Academic Credit

All courses offered for academic credit through UC Davis Extension are identified by an "X" designation that precedes the course number (e.g., X199). Below is the course letter and number key to UC Davis Extension courses.

  • X1-99 Lower division courses
  • X100-199 Upper division courses
  • X200-299 Graduate level courses
  • X300-399 Professional level Teacher Education
  • X400-499 Professional level courses
  • XD1-399 Campus-equivalent courses

The letter "A" following the course number indicates the course is the first in a series, the letter "B" indicates it is the second in a series, and so forth.
