First and foremost, if you spend any amount of vacation time wondering when school will start again, don't even consider Home Schooling.
Home Schooling is an idividual decision. If you feel you can handle your child and the manifestation of his disabilities on a full time basis, without the "break" offered by the school day that's great. However you will need to have and stick to a schedule every single day, no exceptions at all.
Additionally, even if the child is home schooled the local school district should be involved, you should still have an IEP, and if you want, some classes you can't realistically provide can still be taken in school or through the IU.
There are some practical noneducational things you should seriously consider about your child's development before you make a decision...
1. Social skills: most ADHD children lack them, how will you deal with the need for him to learn to socialize with peers? and the lifelong learning of socialization?
2. Authority: most ADHD children lack the ability to acknowledge and respect the authority of adults and professionals, does your child have the proper respect for you to be educated by you? How will you teach your child a respect for others in authority to carry him into adulthood and the workplace?
3. There are a host of counseling issues that are actually addressed in behavior contracts and Special Education Classroom settings. Are you prepared for counseling aspects of Home Schooling a Special Needs Student?
It takes a greal deal of patience, understanding and redirection to do what you are considering. Make sure you make time for yourself so that you don't burn out.
Good luck, A.
