Ill. Admin. Code tit. 44 § 8.8020
Documents relating to responsibility determinations shall be maintained by CDB in a separate file and shall remain confidential as records pertaining to occupational registration, except that they shall be subject to complete disclosure to the vendor or design-build entity to which they relate and to units of federal, State or local government, including but not limited to, law enforcement agencies. Nothing in this Section shall be construed to mean that the name of any person or organization filing a complaint or providing information shall be disclosed when the complaint or information is used as the basis for further inquiry into the facts alleged. CDB or the CPO may release to anyone the vendor's prequalification status with CDB. Notwithstanding the foregoing, neither the Performance Evaluations nor the vendor's written responses to them shall be made available to any other person or vendor, except as authorized by Section 7(1)(b)(iii) of the Freedom of Information Act.
