Here's some info on our Teacher Only paid membership plans.
Teacher Only membership plan
The Teacher Only membership plan does not include paid student accounts, and only extends membership privileges to your teacher account.
Teacher Only plan members can invite up to 40 users (a combination of teachers and/or students) to your classes. Students and teachers that are added to your class will not be given paid memberships, and will either need an activated free trial account, or have a personal membership in order to join.
Teacher Only plan members have access to all Challenges and Courses, and can assign them to their class. Students in your class that have a paid membership will be able to access all Challenges and Courses you assign. Students in your class that have free trial accounts will only be able to access Challenges and Courses you assign that are also available to free trial members (free trial members have a limited selection of Challenges and Courses to choose from).
Please note: with a 'Teacher Only' membership plan, teachers and students you add to your class are not given paid memberships. Users can independently purchase a membership for their own account, or you can upgrade to a Classroom and School Plan which can include up to 200 paid teacher and student memberships here
