Are classes and lessons for security officers in Connecticut available in Spanish?

I don't have an exhaustive list of which training facilities offer training in which languages unfortunately.

You can check the extensive school directory for classes and schools and contact the schools within your area directly. Premium school listings will also detail which languages they offer their training classes in.

All training facilities host their classes in English and many training locations offer classes in Spanish and a few offer classes in other languages.

Best course of action is: "ask" and if you don't get the answer you want, ask them if they know of a school that does, they might be able to give you a referral to another location.
