Taking Courses with Non-Matriculated Status

How to take classes without enrolling in a degree or certificate program.

Choosing a Non-Matriculated Status Type

If you wish to take classes without enrolling in a degree program or certificate, you may do this by first obtaining a non-matriculated student status. This policy also applies to auditors.

Non-matriculated (NM) student status

  • You should enroll as non-matriculated student (NM) unless you plan to apply the credits you earn toward a UW graduate degree in the future. Most people will fall into this category. You should obtain this student status if:
    • You want to take courses for personal or professional development (e.g., BIOST 511517).
    • You need to fulfill prerequisites or strengthen your background prior to applying to our Biostatistics graduate program.
  • NM students may take any undergraduate or graduate level course.
  • Obtaining NM student status is a relatively simple process. Students may register up through the first two weeks of the quarter.
  • NM students pay less tuition and fees than other students.

Graduate non-matriculated (GNM) student status

  • You should enroll as a graduate non-matriculated (GNM) student if you intend to apply to our Biostatistics graduate program at a later date, and wish to apply up to 12 credits of coursework to the possible future degree. Note,
    • The GNM application process is distinct from the regular graduate program application process, and receiving GNM status does not influence decisions about admission into the graduate program.
    • If you need to strengthen your background prior to formally applying to the Biostatistics graduate program, you are highly encouraged to strengthen your advanced math background via NM status instead. Taking Biostatistics courses rarely overrides weaknesses in an applicant's math background. In addition, a strong math background is essential to do well in our core Biostatistics courses. Be sure to review all admissions requirements for the graduate program.
    • If you would like to take a Biostatistics course that applies towards a degree in a different department (e.g., Epidemiology), you should apply for GNM status with that department instead.
  • GNM students are restricted to courses that are core courses in our MSMPH, or PhD programs. GNM students typically take either BIOST 517 or STAT 512 (Autumn) and BIOST 518 or STAT 513 (Winter), as these are the first-year applied and theory courses taken by our PhD and MS Thesis students. Those interested in the MS Capstone may also take GNM credits in BIOST 517, 518, and other pathway courses.
  • GNM status is more difficult to obtain than NM status and requires an application process. Application deadlines are September 1 for Autumn quarter; December 1 for Winter quarter; March 1 for Spring quarter; and May 15 for Summer quarter.
  • GNM students pay more tuition and fees than NM students.


  • See tuition rates for most NM and GNM students at the Non-Degree Enrollment website.
  • Tuition rates for tuition-exempt employees (both NM and GNM) are available at the Student Fiscal Services website. If you exceed 6 credits, you will be charged for the difference in tuition rates. Please contact Student Fiscal Services if you have questions pertaining to tuition.

How to Register

UW faculty, staff and WA state employees

  1. UW faculty/staff and WA state employees who are eligible for tuition exemption should carefully review the WA State Tuition Exemption Program website for details on eligibility, obtaining student status and tuition exemption, course registration, deadlines, and fees. If you have any questions, please contact the Registration Office at 206-543-8580 or regoff@uw.edu.
  2. Obtain either NM status through the steps in the WA State Tuition Exemption Program website (NOT the steps immediately below), or GNM status through the steps on this page below.
  3. Register using the steps outlined in the WA State Tuition Exemption Program website (via MyUW, NOT through the Non-Degree Enrollment office).

Non-matriculated (NM)

  1. Review registration procedures, important dates, and other information at the Non-Degree Enrollment website. For questions pertaining to obtaining NM status, please contact Non-Degree Registration Services.
  2. For most large, introductory courses such as BIOST 511 and 517, students do not need to request permission from the instructor; the department will sign the Registration Approval Form on behalf of both the instructor and the department. For other courses, you must obtain permission from the instructor. Note that some courses are strictly restricted to Biostatistics/Statistics students.
  3. Send the Registration Approval Form to our department at bcurric@uw.edu for signatures. Please do not include your social security number on the form.

Graduate non-matriculated (GNM)

  1. Review general admission requirements and registration procedures at the Graduate School GNM website.
  2.  If applying during the months of December through August, email bioadmit@uw.edu to request access to the online GNM application. Please state which degree program (MS Thesis, MS Capstone, MPH, PhD) you intend to apply to in the future.
  3. Apply online through the Graduate School Application website.
Hard deadlines for entry each quarter are as follows:
  • Autumn quarter: September 1
  • Winter quarter: December 1
  • Spring quarter: March 1
  • Summer quarter: May 15

The application should include:

  • Unofficial transcripts for all college-level work
  • A detailed 1-2 page Statement of Purpose via the online application. This should include a list of courses you plan to take, your interest in our department's graduate program, and your future goals.

For the "quarter and year you wish to enter," be sure to enter the quarter and year in which you plan to start taking classes as a GNM student, NOT when you plan to start the degree program.

  1. After submitting your application, please email bioadmit@uw.edu to notify us about the submission.
  2. You will be notified of the decision typically within 1-2 weeks.
  3. If you are admitted, follow the NM steps above for course registration (unless tuition exempt).

Space-Available Registration

Tuition-exempt students cannot register until the third day of each quarter, and other NM and GNM students are also not registered until the start of the quarter. Priority must be given to matriculated students, and seats cannot be reserved in advance. For Biostatistics courses with add code restrictions (see the Biostatistics Time Schedule for a > or Restr note to the left of the course SLN), after Registration Period I begins, see the course comment in the Time Schedule for procedures to be placed on an add code waitlist. BIOST 517 does not have add code restrictions.

Auditing Courses

To audit a course, you must have student status, obtain permission from the instructor, register for the course, and pay standard tuition and fees. Please review the UW policy on auditing classes.
