Fit testing is the requirement that most often gets discovered late — usually the week a clinical site asks for documentation nobody has. It's also one of the easiest to solve permanently: we bring the testing to your campus, run the cohort in a morning, and drop every result straight into your compliance portal.
What the rule actually says
OSHA's respiratory protection standard, 29 CFR 1910.134, requires that anyone using a tight-fitting respirator be fit tested before initial use, whenever a different respirator size, style, model, or make is used, and at least annually thereafter. Students reach that requirement through their clinical affiliation agreements rather than as employees, so the exact rule is set by your program and its clinical partners — and it does vary. Boise State's School of Nursing requires annual fit testing for NIOSH-approved N95 respirators as required by the clinical facility, and gives students at least one appropriately sized respirator after a passing test. Others differ: the University of Washington School of Medicine strongly encourages annual certification but does not mandate it, and the University of Toronto's nursing faculty updates mask fit every two years. Clinical scenarios that trigger N95 use include caring for patients with suspected or confirmed tuberculosis, influenza, varicella, and other airborne-transmissible illnesses.
The step almost everyone forgets: medical evaluation first
Under OSHA's standard, a medical evaluation comes before fit testing and respirator use — typically the OSHA Respirator Medical Evaluation Questionnaire. Schools bake this into the process: UMass Amherst requires students to complete the questionnaire and a request for medical evaluation before being scheduled, and OHSU assigns an OSHA Respirator Survey that must be completed before a fit-testing appointment, noting that certain conditions such as poorly controlled asthma may make N95 use unsafe. If your program schedules fit testing without collecting medical evaluations first, that's a gap worth closing before a clinical partner asks about it.
How our on-site fit testing events work
- $25 per student, performed on your campus — no student travel, no clinic appointments, no chasing paperwork.
- Qualitative fit testing (QLFT), the standard pass/fail method for N95 filtering facepieces, with roughly 15–20 minutes per student including the comfort assessment OSHA requires.
- Consequences are real, so documentation matters. Boise State's policy states that a student without an appropriately fit-tested N95 may not care for patients requiring that protection — and if every patient in the setting requires one, the student is sent home for the day. Another program charges make-up fees for clinical time missed over missing fit-test documentation.
- Documentation lands in your portal automatically — every student's result, date, and expiration tracked with the rest of their compliance file, with automatic reminders before the annual re-test comes due.
- Stack it with a drug screening event. We regularly run fit testing and drug collection on the same visit ($25/student each) and clear two requirements for an entire cohort in one morning. More students on one visit is better value for everyone.
- Coverage: strongest across the Southeast and Midwest, with travel available beyond — ask us about your campus.
Why programs stop doing this in-house
Programs that run their own fit testing usually discover the same three costs: a faculty member's morning disappears, the documentation lives in a binder no clinical site can audit, and nobody tracks the annual expiration until a student gets turned away at a rotation. Outsourcing the event and centralizing the record fixes all three at once — and it's the same portal that already tracks immunizations, TB tests, drug screens, and background checks.

Frequently asked questions
Do nursing students really need N95 fit testing?
Yes, when clinical sites require respirator use. OSHA's standard (29 CFR 1910.134) requires fit testing before initial use, whenever a different size, style, model, or make is used, and at least annually after that. For students the requirement arrives through clinical affiliation agreements, so specifics vary: Boise State requires annual fit testing as required by the clinical facility, while some schools encourage rather than mandate annual re-testing. Follow your program's policy.
How often does fit testing have to be repeated?
At least annually under OSHA's standard, and sooner if there's a change affecting the seal — significant weight change, facial surgery, scarring, or major dental work. Many clinical facilities also re-test on their own schedule.
What is a qualitative fit test (QLFT)?
A pass/fail test that relies on the wearer's ability to taste or smell a test agent while wearing the respirator. It's the standard method used for N95 filtering facepieces in student and healthcare settings, and it's what we perform at on-site events.
How long does it take per student?
Plan on roughly 15–20 minutes per person, which includes time to judge comfort as OSHA requires. A cohort of 60 students is comfortably a morning's work for our team.
Does facial hair affect the test?
Yes. Facial hair along the sealing surface interferes with the seal and is one of the most common reasons a person can't pass a fit test — OHSU's guidance notes that even one day of stubble will prevent a good seal. Students should arrive clean-shaven along the seal area. Schools typically offer accommodation pathways for religious grooming practices and disability-related needs.
What does it cost?
$25 per student at an on-site campus event. Combine it with an on-site drug screening event ($25/student) and you clear two requirements for an entire cohort in one visit.
