Course Descriptions


How to Read Catalog Course Descriptions

Texas Tech offers nearly 5,000 courses as part of its curriculum. These courses are listed alphabetically by subject prefix within each college and departmental section of this catalog. The courses appear in numerical order, moving from beginning freshman or developmental level courses to graduate, research, and professional courses.

Not all courses listed in this catalog are offered every year. An online class schedule published before each registration period indicates courses that will be available during the upcoming term or semester and when each class will meet. The class schedule can be found at (www.depts.ttu.edu/officialpublications/class_schedule/index.php). The university reserves the right to cancel any scheduled course or withdraw any program from the list of offerings when the best interests of the institution require such action.

Courses are designated by a subject prefix and number along with a descriptive title. Learn more  about interpreting the course descriptions found throughout the catalog.
