Find a program that offers training for a Class D license and complete initial training. The fastest way to get a Class D license is to complete 24 hours of initial training, and some classes are offered in three eight-hour sessions. Although a total of 40 hours are required under Florida law, it's also possible to submit an application after 24 hours. Tuition for the course ranges from about $50 to $100.
Submit your application. The application can be submitted to your nearest branch of the Department of Agriculture and Consumer Services or to the main office in Tallahassee. You must include proof of training, a passport-size photo, a fingerprint card, a $45 licensing fee and a $42 fingerprint processing fee.
Complete additional training. After completing 24 hours of initial training, you must complete the additional 16 required hours (usually in a two-day program) within 180 days of the date your application is submitted. As with the initial training, these hours must come from a state-licensed security training facility. In most cases, you can complete your training with the same company that provided your initial training. Additional tuition fees may apply.
