Dissertation research credits (ECON 999)


Dissertation Research credit (ECON 999) is taken by students who have advanced to candidacy. Students working on dissertation research (999) must register for a minimum of 3 credits of 999 per semester (excluding summers) until they have completed the minimum number of credits of 998 and 999 required by the university and the PhD ECON program. Then, they must register for one credit of 999 until the dissertation is complete and has been officially submitted to the library. Course registration numbers (CRNs) change every semester, so dissertation research students must request a new code each semester.


Instructions for Requesting CRNs

  1. You must use your Mason email account to request this code. No replies will be made to non-Mason email accounts.

  2. To request a code, you must email egibson5@gmu.edu with the following information:

  • full name
  • G#
  • discipline (Economics)
  • dissertation advisor
  • number of credit hours requested
  • copy of email approval from your dissertation advisor (for initial and for continuous enrollment requests)  

 3.  After the Economics Graduate Studies Office receives your email request and all is in order, we will send you the code for ECON 999.

Any requests that do not meet the above requirements will not be acknowledged.

Any requests for exceptions to the above must be submitted in writing to the Director of Graduate Programs, Professor Carlos Ramirez.


Other Relevant Information

Doctoral students must be advanced to candidacy before they may enroll in ECON 999.

Enrollment in three (3) credits of 999 is considered full-time.

Once doctoral students begin registering for 999, they must enroll in at least 3 credits of 999 each semester (excluding summers) until they have completed the total number of dissertation credits required on their individual program of study.

Once enrolled in 999, all doctoral students must maintain continuous enrollment in 999 until they deposit their approved dissertation in the University Library. Students who fail to maintain continuous registration are required to pay for missed credits during the semester that they return.

If they have completed the number of dissertation credits required on their program of study, they may maintain continuous enrollment by registering for only one credit of 999

No late enrollments after the last day to add each semester will be approved.

These courses are graded IP until the dissertation has been successfully defended, at which time they are changed to S.
