CST BSMIC Exam Day - What to Expect
Microbiology accounts for 6 of the 150 scored questions on the CST exam (about 4.0%), one of the smallest domains. It reinforces infection prevention concepts tested throughout the rest of the exam, so strong BSMIC understanding pays off beyond its own question count.
What to Bring to Pearson VUE
- Valid, unexpired government-issued photo identification matching your NBSTSA record.
- Your exam confirmation details.
- Nothing else - personal belongings are stored before you enter the testing room.
How BSMIC Content Appears
- Identifying which link of the chain of infection a specific practice interrupts.
- Distinguishing antisepsis from disinfection in a described scenario.
- Recognizing why spore-forming organisms require sterilization rather than high-level disinfection.
- Standard precautions and PPE selection for a described patient care scenario.
Pacing Strategy
With 175 total questions in 240 minutes, average about 82 seconds per question. BSMIC contributes only about 6-7 questions, so move through this content efficiently and preserve time for larger domains.
Managing Uncertainty
If a BSMIC question feels unfamiliar, think in terms of the chain of infection framework - identifying which link is being described or interrupted usually points you toward the correct answer, even for an unfamiliar specific scenario.
After the Exam
A provisional pass/fail result appears immediately after you finish. Your official NBSTSA score report follows within a few days, with a domain-level breakdown provided if a retake is needed.
