Texas Common Course Numbering System (TCCNS)

The Texas Common Course Numbering System is designed to aid students in the transfer of freshman and sophomore academic credit courses identified by institutions that are members of the TCCNS.

The common course number has a standardized four-letter prefix followed by a four-digit number. The four-letter prefix identifies the subject area. For example, ENGL represents English courses, while COSC represents computer science courses. The four-digit number identifies specific courses within the subject area. TCCNS numbers appear following TWU course numbers when applicable in this catalog. 

Each digit in the four-digit sequence gives additional information about the course. The first digit identifies the course as either freshman level (1) or sophomore level (2). The second digit identifies the number of semester credit hours students earn upon completing the course. Most often this digit will be a 1, 2, 3, or 4. The final two digits serve to establish the sequence in which courses are generally taken. Thus, French I - FREN 1311 is taken before French II - FREN 1312.
