I just learned about another essay contest for students ages 13-18. I added it to my writing contest page, but thought I’d post about it also, so that no one misses it. It is Stossel in the Classroom’s What’s Great About America essay contest and is open to kids aged 13-18. Homeschoolers are specifically mentioned as being welcome to participate! There are multiple cash prizes.
BTW, I am not promoting any political views here.
