As Lee Corso would say " No so fast my friend "... Independent school of course are public, but they set no boundaries along their district. So student that resides in the county can enroll to an independent school for a fee. In other words. Out of district student.

Open enrollment as it is called is a local issue. Any school board my choose to permit out of district students to enroll. They also set the fee that is paid.
