Hirshman, 6-foot-4, 230 pounds, completed 59.1 percent of his passes with two touchdowns and seven interceptions last season. He has two years of eligibility remaining.
Hirschman, who earned a degree in sports communications in three years and was set to have his a graduation ceremony Thursday night, said he believes Terry Bowden is an excellent coach and he was impressed by Akron's facilities.
He surprised some by transferring despite finishing the spring as Colorado's co-starter alongside Connor Wood.
In four Colorado spring scrimmages, Hirschman was 32-of-52 passing for 433 yards, seven touchdowns and one interception with a passer rating of 178.9.
Hirschman's departure came on the heels of Colorado quarterback Jordan Webb tearing an anterior cruciate ligament.
