Okla. Admin. Code § 340:2-1-55
A local personnel file is set up in each office. Documentation in the file includes, but is not limited to, official communications, training records, performance evaluations, supervisory memoranda, and similar material relating to the employee. The divisions and units housed at Oklahoma Department of Human Services (DHS) State Office building may instead use the records maintained by Human Resource Management. The employee and any individual in the line of authority above the employee may review the employee's personnel file either in the local office or in the state office. Local administrators or selecting officials may review personnel files for employees who are seeking assignment within their offices. Other DHS officials may review an employee personnel file when there is an administrative need. Any other requests to review employee personnel files are handled per and are subject to the limitations of the Oklahoma Open Records Act and the Oklahoma Discovery Code. Section 840-2.11 of Title 74 of the Oklahoma Statutes prohibits public inspection or disclosure of state employees' home addresses, phone numbers, and Social Security numbers.
