(740 ILCS 110/3) (from Ch. 91 1/2, par. 803)
    Sec. 3. (a) All records and communications shall be confidential and shall not be disclosed except as provided in this Act. Unless otherwise expressly provided for in this Act, records and communications made or created in the course of providing mental health or developmental disabilities services shall be protected from disclosure regardless of whether the records and communications are made or created in the course of a therapeutic relationship.
    As used in this subsection, "confidential" has the same meaning as in paragraph (3) of subsection (b) of Section 5 of the Court Record and Document Accessibility Act.
    (b) A therapist is not required to but may, to the extent he determines it necessary and appropriate, keep personal notes regarding a recipient. Such personal notes are the work product and personal property of the therapist and shall not be subject to discovery in any judicial, administrative or legislative proceeding or any proceeding preliminary thereto.
    (c) Psychological test material whose disclosure would compromise the objectivity or fairness of the testing process may not be disclosed to anyone including the subject of the test and is not subject to disclosure in any administrative, judicial or legislative proceeding. However, any recipient who has been the subject of the psychological test shall have the right to have all records relating to that test disclosed to any psychologist designated by the recipient. Requests for such disclosure shall be in writing and shall comply with the requirements of subsection (b) of Section 5 of this Act.
