What does your child want to do after HS graduation? Work, more schooling? Does the IEP prepare your child for this? For example, if your child gets extra time for tests and wants to go to college, this is an accommodation they can get on SAT/ACT as well as on tests in college. I'm not sure with a homeschooler, who applies to the testing companies for any accommodations. In a public school, the guidance dept tends to do this.
