One of the benefits to being a homeschooler is the lack of focus on tests and assessments. Our state law requires homeschool students to take the state assessment in 3rd, 5th, 8th, and (I think) 11th grades. You are supposed to submit the official results back to the district (thought the acceptable standards are shockingly low, like 15%ile).

However in practice a) tons of people don't bother and no one seems to care b) even if you do they may refuse to accept the results because of bureaucratic paperwork BS (happened to us) and c) you don't have to spend any time preparing if you don't want to.

DDs learning center organizes testing for the state assessments as well as general achievement testing. For the latter, you can sign up for any grade level that makes sense. This means above level testing at the parent's discretion.
