As far as I know, at least in my state, there aren't any training requirements. Though the MSF (Motorcycle Safety Foundation) course is big here, it is not required. The only requirement is that you are of age and able to pass the test that is given at the DMV (Department of Motor Vehicles) before being licensed. From what I hear, the motorcycle license test isn't all too difficult if you have an inkling of what you are doing. Tests and exceptions differ from state to state, though. If you take a certified course like the MSF, you may be able to bypass the DMV test depending on your state of residence.
