I made a post awhile back about Scholastic, wondering if I could have a teacher's account since I'm homeschooling. Well, I called today and got it all setup, switched from my parent account to a teacher account. They officially recognize homeschoolers now (not sure if they did in the past) so it's not as hard to do, but you do have to talk to someone over the phone and answer a few simple questions.
Here is the number you can call to setup the account. If you have an active parent account, tell them you want to switch.
"I researched your user name (xxxxxxxxx), and we are happy to establish a Book Club account for you if you are a teacher at a public, private, parochial, or charter school or if you are home schooling your child (kindergarten and above)."
