This paper presents the qualitative findings from a recent doctoral study that examined the leadership practices of 17 middle school administrators from three school districts in the Canadian province of Alberta (Rheaume, 2018). The data gathered through six focus group interviews are framed within the three dimensions of Brown et al.'s (2002) Developmentally Responsive Middle Level Leadership (DRMLL) model, illustrating ways that middle school leaders are responsive to the development of: (a) young adolescent students by understanding their developmental characteristics and establishing engaging, equitable learning environments that empower them to thrive; (b) faculty by establishing a shared vision and a collaborative culture focused on continuous improvement; and (c) the middle school itself by implementing the organizational structures of the middle school concept that promote meaningful relationships and learner success. Although the findings of this study aligned with the DRMLL model, they also led to suggestions for expanding it to better reflect current leadership practices and the newly revised middle school concept (Bishop & Harrison, 2021). Even so, DRMLL has stood the test of time for nearly two decades and continues to serve as an excellent foundation for middle level leadership.
