I've made the claim before that homeschooling is in fact cheaper than sending a kid to free public school. One of the more common responses I've received from that piece is that, sure, they can see that for a younger kid, but once kids get into high school or even middle school, that isn't the case at all. I disagree. I firmly believe that it is especially true of older children. As schools start demanding more expensive supplies and fees, homeschooling can remain as close to free as you'd like it.
And now I have proof.
This month, I've been homeschooling my oldest, a very bright almost 13 year old, who is doing entirely high school or college level work...for free.
Yes, eventually there will come a time when I won't be able to educate him for free any more, as things like chemistry require more equipment that maybe I won't be able to find for free, but community colleges do have such equipment and homeschooled high schoolers can enroll at such colleges from a young age (here it is 14 years old, I've heard), at which point they aren't strictly homeschooled kids anymore. They've begun their college education...at a much lower cost than I did.
