Frequently Asked Questions
What is the current AMT MLT exam format?
AMT identifies 210 four-option multiple-choice questions and a 3-hour limit. AMT states that unidentified unscored pretest items may be embedded. The exam is computer-based; current official material reviewed here does not establish a computer-adaptive format.
What score is required to pass AMT MLT?
AMT requires a scaled score of at least 70 on a 0–100 reporting scale. This criterion-referenced scaled score is not a statement that exactly 70% raw correct passes.
What is the current published pass rate?
The AMT Candidate Handbook reports that 64% of 562 MLT examinees passed in 2025. It is an annual aggregate, not a prediction for one candidate.
What happens after an unsuccessful attempt?
The candidate waits at least 45 days, applies and pays for retesting, and retakes the full examination. AMT limits a candidate to four lifetime attempts in one certification discipline.
Who is eligible for AMT MLT?
AMT publishes Education, Military, and Alternate Education routes. Each route has exact degree or semester-hour, laboratory-coursework, training, recent-experience, clinical-discipline, transcript, and verification requirements; applicants should use the current AMT route page.
How is AMT certification maintained?
An MLT certificant pays the annual renewal fee and completes 45 Certification Continuation Program points during each three-year CCP cycle.
