How do I check that an Illinois therapist is licensed?

What is the difference between a counselor, a social worker and a psychologist?

Each holds a different Illinois license, and the state's lookup shows which one a person holds. Social workers are trained in clinical social work, counselors in counseling, family therapists in couples and family therapy, and psychologists hold a doctorate in psychology. Illinois has a licensed professional counselor license and a separate licensed clinical professional counselor license, and each profile names the one the person holds.

An ESA letter in Illinois comes from a professional who has a therapeutic relationship with you.

Illinois runs no ESA registry. Its Assistance Animal Integrity Act asks for written documentation from someone who knows your disability, and it leaves out anyone who issues a letter without a meaningful assessment. A licensed therapist who is treating you fits that.
