There is no difference in the TeacherMade application. The only difference is how much it costs. If you have 20 Teachers but only 500 students at your site, you’ll want to purchase the Unlimited Site License. 20 Teachers x $59 = $1,180 BUT… 500 students at $1.33 per student = $665. It’s a little confusing when you first look at our plans, but once you do the math, you’ll understand that we’re trying to bring you the best instructional technology at the lowest possible prices. We’re on your side!
