It means what it says, instead of kids having to go to the designated public school in their district, they can chose to go to a for-profit school of their choice anywhere. Instead of taxpayers financing your kid’s education, you do. Instead of your kid learning to protest, learning faux US and world history, leaning that Democrat leaders know best, they learn real history and to be responsible, think for themselves, to acquire life long habit of reading books, and so forth.
Ah okay. However, people with the means pretty much do this anyway.
