The College of Professional and Global Education is pleased to offer a one-year post-baccalaureate training program for Clinical Laboratory Scientist (CLS).

Designed to address the critical shortage of clinical laboratory scientists, the Clinical Laboratory Scientist 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).

The California State University, Los Angeles is accredited by the WASC Senior College and University Commission (WSCUC), among other accrediting agencies. For more information, please visit CSU Accreditation & State Authorization.

Professional Licensure and Certification

California State University programs for professions that require licensure or certification are intended to prepare the student for California licensure and certification requirements. Admission into programs for professions that require licensure and certification does not guarantee that students will obtain a license or certificate. Licensure and certification requirements are set by agencies that are not controlled by or affiliated with the California State University and licensure and certification requirements can change at any time.

The California State University has not determined whether its programs meet other states’ educational or professional requirements for licensure and certification. Students planning to pursue licensure or certification in other states are responsible for determining whether, if they complete a California State University program, they will meet their state’s requirements for licensure or certification.
