Purchasing - RFPs/Bids

Our office is responsible for the purchasing of goods and services in keeping with the laws of the State of Michigan and the purchasing policies of Kent ISD.  Our goal is to spend funds in the best way possible in support of improving the educational experience at Kent ISD.

Kent ISD uses Sigma VSS for any purchases above the current bid threshold of $24,459 as established by the Michigan Department of Education (MDE). Sections 623a, 1267, and 1274 of the Revised School Code establish a base above which competitive bids must be obtained and provide for an increase in the base that corresponds with increases in the Consumer Price Index.

Visit Sigma VSS for more information on any open Request For Proposals (RFPs).
