Parents carry bouquets, and students wear suits and dresses at the Clark College School of Nursing’s pinning ceremony at Gaiser Hall on the Clark College Campus in Vancouver.The pinning ceremony is a favorite event for nursing school professors Lisa Aepfelbacher and Mary Ellen Pierce.

It’s expected that by 2022, more than 34,200 new educators will be needed.“It’s an issue across the state and the nation,” said Clark College President Bob Knight.A nationwide problem at the local levelAt Clark College, faculty and administrators have grappled with how to attack the issue, which has been exacerbated by recent staff departures.
