Board of Education President Richard Barrera, Trustee Shelia Jackson and Superintendent Bill Kowba lead the ceremony, which was attended by about 100 of this year's retirees.
"I thank you for all your hard work in helping each generation take its place," said Barrera. "This is a team effort, whether you are teaching, providing support at a school or central facility, or here at the Ed Center."
Jackson said each would be missed but invited the retirees to return as volunteers.
"We still need your experience and skill, so I hope you will continue to help our kids," she said.
In his remarks, Kowba lauded the retirees for their legacy.
"We commend you for your service and the countless hours you have dedicated to making a difference in the lives of thousands of San Diego students," he said. "We also extend our appreciation to your family and friends for their support and, sometimes, sacrifices.
"You have our best wishes for good health, happiness and all the rewards you so richly deserve."
The ceremony, an annual tradition, was organized by the Human Resources and Communications department. It featured the Monroe Clark Middle School Advanced Band and catering by the Food Services Department. Sponsors of the event included California Coast and Mission Federal credit unions.
