NORFOLK, Va. (AP) — A fourth-grade teacher in Norfolk who staged a mock auction of black and mixed-race students as part of a Civil War history lesson is on administrative leave.

Norfolk Public Schools Chief Operations Officer Michael Spencer tells The Virginian-Pilot an investigation of Sewells Point Elementary teacher Jessica Boyle will be completed no later than next week.

Spencer says a recommendation on any personnel action could go before the school board as early as May 18.

Division spokeswoman Elizabeth Thiel Mather has said the teacher separated black and mixed-race students from their white classmates and auctioned them.

Principal Mary B. Wrushen apologized to parents in a letter earlier this month. She said the activity wasn’t supported by the school or division.
