I need help in deciding what kits to sign up for - what kind of help can I get?

Let us help you develop a plan based on your scope and your needs. NAPT staff develops hundreds of plans each year for our members. Let us work on your plan next.

Why is NAPT nonprofit?

Simple answer: NAPT could not provide the services it does to the metrology community without it being nonprofit.  Only because of the numerous sponsors, the donation of the kits, the volunteering of the technical advisors that assist in the design of the schemes and the one on one help given to members are we successful.  All this could only happen in a nonprofit environment. In short, NAPT exists because of the metrology community supporting the services NAPT provides back to the metrology community.

What’s the difference between a proficiency test (PT) and an interlaboratory comparison ( ILC)?

An Interlaboratory Comparison (ILC) looks at measurement results between several laboratories. The purpose of an ILC could be to evaluate methods, different standards, environmental effects, competency of staff or the lab, or other factors in the measurement process. A proficiency test (PT) is designed to evaluate competency or proficiency, and is a type of ILC.

Does NAPT follow PT plans created in the Customer Portal?

While you can create a detailed plan in your NAPT customer portal, it is the responsibility of the participant to notify us which kits they want to actually enroll in.

How many kits can I sign up for at once?

The web site was designed to allow participants to enroll in three kits at once, which is the most common number.  Please contact NAPT directly when requesting more than 3 kits so we can apply all discounts you are entitled to for multiple enrollments.

Why should I use NAPT vs. other proficiency testing providers?

When you compare NAPT against other metrology PT providers, you will find there really is no comparison. Compare NAPT’s full time staff to other PT providers who conduct PTs as a side job.  Compare the ability to get technical advice from 50 plus metrology experts, quality of expertise, and the best customer portal of any PT provider. Further, your data submittal will be compared to 100 other like organizations. AT NAPT, we love to say to new participants “We Dare You to Compare NAPT vs them” and you too will see there is no comparison!

You don’t offer a kit that I need - what are my options?

We can acquire an artifact and design a kit to meet your needs, we can work with you on conducting your own intras ILC/PT and/or you can use the exact same application we use and conduct your own intra laboratory comparisons.

I need more information about QMS Navigator. Where can I get it?

Try out our online demo, consult with our technical staff who designed the app, or with our lead programmer – set up personal webinar by contacting NAPT staff and let them know your preference.

Can you tell me who else participated in this proficiency test?

No, we cannot. The participants are anonymous and may not be disclosed by NAPT. Please do not reach out to other labs you may know that are enrolled as that would be a violation of your enrollment.

What types of kits do you have?

NAPT services the metrology and test community and most of the kits offered are based on the needs of those participants. Our list of kits, including the disciplines are listed on the NAPT website. Please visit the website and use the user friendly sort tool to find the kit you need, or feel free to contact NAPT directly and we will help you find the kit that best fits your needs.

Why doesn’t NAPT have their Accrediting Body's symbol on their reports?

NAPT has participants who are accredited by all the accrediting bodies and because of that, NAPT has a long-standing policy that we do not advertise for any one accreditation body - we like them all.  Also, NAPT is accredited to ISO 17043 so all of NAPT reports are recognized and accepted by all accreditation bodies.

Does NAPT ship its kits outside of North America?

No. NAPT does not ship outside North America. As an alternative, you may want to consider using the QMS Navigator as a helpful tool for your proficiency testing needs.

What are NAPT’s hours of operation?

NAPT staff is available from 8:00 a.m.-5:00 p.m. Central Standard Time.

I haven’t received my kit and I have my audit coming up. Can you help?

Yes, NAPT can provide you with a letter noting that you are signed up for a kit and the expected date you will be receiving the kit.

My lab is outside of the USA - why do I have to pay for the importing and exporting of a kit?

Shipping kits to labs outside of the continental USA comes with additional costs. Because of these additional costs, all international participants are required to pay their share of importing, exporting, taxes, and fees that come with shipping a kit. NAPT tries its best to alleviate costs by scheduling international kits together.  

What is the lead time of a kit?

Some kits are scheduled months out, others three to four weeks. It’s best to contact staff via a quick call or send an email to napt@proficiency.org with your need and staff will get back with you ASAP.   

Will my accreditation body accept reports issued by NAPT?

NAPT reports are recognized and accepted by all the leading accreditation bodies.

Is NAPT accredited?

NAPT is an ISO/IEC 17043 accredited provider. NAPT Is the only proficiency test provider that can meet all of your needs via our offerings of proficiency tests. You can review our scope of accreditation on this site.

We are very proud of our accreditation, but we believe there is more to being a first-class proficiency testing provider than just being accredited.  Our level of service, number and variety of tests offered, and quality of value added proficiency tests are just a few examples of why NAPT is the clear choice when selecting a PT provider. We would ask you to compare the services that NAPT offers against other providers and after comparing everything we have to offer, you will see there really is no comparison.
