Subclaims¶

q2 i? Teachers who rate their principals as effective and supportive are less likely to leave their schools, and this impact is largest in high-need schools. → Darling-Hammond 2026 q2 i? Principals rated highly on setting clear expectations, support, and recognition reduced teacher attrition enough to offset the turnover differential between disadvantaged and other schools. → Darling-Hammond 2026 (2)

National survey data reported in the review: teachers who strongly disagreed their administration was supportive were "more than twice as likely to move schools or leave teaching" than those who strongly agreed. No standardized effect size is printed.

"National survey data show that teachers who strongly disagreed that their administration was supportive were more than twice as likely to move schools or leave teaching than those who strongly agreed that their administration was supportive."

A cited study reported in the review found highly rated principals reduced teacher attrition "enough to offset the turnover differential between disadvantaged schools and other schools." The report frames building leadership capacity as a high-leverage equity strategy.

"principals rated highly on “setting clear expectations, providing support and encouragement, and recognizing staff for a job well done” reduced teacher attrition “enough to offset the turnover differential between disadvantaged schools and other schools, as defined by student demographics.”"
