Museum leadership in a statement Wednesday said former Massachusetts Attorney General Scott Harshbarger of Casner & Edwards LLC will lead the review.
The museum conducted its own investigation, which led to two patrons being banned for alleged disparaging remarks during the May 16 visit.
But the museum says "we came to the decision that an investigation by an external party could provide greater objectivity and clarity."
Principal Arturo Forrest of the Helen Y. Davis Leadership Academy in Boston said museum security followed his students while leaving white students alone.
