TDCJ Courses of Instruction

Explanation of Course Numbers

Trinity Valley Community College participates in the Texas Common Course Numbering System, designed to assist students who are transferring between higher education institutions. Each course is assigned an alphabetic prefix that specifies the department offering the course and a four-digit number.

  • The first of four digits identify the academic level of the course. Freshman, or first-year, courses are designated by a 1; whereas, sophomore, or second-year, courses are designated by a 2.
  • The second digit specifies the number of semester credit hours awarded for completion of the course. The third and fourth digits establish course sequences within a program area.

Each TVCC course also has three numbers in parentheses following the course title. The first number indicates the number of credit hours for the course. The second number indicates the number of lecture hours the course meets each week. The third number indicates the number of lab hours the course meets each week. For example, (3-3-2) indicates a three-semester credit hour course that meets for three lecture hours and two laboratory hours each week. Developmental studies and developmental co-requisite courses are an exception to this designation. They carry no semester-hour credit and cannot be used for graduation purposes.
