You can't. In New York State you must attend the required courses in person and pass a finger print check. NY does not have any online education options at this time.

You can take an express class which will allow you to pass in a few weekends if you go full time, But you will still have to do the 45 hours in person. NYU has a great express program as does Hunter University. There are others of course.

A list of requirements and approved schools can be found here:
