It is expected that 8-12 students will be accepted into the CLS training program each year.  The application deadline for the fall class is January 1st and the deadline for the spring class is September 1st. The applicant must demonstrate a strong interest and motivation in Clinical Laboratory Sciences; have a B.A. or B.S. degree with a GPA of 3.0 or greater both overall and sciences; complete the prerequisite courses of Analytical Chemistry, Immunology, Physics, Biochemistry, Medical Microbiology or Pathogenic Bacteriology, and Hematology 2-3 months before starting the training program; and obtain a valid trainee license from the State of California. For UC Davis students only, if you have taken Chemistry 2 ABC series, you have satisfied the coursework requirement for Analytical Chemistry.

Course now available: In order to assist applicants in meeting the California required hematology course pre-requisite, UC Davis Extension now offers a hematology course (link).  This hematology curriculum was specifically structured to meet the needs of the CLS trainee applicant and will provide them with hematology instruction required to enter a CLS training program.

Laboratory Field Services (LFS) has determined that some course work completed at Weber State University does not meet established requirements.

     - LFS will no longer accept the following courses completed at Weber State University after June 1, 2014.


The state required course work is approved by the State of California Public Health Department, LFS as they grant final approval prior to issuing the required CLS Training License.  LFS may be reached at (510) 620-5793, 5795, or 3801 to inquire about specific coursework prior to taking a class to meet CLS training requirements.
