Case studies form the third phase of the validation study for the Myanmar Teacher Competency Standards Framework (TCSF) in advance of its implementation in 2020. As the purpose of the case studies is to ensure that the TCSF is culturally and contextually appropriate, this paper outlines the results of data analysis on the Case Study component. This report focuses on responding to four key research questions: Which standards, minimum requirements and indicators were easiest and hardest to demonstrate? How is effective teaching demonstrated by the selected teachers in Myanmar? How does the evidence of effective teaching differ in different contexts? and how did participants and researchers engage with the study as a professional learning exercise?
