LINCOLN, Neb. (AP) — The executive director of the Nebraska School Activities Association has resigned a month after the association’s board of directors voted not to extend her contact.

Rhonda Blanford-Green, a former All-America track athlete at Nebraska, took over as executive director in July 2012. She’d spent 16 years as an administrator with the Colorado High School Athletic Association.

She said Monday that her decision to resign “is in the best interests of the association.”

In May the board decided not to lengthen her contract beyond June 2016. Board chairman Brian Maher, who voted to extend the contract, cited personnel privacy in declining to say why the board’s majority voted against the extension. A year ago the board voted unanimously to extend Blanford-Green’s contract for a year.
