Finally, a measurement uncertainty training course for accredited chemistry laboratories.

This course is a complete introduction and application of estimating uncertainty in chemistry. It is best suited for chemical testing labs that perform sample analysis using high-performance liquid chromatography, gas chromatography, and mass spectrometry. Students should expect to learn all of the concepts and techniques needed to estimate measurement uncertainty, create uncertainty budgets, and report uncertainty in test reports.

It is a comprehensive measurement uncertainty training course that teaches much more than other courses. The goal of this course is to take you from zero to expert using easy step by step instructions and demonstrations, so you can prepare for ISO/IEC 17025:2017 accreditation.

The key things that you will learn in this course are:

  1. Statistically, analyze your own data and processes
  2. Estimate measurement uncertainy using the GUM method
  3. Create uncertainty budgets
  4. Report uncertainty in test certificates

This is an online class based on the EUROCHEM guide and the Guide to Estimating Uncertainty in Measurement (GUM). Additionally, it teaches ISOBudgets’ unique 7-step process to estimate uncertainty in measurement; a repeatable system that will help you estimate uncertainty for almost any process.

You will learn the exact same processes that I use to estimate uncertainty.

Rick Hogan


I’m an expert at estimating uncertainty. Here’s how I can help you.

I’ve been estimating uncertainty in measurement since 2008. Over the years, I have developed simple and clever ways to calculate measurement uncertainty.

In 2010, I developed a systematic process to estimate measurement uncertainty that works and no one else teaches it! Since then, I have used this same process to perform more than 3,000 uncertainty analyses for my customer’s laboratories. Now, I am teaching you the exact process that I use.

When you read most measurement uncertainty guides, you get overwhelmed by all of the information. They are not clear on teaching you exactly what steps you should take to complete an uncertainty analysis.

Most measurement uncertainty training courses are good at teaching you the GUM method, but fail to show you how to find sources of uncertainty and estimate their contribution to uncertainty. Furthermore, none of them teach you how to prepare for ISO/IEC 17025 accreditation. I think that is insane! Especially for the courses offered by an accreditation body. Sure, the accreditation bodies have guides to help you develop your scope of accreditation, but why don’t they offer training to show you how to draft your scope.

In this course, I have fixed all of that!

You will learn EVERYTHING you that need to know to actually estimate uncertainty, create an uncertainty budget, and prepare your scope of accreditation for ISO/IEC 17025:2017.

I have spent years listening to my customers and documenting their problems and complaints. Then, I used that information to create the most comprehensive measurement uncertainty training course available today.

Now, I am offering this training to you. My goal is to give you the information, processes, and tools you need to estimate uncertainty for ISO/IEC 17025 accreditation.

Join my course and let me teach you how to estimate measurement uncertainty like a pro.


Completing this course and learning how to estimate uncertainty is a pretty simple process. Just follow these 4 steps:

  1. Login to access the course,
  2. Watch the lectures,
  3. Watch the demonstrations,
  4. Start estimating uncertainty,



This course is recommended for laboratory personnel that will that need to estimate uncertainty to create uncertainty budgets and develop the scope of accreditation for ISO/IEC 17025 accreditation. Here is a list of the most common people that join my courses:

  1. Quality Managers,
  2. Technical Managers,
  3. Quality Control Personnel,
  4. Technicians,
  5. Engineers.

Most laboratories train one person to estimate measurement uncertainty. In my experience, it is best to give measurement uncertainty training to at least 2 people so you are covered in case someone leaves the company or retires.




  • “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.”

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.


Here’s a Final Note (Just in Case You Scrolled to the Bottom).

This is a measurement uncertainty training course for chemistry laboratories that need to estimate uncertainty and create uncertainty budgets for ISO/IEC 17025:2017 accreditation. It has more information than any other measurement uncertainty training courses (available from your accreditation body). My processes are easier to learn and I will show you how to estimate uncertainty (other courses do not offer this). After completing this course, you should expect to be able to easily analyze your own data, estimate uncertainty, create uncertainty budgets, and report uncertainty in your test reports.

But you are free to choose any measurement uncertainty training you like. Whether you want to teach yourself or take a training course with your accreditation body, please pick the learning path that works best for you.

However, I would love for you to join this course. You will learn 10X more in less time. I guarantee it!

The choice is yours.
