What does the Texas parent-taught driver education program require, and how does it relate to professional instructor-taught courses?

1. Parents cannot teach driver education in Texas
2. Parents may teach using a TDLR-approved curriculum; the parent-taught course covers the same content as instructor-taught courses but is administered by the parent/guardian
3. Parent-taught courses are shorter than instructor-taught courses
4. Parent-taught courses do not include in-car instruction
