Investigating the Distribution of Teacher Quality by Race/Ethnicity and Socioeconomic Status of Students by School in One Large School District

The purpose of this study was to examine the relationship between teacher quality variables, student demographic variables, and student performance in order to determine the influence teacher quality variables have on student performance in one large school district. The population for this study included 69 schools during the 2007-2008 school year within one large suburban school district. Included in this study were 47 elementary schools, 14 middle schools, and 8 high schools. In this three-phased study, descriptive correlations were examined, t-tests were conducted comparing each of the variable sets, and partial correlations were conducted in order to determine the strength of associations between teacher quality variables and student performance variables. Findings from this study showed several strong and significant associations. When comparing the highest and lowest quartile of schools based on average years of teaching experience, percentage of within-district transfers, and total teacher mobility, there was a significant difference seen in both the percentage of economically disadvantaged (ED) students and percentage of African American and Hispanic students combined. Further analysis showed a significant difference between the top and bottom quartiles of percentage of ED students and percentage of African American and Hispanic students combined and their performance in both math and reading. Findings showed that teaching experience was negatively associated with student performance in reading and math, however, there was a smaller association in math. Controlling for within-district teacher transfers had a small to medium association between African American and Hispanic students combined and commended performance or meeting standard in math and reading. When controlling for percentages of total teacher mobility (leavers + movers) from campuses, there was a strong negative, partial correlation between percentage of ED students and performance in math (commended only) and reading. Implications for practitioners include the need to improve school leadership, improve working conditions, provide more and better professional support, create incentives to work in challenging schools, improve preparation for work in challenging schools, streamline hiring placement policies, create a coherent set of policies to close the staffing gap, and provide greater funding targeted to student needs
