In 2011, the New York City Department of Education (NYCDOE) and the City Council's Middle School Taskforce launched the Middle School Quality Initiative (MSQI) as an instructional intervention for improving literacy levels in the lowest performing middle schools in New York City. The initiative grew rapidly and now serves over 100 schools and 53,000 students. When designing last year's evaluation, MSQI leadership and the Research and Policy Support Group (RPSG) agreed to focus on uniformly collecting implementation fidelity data. The 2014-2015 fidelity survey provides a snapshot of MSQI implementation in SY 2014-15, describing pillar activities across all 87 schools. This brief report highlights the key findings of the evaluation and concludes with recommendations.
