Final answer:
A Licensed Professional Counselor must report any knowledge of unlicensed counseling practice to their licensing board to maintain the integrity of the profession and client safety.
Step-by-step explanation:
Yes, a Licensed Professional Counselor (LPC) is generally required to report to their licensing board knowledge of any unlicensed practice of counseling. This is to uphold the integrity of the profession and ensure that individuals receiving counseling services are protected. The practice of counseling without a license is illegal and can put clients at risk, as unlicensed practitioners may not have the necessary training or adhere to professional ethical standards.
