Most GD&T courses feel overly technical or hard to apply. This one’s different.

We focus on a practical framework that covers 95% of what you’ll actually use in industry, explained in plain English. You’ll learn not just what the symbols mean, but when to use them, why they matter, and how to apply them confidently in your job — not just pass a test.

No GD&T experience needed — but you should be comfortable reading basic engineering drawings. If not, we recommend starting with our Print Reading & Tolerances course first.

This course teaches a simple, practical GD&T framework that covers 95% of what you’ll actually use on the job. It's designed to eliminate confusion, boost clarity, and help you solve real manufacturing problems.

You’ll learn how to:

• Understand why GD&T matters — and how it prevents miscommunication between teams

• Apply all 14 major GD&T symbols and know when not to use them

• Use feature control frames to clarify design intent and inspection criteria

• Apply datums throughout a part’s lifecycle: from design to inspection

• Interpret GD&T on real drawings and physical parts without overcomplicating things

If you’ve ever had a part rejected, misquoted, or misunderstood due to unclear tolerancing — this course will help you prevent that from happening again.

This course is designed for anyone who needs to read and apply GD&T in real-world settings. Whether you're just getting started or have been exposed to GD&T already — this course brings clarity.

You’ll benefit if you’re a:

• Mechanical or design engineer

• Inspector or inspection planner

• Machinist or CNC operator

• Tooling or quality engineer

• Buyer, manager, or salesperson who needs to interpret GD&T correctly

If you’ve ever second-guessed a feature control frame or struggled with inconsistent or confusing prints, this course will eliminate that uncertainty.

You should have a basic understanding of how to read engineering drawings. If you're not confident in that yet, we recommend starting with our Print Reading & Tolerances course first.

No prior GD&T knowledge is required.

This course is not an official prep course for the ASME GDTP Certification exam, but it can absolutely help you build the skills and knowledge that employers — and the exam — expect.

Here’s what you can expect from GD&T Fundamentals:

• A certificate of completion you can use for training records or resumes

• Practical GD&T knowledge directly applicable to job roles in design, inspection, quality, and manufacturing

• Confidence interpreting real drawings — a skill many job descriptions list but few people actually master

For those aiming to take the ASME GDTP Technologist- or Senior-Level Exams, we recommend our Expert Bundle, which combines three courses:

• Print Reading & Tolerances (covers general tolerancing, symbology, and drawing standards beyond GD&T)

• GD&T Fundamentals (your core framework for interpreting and applying GD&T)

• Advanced GD&T (covers advanced concepts such as Resultant Condition, Composite Controls, and Advanced Datum Features)

These courses together cover much of the material you’ll see on the exam and give you access to instructors for questions along the way.

It’s important to note:

• Both GDTP exams are based on the ASME Y14.5 Dimensioning and Tolerancing Standard, not just GD&T

• Up to 25% or more of the exam covers the scope of the standard, general tolerancing, and non-GD&T symbology — which is why Print Reading & Tolerances is so helpful

Finally, no matter which course you take, the best way to prepare is to use the ASME Y14.5 Standard itself alongside your training. Reading the standard cover to cover will go a long way in helping you pass.

We’ve also published free resources to guide your preparation:

• ASME GDTP Exam Overview

• Technologist vs. Senior-Level GDTP Exam

If you have questions about which course or path is right for you, feel free to reach out — we’re here to help you prepare.

The course is designed to be “standard agnostic,” meaning we focus on the core principles of GD&T that apply no matter which standard you follow.

That said, our training is primarily based on the ASME Y14.5 standard, since that’s the most widely used in North America. Wherever appropriate, we also point out key differences between ASME and ISO standards — so that you understand where things diverge.

This approach ensures that:

• You’ll get a clear and practical understanding of GD&T, no matter what industry you work in

• The training is not narrowly confined to one version or standard

• You’ll be able to apply what you learn in both ASME and ISO environments

• Whether your organization follows ASME, ISO, or a mix of both, the core concepts taught in this course will still apply to your daily work.

This course includes real-world exercises and examples, so you can apply what you're learning immediately.

You’ll:

• Work through drawing-based exercises that reinforce each concept

• See how GD&T shows up on real parts and prints

While it’s not “hands-on” in the sense of using tools, it’s far from theoretical — it’s focused on real application, not textbook memorization.

If you've ever dealt with:

• Parts rejected because of unclear, too tight tolerancing

• Misunderstandings between design, production, and inspection teams

• Uncertainty about how to interpret a feature control frame

...this course is for you.

By learning GD&T through this simplified framework, you’ll:

• Communicate clearly across design, inspection, and manufacturing

• Avoid costly rework, scrap, or missed deadlines

• Know exactly which tolerances matter — and which don’t

• Make better decisions, faster — and with more confidence

We’re here to help you apply what you’ve learned — not just finish the course.

• If you enroll in the online course, you’ll have full access to the learning platform for 1 year after enrollment. Even after you complete the training, you can revisit the lessons anytime for review or as a reference on the job.

• If you complete the course with a live instructor, you’ll receive 90 days of platform access after the training wraps up — including everything available in the online version.

Included with both formats:

• Access to previously recorded webinars and bonus video content

• Extra practice examples and tips

• Direct email support from certified GD&T instructors for real-world questions

Whether you're reviewing a concept for a project or facing a tricky drawing at work, we’re here to help long after the course ends.
