 , 56 , 63 , 68 , 70 ].…”
