A pilot program designed to keep Oklahoma State University faculty members in the classroom longer is being extended. The OSU/A&M Board of Regents approved an extension to the faculty phased retirement pilot program Friday at the board's meeting at Langston University. The board approved the pilot program at its February 2011 meeting. The plan allows OSU faculty members to retire from the university with full benefits and return to work half-time after a 60-day waiting period.
