In this study, the authors were interested to understand how lesson study (LS) protocols were adapted to suit local school conditions and contexts and the kinds of problems and constraints the schools faced in the implementation process. The Sixty-four schools responded to three survey questionnaires. The findings reveal that 56 schools implemented LS. Twenty-nine schools indicated that they would definitely continue implementing LS. The results show that in 22 schools LS was initiated by school leaders such as principals and vice-principals.
