Multivariate regression on NTPS/TFS data using the leadership effectiveness and supports index, reported in the report's summary of its multivariate results. The report states predicted turnover was "reduced by half—from 18.7% to 9.0%" between low and high leadership groups.
"The predicted probability of turnover was reduced by half—from 18.7% to 9.0%—when comparing teachers who reported low versus high levels of leadership effectiveness and supports."
