BSHS in Medical Laboratory Science


The Blended BSHS with a major in Medical Laboratory Science (MLS) is a degree completion where you transfer in 60 credits from a regionally accredited college or university and then complete 60 credit hours at GW for a total of 120 credit hours divided into four degree components:

  • General Education (38 credit hours)
  • Electives (22 credit hours)
  • MLS Major Courses (54 credit hours)
  • Online Writing Courses (6 credit hours)

Students must complete at least 60 credit hours of GW coursework to meet the academic residency requirements for the online program.


Courses in the major (Phase I) are designed to broaden the student's foundation in the sciences in preparation for the clinical phase of the program (Phase II). All courses are taught online, with the exception of the four months of clinical practica and labs completed at the Virginia Science and Technology Campus in Ashburn, VA.

To maintain the academic integrity of the program, the GW MLS program requires that students use a web-based remote proctoring system called Remote Proctor Now in every MLS-designated course throughout the program.  Additional information on this system from Software Secure, Inc. can be found at this address:  See below the IT requirements to use Remote Proctor Now.

The clinical practica (Phase II) are usually taken on a full-time basis. Students are typically in a clinical laboratory eight hours per day (daytime hours), five days per week.  Admitted students must be able to fulfill the necessary time requirement for the practica.

GW Course Offerings

Students complete courses in a lock-step format.  All of the didactic courses (Phase I) in the MLS programs are taught online, with the exception of the face-to-face labs, which are taught in Ashburn, VA.  The lab courses typically take place on weekday evenings and students will need to make sure to keep this time free in order to complete the labs.  The clinical practicum is also taken in-person, at an assigned location.
