Okla. Admin. Code § 610:1-11-17
Employee training services may be acquired without competitive bidding if necessary to accommodate the needs of the agency. The requesting unit must provide written justification for an exemption from the competitive bidding requirements. The requesting unit should consider (1) employee work schedules, (2) potential for interruptions in service, (3) cost of interruptions in service, and (4) the number of employees already trained for the particular purpose. All acquisitions under this section must be approved by the Chancellor or the Chancellor's designee. The Chancellor will require a periodic review of all costs associated with employee training services, including any associated travel expenses, to ensure that the costs are reasonable.
