Ill. Admin. Code tit. 44, § 1300.4535
b) Pricing Approval
While notice and competition is not required prior to contracting with a certified work center for persons with significant disabilities, prices must be reasonable. Whether a price is reasonable will be determined based upon current market prices, historical prices, prices received by other State agencies for similar goods or services, the policy of the Code to promote procurements from certified work centers, and other such relevant factors.
