This study provided a mixed-methods case-study design evaluation of the Leadership in Blended Learning (LBL) program. The LBL program uses blended approaches, including face-to-face and online, to prepare school leaders to implement blended learning initiatives in their schools. The findings suggested that LBL was largely successful in helping educators apply their learning within their profession settings. Also, it's suggested that using a blended approach can help scale high quality professional development for principals.
