Accounts Payable


Purchasing allows us to have the necessary materials, supplies and equipment to successfully perform Dieringer’s primary responsibility—educating our students! We are responsible for initiating and maintaining effective and professional relationships with suppliers, and we serve as the channel through which all requests regarding products and prices are handled. 

With the exception of textbooks, the manner in which we procure furniture, supplies, equipment, building improvements or repairs, or other work or purchases for the district must be in compliance with RCW 28A.335.190.


Thank you for your interest in doing business with Dieringer School District. If bid opportunities are available, they will be listed here. Bids typically consist of supplies and/or equipment expected to cost $75,000.00 or more. From time to time, the district may also seek bids for goods or services of any value if deemed appropriate. 

Cooperative Agreements

Chapter 39.34.040 RCW, the Interlocal Cooperation Act, provides the authority for Washington State agencies such as Dieringer School District to contract with other governmental entities. The law was revised in the 2006 legislative session and requires Interlocal Agreements either be filed with county recording offices, or published at a location electronically accessible by the public.

To satisfy this requirement, Dieringer School District has elected to publish a list of Interlocal, Interagency, and Intergovernmental Agreements on this web page. The list below contains the agreements


Purchasing in the Dieringer School District follows Federal and State guidelines.
