Acronyms can get confusing! Here are a few definitions to get you started:
ZTC - Zero Textbook Cost (ZTC) refers to the cost of a course. It is used as a course designation and indicates that there is no textbook cost for the course. These courses might use library resources or other free resources that are not OER.
LTC - Low Textbook Cost (LTC) also refers to the cost of a course. To be designated as a low textbook cost course, the total price for all required text materials must be $40 or less, with the following clarifications:
- The LTC designation is based on the cost of new materials, not used books or rentals.
- The LTC designation may be based upon the cost of an e-book or a printed text.
- The cost of homework sites or software platforms is included in this total.
- The costs are based on pre-tax prices of new course materials in the bookstore or through the publisher.
- LTC courses may require supplies that are not included in the LTC total, such as calculators, test forms, clay, or safety goggles.
OER - Open Educational Resources (OER) refers to a work's license meaning they have open licenses. This means that the copyright owner retains few if any rights. You can use, reuse, adapt, and distribute however you would like so long as you follow the terms of the license.
