Exam Overview
MGTI examinations assess candidates' knowledge of applicable codes, standards, and practices. They follow ASSE Series 6000 (Professional Qualifications Standard for Medical Gas Systems Personnel) guidelines, NFPA codes, and relevant industry standards.
Exams consist of multiple-choice and true/false questions, with some certifications including written and practical components. Brazing certifications follow ASME Section IX standards.
Examination content, form length, and time limits are the same for a given certification regardless of whether you trained in person or online. The same prerequisites, application requirements, passing scores, and certification decision processes apply to both pathways.
Candidates are provided with the examination content outline for their certification before they sit the examination. Examination items themselves are confidential.

Proctoring
All MGTI certification examinations are proctored. A proctor may be MGTI personnel or a third party you designate. If you are examined online, you must designate a proctor before the examination is released to you; MGTI contacts that person and presents the proctor agreement for their acceptance.
No certification is issued until your proctor's attestation has been received and recorded. If no attestation is received, or your designated proctor declines to confirm, the certification is not processed and the matter is referred to the Program Administrator.
A supervisor, manager, or co-worker may serve as your proctor. A person may not serve if they are:
- A member of your immediate family
- Someone who stands to gain financially from your certification, beyond the ordinary interest an employer has in a qualified workforce
- Your instructor for the training that led to the examination
- Another candidate for an MGTI certification
- You
The full terms are published as the MGTI Proctor Agreement, which sets out what your proctor is asked to confirm and what MGTI records. Recertification examinations are not proctored — see Re-Certification.
Retaking an Examination
There is no waiting period. If you do not pass, you may retake the examination immediately. Every attempt is recorded in your record, and a re-examination fee applies to the second and third attempts.
You may attempt a given written examination up to three (3) times on one completion of approved training. If you do not pass on the third attempt, you complete approved training again, after which your allowance resets and you may again attempt the examination up to three times. Approved training for this purpose means training delivered by any instructor holding current ASSE 6050 certification — you do not have to repeat MGTI's own course.
This limit protects the integrity of the examination: repeated attempts at the same question bank allow its contents to be learned rather than its subject matter. It is not a penalty, and it is not a limit on how many times you may ultimately become certified.
Accommodations
MGTI is committed to equity in offering certification opportunities to people with disabilities and strives to make training and examinations accessible. Accommodations are available, and you are encouraged to ask.
Submit your request to MGTI before your examination is scheduled, saying what the disability is and what accommodation you are requesting. You may be asked to provide documentation from a licensed medical professional. Accommodations available for online examinations include, but are not limited to, extended examination time.
Your request is decided by the Program Manager within ten (10) business days of receiving the request and any supporting documentation. You will be told in writing what has been granted, or the reason it has not been. You are not required to schedule or sit the examination while your request is being decided, and a decision to decline an accommodation may be appealed. Requests are considered case by case and carry no additional cost to you.
MGTI examinations are administered at wheelchair accessible facilities. Proctors arranging a site notify MGTI whenever it is not possible to meet this or any other accessibility requirement.
Challenging a Question
You may challenge any question on any examination. If you are examined in person, complete the question challenge form provided in your examination package at the conclusion of the examination. If you are examined online, you may challenge a question directly within the examination interface at the time it is presented, by selecting a reason and providing a written explanation — submitting a challenge does not interrupt your examination and does not change your answer.
Each challenge is recorded and reviewed by MGTI. Where an actual error is found, it is corrected, the responsible Examination Committee is notified, and every affected examination score is adjusted accordingly. Provide as much reasoning and as many references as you can to support your challenge.
Fees & Registration
A fee applies to each certification examination and to the second and third attempts at a re-examination. Current pricing for every MGTI certification is published at medgascerts.com, which is the single source of truth for fees. Your examination fee must be received before you begin the examination, and it is separate from the cost of the required training, though a training provider may cover it.
Passing scores vary by certification, as set by the ASSE Series 6000 Standard, and are stated in the candidate handbook issued for each certification. Minimum scores for recertification are on the Re-Certification page.
Obligations that bind every candidate and certificate holder, including the confidentiality of examination content, are on the Standards of Conduct page.
