The top academic officer of Jefferson County Public Schools has submitted a letter of resignation that criticizes leadership of the state's largest district.
Media report that Dewey Hensley said in his letter that working conditions have deteriorated, leading to "marginalized voices, eroded credibility" and more time devoted to managing perceptions than to developing quality schools.
Hensley submitted the letter on Thursday and said his last day would be Friday.
Superintendent Donna Hargens said in a statement that she was "saddened" by Hensley's decision. He called him "an unwavering champion for the success of all students."
As the chief academic officer, Hensley helped the district's effort to improve persistently low-achieving schools and implement new testing mandated by the state.
