Correlations with Middle School MBST Value-added Math gains were significantly correlated with: A) School size = -.45 B) Core teacher turnover = -.41 Reading gains were significantly correlated with: A) Percent African American = -.48 B) Core teacher turnover = -.42 C) Percent students of color = -.42 D) Use of leveled reading books = .31 E) Teacher years in the district = .39

Math gains were significantly correlated with:

A) School size = -.45

B) Core teacher turnover = -.41

Reading gains were significantly correlated with:

A) Percent African American = -.48

B) Core teacher turnover = -.42

C) Percent students of color = -.42

D) Use of leveled reading books = .31

E) Teacher years in the district = .39

Correlation Caveats Small sample of data from the middle school team rankings of variables Most data other than teacher turnover and enrollment are “soft indicators” Correlation does not imply causation. That is, we don’t know that turnover causes low achievement; it may be that low achievement causes turnover; or that both are caused by another highly correlated factor (e.g. poor leadership)

Definition of Core Teacher Turnover Percentage (The total number of core teachers during the past three years minus the total number of core teacher positions) divided by total number of core teacher positions For example: 9 total teachers in 3 years = (9-3)/3 = 200%

(The total number of core teachers during the past three years minus the total number of core teacher positions) divided by

total number of core teacher positions

For example:

9 total teachers in 3 years = (9-3)/3 = 200%

Simple example 5 of 28 schools had core staff turnover exceeding 200%: ANDERSEN OPEN 222.00 CITYVIEW 258.00 GREEN CTR PARK 317.00 LINCOLN 330.00 JORDAN PARK SOEL 443.00 These schools had an average MBST score 10 pts lower than the other 23 schools with less than 200% turnover
