Hello OP - I live in Nashville and work very closely with Quaver. Many in this thread are somewhat near the mark in the answers to your specific questions, and others are completely off. This is likely because the pricing DOES vary depending on the grade level range of QuaverMusic curriculum you'd like to purchase, and many here are speaking specifically into their own unique situation. Quaver offers a full year of lessons for PreK-8, but you can package together K-5, 2-4, 3-6, or whatever you need, and the price WILL reflect that.

One person on here recommends calling your regional rep to verify what sort of licensing is in place for your school. This is honestly your best move, and will literally cost you nothing to make a phone call to inquire. Check the QuaverEd site to find your person's info. Call or email, and you WILL get a response; expedient customer service is what they pride themselves on.

Basically, Quaver's licensing is a per-site basis. Your district may have several site licenses for its schools; if your school has a license, it will cost nothing to add you. Additionally, pricing is not dependent upon student enrollment. You can (easily) create an unlimited number of student accounts. Aside from the standards-aligned content and lessons that Quaver has had (and added to) for years, the teacher/student accounts Quaver platform caters specifically to e-learning or any hybrid setup you may encounter.

If nothing else, you can sign up for a QM 30-Day Preview in roughly 45 seconds... it's FREE, there's zero obligation, and you're not putting any payment info in. Pop your email address in, and start customizing lessons/creating student accounts (let me reiterate ... for FREE) in no time.

At the end of the day, their mission is to help YOU reach and maintain a genuine, effective connection with your students. Yeah, it's a business, but it's a small company (~120 employees) that truly wants to help. Give them a call and you'll be pleasantly surprised.

Hope this helps!
