(b) Any school district requiring prospective bidders to complete and submit questionnaires and financial statements, as described in subdivision (a), shall adopt and apply a uniform system of rating bidders on the basis of the completed questionnaires and financial statements, in order to determine the size of the contracts upon which each bidder shall be deemed qualified to bid.

(c) Each prospective bidder on any contract described under Section 20111 shall be furnished by the school district letting the contract with a standardized proposal form that, when completed and executed, shall be submitted as his or her bid.  Bids not presented on the forms so furnished shall be disregarded.

(d) A proposal form required pursuant to subdivision (c) shall not be accepted from any person or other entity who is required to submit a completed questionnaire and financial statement for prequalification pursuant to subdivision (a), but has not done so at least five days prior to the date fixed for the public opening of sealed bids or has not been prequalified, pursuant to subdivision (b), for at least one day prior to that date.

(e) Notwithstanding subdivision (d), any school district may establish a process for prequalifying prospective bidders pursuant to this section on a quarterly basis and may authorize that prequalification to be considered valid for up to one calendar year following the date of initial prequalification.
