LXD Research ESSA Level 2 Teacher Retention Study

Measuring the Impact of e2L Coaching Methodology on Teacher Retention

Report Sections:

Study Description

engage2learn (e2L) provides a personalized coaching system that builds capacity and engagement in public schools. Learning Experience Design (LXD) Research, a third-party independent evaluator, was hired to analyze data collected from the Arlington Independent School District (ISD) during the 2017-2021 school years. The goal of this study was to measure how participation in coaching conducted by e2L coaches and e2L-trained district coaches predicted teacher retention each year.

This well-designed, correlational study suggests that e2L’s methodology for instructional coaching interventions meets the standard for ESSA Level 2 Moderate Evidence by having a statistically significant impact on teacher retention results.

Program Overview & Key Findings

e2L partnered with the district to provide coaching for teachers, instructional lead teachers, assistant principals, instructional coaches, and office staff. Teachers were coached on the e2L Best Practices and worked with their e2L coach or e2L-trained district coach to design their own path toward standards mastery within the district-selected competencies, earning competency badges as they demonstrated evidence of practice.
Teacher retention data indicated whether a teacher returned to their position at the beginning of the next school year. The following results provide evidence that educators who were coached using the e2L coaching methodology and earned competency badges were significantly more likely to continue in their role than educators who did not receive coaching nor earn badges.
