Billing and Licensing

For nearly 12 years from 2005-2017, the CATME system was maintained through funding from the U.S. National Science Foundation. In order to support a growing user base, we have implemented an annual license fee for using CATME. Currently, CATME operates as a Recharge Center (not-for-profit) within the College of Engineering at Purdue University which means that we charge only enough to cover our costs.

Your annual CATME license fee is determined by your unique student count, and is based around a tiered pricing schedule. CATME's licensing period begins on July 1st annually and ends June 30th of the next year. CATME does not charge any licensing fee to pre-collegiate education.

A CATME license provides unlimited CATME use in the current license year for instructors and students. Instructor and student CATME data will also be retained indefinitely at the instructor's discretion for grading or research access at no charge. The license fee is fixed at the beginning of the license year, and adjustments to the unique student count license fee will be made upon renewal, one year in arrears. This way, there will not be any obstacles to adding students to surveys.

The total license fee is based on all the unique students under instructors in the previous academic year. Future estimates of students for the upcoming year can be used instead of historical data for first time CATME users and for special requests.

Who pays to use CATME?

Currently, institutions, colleges/schools, departments, or instructors are charged for CATME use, depending on the license type.

Types of Licenses

CATME offers various types of licenses to suit the needs of the Institutions we work with. Each license varies on the scope of instructors it covers.


This license is available for any instructor who is interested in using CATME for creating teams or using peer feedback tools.


This license accounts for all instructors within a given department at an institution. CATME will charge for each unique student only once within the department. If multiple departments have departmental licenses at the same institution, each department's student list will be unique to a department.


This license accounts for all instructors and students at an institution. This covers all departments and schools/colleges. CATME will charge for each unique student only once within the institution.

Unless there is already an existing license for your department, school/college, or institution, CATME will assign an individual or department license to your account by default. If your account is already covered under a license, CATME will automatically assign a license to you. Different license options must be requested at All licenses allow unlimited CATME use for students and instructors.

Paying for License

An official invoice from Purdue University will be sent to you containing the dollar amount of the license fee and the information needed to complete payment. If you have used CATME in the past, you will receive your invoice annually after July 1st. If you are a new user to CATME and your institution/department does not have a license yet, you will receive your invoice shortly following the first survey creation. Invoices can be paid via check, wire transfer, debit card, or credit card.

If you wish to be notified about the charge before the invoice is sent, CATME can produce a quote. To request a quote for your CATME license, please email
