Amends existing law to establish additional provisions regarding supplemental contracts.

School districts and charter schools pay some certificated employees to work extra days, (called extended days), beyond the standard teaching contract year. Employees such as school counselors, speech language pathologists, school psychologists, PTE instructors, IT personnel, school nurses or others may work anywhere from 1 to 60 days beyond the end of the standard teaching contract year. School districts and charter schools are required to issue contracts to all certificated employees using a state-approved contract which does not allow districts to differentiate between the standard teaching contract and extended days. The inclusion of extended days on a standard teaching contract creates a property right for these certificated employees, and removes any flexibility in amending the designation of extended days by the local board of trustees, which may create an unintended financial burden on a district's budget. This legislation would allow school districts and charter schools to issue separate contracts for those extended days.
