Easiest way to get an adult driver license and/or maybe driving school?

Hey everyone! So my daughter is 20 and doesn't drive. Never been behind the wheel before. I plan on starting to take her out to start practicing this weekend, but I'm wondering how the easiest way for her to get a license is. Should I find a drivers Ed school to send her to? Should I teach her myself and she can just go take the tests and get her license? I'm am old and back in the 90s I went to drivers Ed, did behind the wheel instruction and only had to take the written test to get my license at 16 and I know things have changed alot lol. If driving school is the best way anyone have any school suggestions? We're in the sugarland area. Thank you all so much!!
