State Superintendent of Public Instruction Libby Burmaster will not seek a third term.

Burmaster's decision was reported Tuesday by the Milwaukee Journal Sentinel.

Tony Evers, Burmaster's deputy since she took office in 2001, announced he will run in the spring to replace her.

The 54-year-old Burmaster had not indicated that she intended to step down before her surprise announcement.

She told the newspaper that she wants new challenges, but she doesn't know yet what they are.

Her current term as the state's highest ranking education official for kindergarten through 12th grade runs through June.

The 56-year-old Evers ran against Burmaster in 2001, lost in the primary and then became her deputy.
