Ohio School Employees Retirement System, Columbus, will launch a search for a general investment consultant before the end of the month, said spokesman Tim Barbour in an e-mail.
The $12.8 billion pension fund will issue an RFP due to the expiration of current consultant Summit Strategies Group's five-year contract on June 30, 2016.
The pension fund's policy requires the bidding of vendor services every five years. Summit is invited to rebid.
The pension fund hopes to select finalists by the end of the year and make a decision by May.
The RFP will be posted on the pension fund's website.
