The CLS Preparatory Program offers the required coursework, as well as many elective courses, to strengthen your application to competitive CLS training programs. Start here on your journey to becoming a clinical laboratory scientist—increasingly in demand as the need grows for professionals to perform sophisticated clinical diagnostic tests with a high degree of skill and knowledge.


There are no prerequisites for the Clinical Laboratory Scientist Preparatory Program, but a bachelor’s degree in biology or chemistry is highly recommended.

Curriculum Requirements

The curriculum comprises 2 core courses (6 semester units) and 1–2 electives or an additional core course (3 semester units) for a total of 9 semester units (at least 135 hours of instruction).

Core courses are those that are usually required for entry into certified CLS training programs; electives are either recommended for these programs or provide additional relevant science background. Candidates must pay a nonrefundable program registration fee.

You must take all courses for a letter grade. To receive the Award of Completion, you must maintain an overall minimum 2.5 grade point average, with a grade of C or better in each course. All coursework must be completed within five years of registering for the program.
