D.C. Mayor Vincent C. Gray, making a widely anticipated decision official, lifted the "interim" from Kaya Henderson's title Wednesday, naming her succeed to Michelle A. Rhee as D.C. schools chancellor.
Henderson, 40, the daughter of a high school principal and Rhee's former top deputy, is the only candidate Gray ever seriously considered for the post. She has also received an important series of public and private endorsements from Education Secretary Arne Duncan and the influential philanthropic community that underwrites many public education initiatives in the city.
