  • “Creating an uncertainty budget from start to finish can be an intimidating challenge. Mr. Hogan has created a systematic, step by step approach that breaks the process down into easier to understand concepts. Each lesson is clear and concise, with excellent examples and tools that walk the student through the process of building an uncertainty budget. I highly recommend the course.”

  • “This course is accessible to students and thorough. Mr. Hogan explains the calculations well as he walks the students from the introductory concepts of uncertainty to the completion of an uncertainty budget ready for submission for ISO 17025 approval. I greatly appreciated his focus on developing a robust uncertainty budget that was defensible to auditors, and on many occasions pointing out common problem areas that assessors flag. The documentation is first rate and will provide a valuable reference.”

  • “The course was well taught by Richard, he did a great job of watering down the confusing points to point out what they really are looking for in those sections. The course helped clear up a lot of things for me and I will be strongly recommending to others who are interested. I really enjoyed how this course was taught and how the schedule went. Richard is also very easy to get in touch with to ask any questions.”

This course is jam-packed full of powerful information that is not taught in any other course. I will show you exactly how to do everything step by step in simple and practical ways. Each process that you will learn works and has actually been used in labs that are ISO/IEC 17025:2017 accredited.

No one else teaches a process. They teach theory! The same stuff you could learn for free if you pick up and read the GUM, the UKAS M3003, or the NIST Technical Note 1297. Except, you are paying them to read it to you with a few PowerPoint slides!

I do things much differently! I teach theory too, but cover so much more information. Additionally, I teach step-by-step processes that allow you to estimate uncertainty just by following instructions. Plus, you get to watch me perform each process so there is no doubt about how to do it.

I am literally going to help you master the process of estimating measurement uncertainty.

Finally, I will show you how to meet ISO/IEC 17025:2017 requirements, including creating uncertainty budgets, drafting a scope of accreditation, calculating CMC Uncertainty equations, and reporting uncertainty. Each of these processes is critical to getting accredited. You can’t get accredited without them! Yet, no other course teaches it.

So, the choice is yours. Do you really want to learn how to estimate uncertainty or do you want to say that you have had training but have no clue what to do?

If you want to learn how to estimate measurement uncertainty, join this course and let me teach you. Check out the information below to see what is included.

    It is recommended to have access to test equipment and calibration reports in order to perform an uncertainty analysis during the course.


    What do I do if I need help?

    If you have a question related to this course, email [email protected]. I will be your instructor throughout the course. As a student, you have direct, personal access to me anytime you need help!


    How long is the course?

    Plan to take about 3 days to 3 weeks to complete the course. Some people complete the course in 3 days. Most complete it in 21 days.

    There are 28 videos totaling over 9 hours of video content. Most videos are 15–30 minutes long, with the shortest video around 6 minutes and the longest about 43 minutes.


    Can I pay with PayPal?

    Yes. On the checkout page under the “Billing Information” section, select the “Pay with PayPal” button. This will allow you to pay with PayPal.


    Can I pay with a Purchase Order?

    Yes. You can pay using a purchase order with NET 30 terms. Submit purchase orders to [email protected]. Once approved, students will be manually registered and login information will be emailed directly to the student. To manually register students, we will need the name and email address of each student to create an account and email login information.


    Is there a discount for multiple students?

    Yes. There is a group discount when 3 or more students join the course. Email [email protected] for a quote to receive the group discount.


    I need to get approval first, will you hold the sale price for me?

    Yes. Make sure to email [email protected] and let us know that you are waiting on approval to purchase the course. We will hold the sale price for you until you receive approval. Once approved, notify us and we will send you a private link to buy the course at the sale price.

  • When does the course start and finish?

    The course is offered periodically throughout the year. Typically, we offer training about every other month. Make sure to join our mailing list to receive notifications when the enrollment is available. Once you have enrolled, you have ongoing access and assistance from me. The course is self-paced and you may take as long as you need to complete it.


    Can I join the course just to use the videos as a reference?

    Yes. You can join the course only to use it as a reference. You do not have to complete the course (although, we recommend you do). Plenty of students join the course only to help them as they create uncertainty budgets for an audit. That is why you get access to the course for 1 year.


    Can I use this course to train other employees/coworkers?

    Yes. You can use this course to train more than one employee or coworker. While you should purchase training for each employee, We cannot tell who is logged into your profile. So, feel free to use your account to train more than one employee. However, only the registered student will receive a training certificate after the course is completed.


    Can I transfer my course seat to another employee/coworker?

    Yes. You can transfer your account to another employee or coworker. For any reason, if you are unable to participate in the training and have not completed the course, you can transfer your seat to another employee or coworker. Make sure to notify me and I will create an account for the new student.


    Can I preregister for the course?

    Yes. You can preregister for the course. If you cannot join us for the current training session, you can register for a future class. Just email [email protected] to request a quote and an electronic invoice.


    Can I repeat the course as many times as I like?

    Yes. You can take the course as many times as you like. You get 12 months access to the course and repeat it an unlimited number of times during your one year period.


    Is this course video on demand or live webinars?

    The courses are video on demand, so you can watch the videos any time you like. However, the instructor is available to answer questions and offer help for the first 30 days. This includes email and telephone calls. If help is needed via a live webinar, an additional fee may be required.


    Why don’t you offer these courses all the time?

    Courses are only offered certain times of the year (usually once a month or every other month) because students get access to instructor help for the first 30 days. You can take the off schedule if you like, but you will pay the full price for the course.


    Why is your course more expensive than other uncertainty courses?

    The courses are more expensive for 3 reasons; value, the amount of information, and access to the instructor for help. Our courses have a lot more information than other courses (about 5 to 7 times the amount of information). Some competitor courses require you to take two courses to complete measurement uncertainty training which together is more expensive than one of our courses, but still does not have nearly the amount of information that we offer. My course is the only course available that will teach you how to meet ISO/IEC 17025 requirements (e.g. CMC Uncertainty equations, draft a scope of accreditation, etc.) and A2LA R205 requirements.
