Chapter 39.34.040 RCW, the Interlocal Cooperation Act, provides the authority for Washington State agencies such as OSPI 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, OSPI has elected to publish a list of Interlocal, Interagency, and Intergovernmental Agreements on this web page. The list below contains Agreements by Fiscal Year, starting with 2019.  To view a list of Interlocal Agreements between 2006 and 2019, please contact contracts@k12.wa.us.
