DC schools chief Kaya Henderson to step down

Kaya Henderson is stepping down after more than five years as chancellor of the District of Columbia's public schools.

Henderson succeeded the polarizing Michelle Rhee and continued her predecessor's education-reform policies. But she had a more low-key style and better relationships with parents, teachers and elected officials.

Henderson has fired hundreds of teachers under a system that evaluates them in part based on their students' performance on standardized tests. The teachers who fare best under the evaluation system receive bonus pay.

Under Henderson, city students have shown improvement on standardized tests known as the "Nation's Report Card," but the achievement gap between white and black students has remained persistently high and has increased by some measures.

Henderson announced Wednesday that she will resign effective Oct. 1.
