Spelling/Vocabulary

I know that we don't concentrate on spelling at the middle level as much as in elementary, but I thought I would share how my 9 year old's teacher does their spelling. At the beginning of the year, the students take a pre-test on all of the words that they need to know by the end of the year. Then the students only test on the words that they missed on the pretest each week. When they finish their words for the year, then they get to pick their spelling words. For example, my daughter is choosing Greek vocabulary words and books of the Bible. She LOVES it!

So...for those of you who use key vocabulary terms, is this something you can incorporate? I don't know how it is done...so I am just throwing it out there.
