The four licenses that CATME offers are listed below. You will receive a pending license on your CATME account until a license is purchased or applied to your account. Unless there is an existing license for your department, school/college, or institution, a CATME license will need to be purchased. All licenses allow for unlimited CATME use. The minimum fee for all licenses is $100. The determination of unique student counts varies across the four license types.

  1. Individual license–available for any instructor who is interested in using CATME for creating teams or using peer feedback tools.
  2. Departmental license–covers all instructors within a given department at an institution. Each unique student across the department is only counted once. If multiple departments have departmental licenses at the same institution, each student list will only be unique within the departments.
  3. Institutional license–covers all instructors within an entire institution. All students will only be counted once across the institution.
