Who shall keep a roster of all duly licensed and registered Chemical Engineers?

• A. PICHE
• B. PRC
• C. Board of Chemical Engineering
• D. Senators and Congressmen

Answer: (C)

The official roster of who is legally allowed to practice Chemical Engineering is maintained by the regulatory body that oversees the profession. The Board of Chemical Engineering is the specific authority entrusted with licensure, registration, and discipline for chemical engineers, so it keeps the official list of all duly licensed and registered practitioners. This roster is used to verify credentials and ensure compliance with professional standards. A professional association like PICHE may maintain its own member directory, but that is not the official licensure record. The broader Professional Regulation Commission oversees many professions, but the formal roster for a particular field rests with its dedicated board. Senators and Congressmen do not manage professional licensure rosters.
