I'm avoiding answering HS'ing Q's right now out of grief... But had to chime in here:
Add 2 words together
"Texas & Homeschool"
& you have a chorus of angels singing from on high amidst the backdrop of millions of envious homeschoolers. Or, to quote:
The Governor of Texas says: "In Texas, we view home schooling as something to be respected and protected - respected for the energy and commitment of parents; protected from the interference of government. Texas does not index or monitor home school programs."
What's involved?
Nada.
You simply inform the school you'll be homeschooling (but are not even legally required to do so).
That's it.
Finis.
Done.
If you're looking at reentry later... Its fairly easy. Although, Id personally homeschool via dual enrollment & get 2 years of collehe under my son's belt & get to apply to colleges later under the AWESOME homeschool track (unfairly advantageous to homeschoolers, honestly, since the portfolio system allows for MAJOR bragging / "why you want me" AND so many schools are recruiting homeschoolers the way that sports schools recruit athletes. I'm not joking about GRIEVING giving up homeschooling. My son's future prospects dimmed dramatically when he had to re-enter public school.)
Here's a link to Ann Zeiss's collection of Texas homeschool links

And... As always... The Secular Homeschoolers Group (as well assny others) on yahoo groups, is an outstanding resource.
I'm sorry for your son's troubles, but envious of his opportunities!
All my best,
R.
