I could only find limited information on the preschool schedule at First Baptist Church Of Mt. Washington. It looks like classes are held on Sundays and Wednesdays and it seems as though the sessions are often under two hours, though I'm not completely sure.
The best way to learn about scheduling and potty training requirements is to call the church at (502) 538-3633. You can also ask questions on its contact form.
If First Baptist doesn't have what you need, take a look at this list of other schools near Mount Washington, Kentucky. Best of luck and feel free to ask another question any time!
