What is the ASCP Board of Certification exam?
The ASCP Board of Certification (BOC) exam is a credentialing test administered by the American Society for Clinical Pathology for laboratory professionals in the United States. It certifies medical laboratory scientists, technicians, phlebotomists, histotechnicians, and specialists, validating their competency to work in clinical laboratory settings.
What is the format of the ASCP certification exam?
The ASCP exam uses computer adaptive testing (CAT), meaning question difficulty adjusts based on your responses. It is administered at Pearson VUE test centers and consists of multiple-choice questions with one best answer. The adaptive format ends once the system determines your ability level with statistical certainty.
How many questions are on the ASCP MLS exam?
The ASCP Medical Laboratory Scientist (MLS) exam contains a maximum of 100 questions, delivered adaptively within a 2 hour 30 minute time limit. Other certifications like MLT have up to 100 questions in 2 hours 30 minutes, while phlebotomy technician exams include 80 questions in 2 hours.
What score is needed to pass the ASCP exam?
Candidates need a scaled score of 400 or higher to pass any ASCP Board of Certification examination. Scores are reported on a scale from 0 to 999, with 400 set as the minimum passing standard. Results are provided immediately after completing the exam at the testing center.
