My curriculum does a lot of quizzes and tests and I've really struggled with this. I have the option to not assign them, but I've felt like we should be doing them for high school. Yet, I feel like they aren't very useful and kind of a waste of time as I care more about my children understanding the subject matter. The discussion in the comments so far has been very helpful!

Don't think there's a "PERFECT" curriculum for various subjects! It's still true in high school that the perfect curriculum is the one that works well for you and your child. There are many really good offerings...check out Cathy Duffy's book or website for a listing of great curriculums and find the one that's best for your family : )

Also, Lee's point about "Don’t think you have to change everything to homeschool high school" helped me resist the temptation to think I HAD to stop reading history to my kids when they entered 9th grade. I beefed up a 7th and 8th grade history curriculum with Teaching Company DVDs and read the books to my kiddos (Lee's suggestion) and we created wonderful memories through those times (& my son was able to do great on a CLEP test of that subject)! Thanks a million Lee!

Never, Never sacrifice your relationship with your child over schoolwork.

Don't be afraid to learn something new alongside your child, and don't be afraid to "fail" that class yourself while your child easily gets an "A!" Case in point - Latin. We both love it. I'd flunk it if I were in a conventional school, my student would definitely get an "A." But as long as I have my cheat sheets, I can at least follow along, and my student is learning a lot because we consult with each other about new concepts and my student learns a lot from correcting my papers. Seriously.

Suzanne, I mean the daily curriculum you use does not need to include tons of tests:

Don't be terrified of subjects your children want to study that you can't teach. The necessary resources are out there! Find them, help your children access them, and provide accountability as well as encouragement (kudos!) while they take some responsibility for their OWN dreams and future. You don't have to teach everything--facilitate and manage instead!

Number 6 is very thought-provoking!

Regarding #4; do you mean SAT type tests or course specific tests? My son took Algebra I in 7th and I had him take the CBE while it was fresh. He'll take the Geometry CBE this coming summer. Do you think I should have waited until later to test him?

Thanks Lee! I thought that's what you had in mind but wanted to clarify.

Don't be afraid to include their non-book activities on transcripts. Example - working part-time at vet's office = credit in "Intro to Veterinary Science". or spending countless hours writing code for online gaming = "Computer Programming"

Don't ever say, "I'll homeschool until they get to high school, then I'll send them to school." Why undo all that you've accomplished in their lives, when what you are doing is what is best for them and has worked all their lives?

Stephanie,
Some people think they need to change their homeschool just because their kids are entering 9th grade. They may think they MUST use tests, MUST use classical education, or MUST use textbooks. My advice is do what works. Even in high school, LOL!
Blessings,
Lee

Actually could you clarify #3? What do you mean by that?

Yep. If you have overachieving kids, don't let them over-commit.
