ALOA CPL study guide
ALOA CPL · Work through your exam, one topic at a time.
The ALOA Certified Professional Locksmith (CPL) is a professional credential in the locksmith and physical security field, offered in the orbit of ALOA Security Professionals Association, Inc., a Dallas-based association whose stated mission is "furthering the industry through education, leadership and promoting professionalism and ethics for security professionals worldwide." ALOA organizes its education and member activity around four divisions - AIL (Institutional), IAAL (Automotive), IAIL (Investigation) and SAVTA (Safes and Vaults) - and these four areas define the knowledge base a CPL candidate is expected to command. The credential suits working locksmiths who already handle commercial hardware, vehicle locks, forensic or investigative lock work, and safe or vault servicing, and who want a single certification demonstrating breadth across all four rather than depth in one. The ALOA CPL study guide has 4 sections and about 1,068 words.
