Florida is one of the states where an individual may challenge the nursing assistant exam without completing a training program first so the answer is YES unless you have already failed part of the certification exam three times. A state-approved training program is not required prior to testing in Florida but it is strongly recommended. If you plan on taking the exam without going through a training program then please be aware that you need to be 18 years of age OR have a high school diploma or its equivalent. There are certain advantages and disadvantages either way but it is definitely possible in Florida.
