How do I find out how I will need to finish out the school year? How do I properly notify the school? He has already met his "levels" to begin second grade and is in some third-grade "levels." How long does it take to get set up to homeschool and how do I do it?
Your first step is to find out what the homeschooling laws are in your state. Homeschooling is legal in all states, but requirements vary quite a bit. I would also contact a homeschooling support group near you, and speak with a homeschooling family. Often, experienced homeschooling families can guide you and help you interpret the laws. For lists of homeschooling laws by state and a support group near you try:
Once you know the legal requirements, simply notify the school that your son will not be returning, and you will be homeschooling him. This is your legal right as a parent.
At this point, my concern would not be keeping him at his grade level, but rather providing a safe, loving environment so he can regain his confidence. From your description, he is a very bright boy, and will easily catch up to his peers with a minimum amount of effort when the time is right. Please visit our homeschooling channel and read the homeschooling articles. Also, The Beginners Guide To Homeschooling by Patrick Farenga will help you get started with a minimum amount of effort. Good luck!
