Which department must be contacted when a professional is licensed by the State of Illinois?

The Illinois Department of Professional Regulation is the correct authority to contact when dealing with professionals who are licensed in the state. This department oversees the licensing and regulation of various professions, ensuring that practitioners meet the necessary standards of competence and ethics. It maintains the integrity of the license holders by enforcing state laws related to professional conduct and practice standards.

When professionals seek guidance on their licensing requirements or need to address issues related to their practice, this department serves as a primary resource. Its role extends to issuing licenses, renewing them, and investigating complaints related to professional misconduct. The focus is specifically on the various licensed professions, which include healthcare practitioners, engineers, and many others.

The other choices do not serve this specific function in relation to professional licensing. For instance, the Illinois Department of Human Services focuses on providing social services and welfare programs, while the Illinois Department of Social Services, which is less commonly used, would generally not pertain to professional licensure. The Illinois State Licensing Board is not a standalone entity but rather part of the broader regulatory framework overseen by the Department of Professional Regulation. Therefore, pointing to the correct agency is crucial for professionals needing support or information about their licenses.
