This study, conducted by the Office of Shared Accountability (OSA) in Maryland's Montgomery County Public Schools (MCPS), aims to describe the characteristics of the teaching staff in MCPS, as well as to examine differences across levels and types of schools. The analysis is mainly descriptive and intends ultimately to inform policies and practices that will support successful teacher staffing in the district. The Employee and Retiree Service Center (ERSC) and the Office of Human Resources and Development (OHRD) provided MCPS teacher data, and other reliable sources were consulted to compare district findings with state and national trends. The following questions guided the study: (1) What are the characteristics (demographic, education, experience) of current teachers and newly-hired teachers in MCPS? (2) Do the characteristics of current and newly-hired teachers differ among MCPS schools with different levels of poverty, complexity, and school climate? (3) What were the MCPS teaching position vacancies at the start of the school year and did they vary among schools with different characteristics? What does the candidate pool look like? and (4) What is the rate of teacher attrition in MCPS and does it differ by teacher and school characteristics? The methodology and findings of each research question are detailed in this report.
