Institutional Pricing
All of your students and faculty can benefit from our institutional memberships. Your students can learn the fundamentals of critical thinking by working through activities designed by our world class leaders in critical thinking. The purchaser of the institutional key is designated the administrator, and all others fall under the rules set by the administrator. Institutional membership accounts differ from regular accounts in that they can have either full or reduced access to certain portions of the site, which will be set by the administrator of your account. Our libraries and academy sections are ideal for students. Additionally, the administrator can at any point add or delete accounts within your institutional membership. Institutional membership rates are based on student FTE's.
