You can call Experior at 888-277-3500 for information on the CNA exam and testing requirements. The state of Florida has all of the licensing an testing outsourced to this company.
I recently ordered a CNA info package from them, and you can certainly take the exam without having taken a CNA prep course.
According to the package, there are two testing centers in Orlando:
- Center for Professional Training
- Life Care Center of America
Give Experior a call. The package will have all the info you are looking for (even a very description of the clinical skills test).
