For those of you with homeschoolers grade 8 and up, how do you determine mastery? Do you quiz? Test? Up until this year, Ive never given grades. Our goal was more so, understanding. I didnt require mastery of anything other than grammar and math. Now we are getting to the point where study skills, mastery and all of that good stuff is important and Im trying to help set a precedent as we move forward into high school years.
