California Code, Public Contract Code - PCC § 20919.31

(a) Prepare for each individual job order developed under a job order contract an independent school district estimate.  The estimate will be prepared prior to the receipt of the contractor's offer to perform work and will be compared to the contractor's proposed price to determine the reasonableness of that price before issuance of any job order.  The basis for any adjustments to the school district estimate is to be documented.  In the event that the contractor's proposal for a given job order is found to be unreasonable, not cost effective, or undesirable, the school district is under no obligation to issue the job order to the job order contractor, and may instead utilize any other available procurement procedures.

(b) The school district shall not issue a job order until the job order has been reviewed and approved by the appropriate level of management.

(c) Once a job order has been issued, all documents pertaining to preparation and approval of the job order, including the independent school district estimate, shall be available for public review.
