Course Number Explanation
Each course is designated by a four-digit number. The first digit denotes the level of the course. Course numbers beginning with the number zero typically indicate a non-credit course, courses beginning with number one (1) are freshman-level courses, while those beginning with the number two (2) are normally considered sophomore-level courses. The second digit indicates the value of the course in semester hours in all courses except vocational nursing. The third and fourth digits are used to identify the sequence or designation within a department. Beginning fall, 1992, Navarro College joined with other two- and four-year colleges in Texas to adopt a common course numbering system. The purpose of this system is to assist students who are transferring between participating institutions.
