The College of Professional and Global Education is pleased to offer a one-year post-baccalaureate training program for Clinical Laboratory Scientist. Designed to address the critical shortage of clinical laboratory scientists, the Clinical Laboratory Scientist (CLS) Certificate Program has established partnerships with a consortium of clinical laboratories for the required bench training. The CLS program will provide both didactic and practical clinical training in hematology, clinical chemistry, blood banking, microbiology, and immunology to prepare students to sit for the State of California CLS licensing exam (American Society of Clinical Pathology MLS exam).
