This qualitative multiple-case study examined the implementation of an experiential learning component of an academic curriculum in six high schools in Turkey. Structures and supports that influenced programme implementation were examined using an implementation framework adapted from Durlak and Dupre. The study describes how the experiential learning programme is implemented. Findings indicate four areas that need ongoing attention: (1) supports for programme coordinators, (2) teacher training, (3) integration with academics and (4) school cultures that better support experiential learning.
