About the Department

This department supervises the following degree programs and certificates:

A total of 120 hours is required for a B.S. degree. Students seeking a master’s or doctoral degree in the department should consult the chairperson about their programs before enrolling for any courses.

The department is the academic home to the Fiber and Biopolymer Research Institute (FBRI), which is internationally known for its expertise in cotton. FBRI focuses on research, education, and technology transfer pertinent to fibers, textiles, and biological based polymers. While it is an integral part of the Department of Plant and Soil Science in the College of Agricultural Sciences & Natural Resources, FBRI also collaborates with departments in the Colleges of Engineering, Arts & Sciences, and Human Sciences, offering opportunities to students for special projects and thesis research.

Communication Literacy Requirement. Beginning with the Fall 2017 term, Texas Tech University’s Writing Intensive requirement for certain courses will move to a Communication Literacy requirement. Students who are following catalogs published prior to the 2017-2018 academic year should consult with their academic advisors for information on how any outstanding Writing Intensive requirements will be completed. Students attending Texas Tech for the first time beginning with the Fall 2017 term or later will complete the Communication Literacy requirement in their program(s) of study.

Texas Tech University’s transition from the Writing Intensive requirement to the Communication Literacy requirement signals the university’s awareness that in addition to the fundamental role that writing plays in enabling students to explore, develop, focus, and organize a message, other types of communication must also be taught as appropriate for a student’s discipline. Throughout each program of study, then, students must be given ample opportunity to develop their skills in forms of communication central to that program.

All students following the 2017-2018 catalog should consult catalog information specific to their program(s) of study for more information about their Communication Literacy requirement.
