Lynne Mooney Teta, the embattled headmaster of Boston Latin School, has resigned, according to reports.

Teta faced criticism earlier this year for her handling of alleged incidents of racism at the exam school. U.S. Attorney Carmen Ortiz announced in March her office would investigate civil rights violations at the school.

Teta announced Tuesday in a letter to parents she will leave her position at the end of the school year.

Boston Public Schools Superintendent Tommy Chang supported Teta amid calls for her resignation from the African-American community.
