In addition, trustees appointed Chris Holleran, Bill Morones, Christine Richardson, Marie Schirmer and Julianna Sikes as school support administrators.

The board also approved an accountability plan and $219.6 million budget that includes more professional development, funding for high school sports and fifth-grade instrumental music, improved parent outreach and campus supervision, and extra support for low-income students, English learners and foster youths. Trustees also agreed to spend $240,000 to jointly fund school resource officers at high schools in Concord, with the city paying an equal amount.
