This case study examined teacher professional learning in the context of the Abu Dhabi New School Model educational reform initiative. Data were collected through semi-structured interviews that were conducted with teachers and school leaders. The study's findings reveal a serious disconnect between formal policy, practice, and implementation as teachers lacked agency and many constraints prevented them from engaging in further professional learning opportunities. These constraints and challenges included a lack of organizational support, time, and choice in the school's professional development programs. Recommendations and implications for policy and practice were drawn based on the findings.
