In 1985, Alex Krulikowski began a small start up company that provided training and consulting in a little-known discipline called geometric dimensioning and tolerancing. Twenty-five years later, Effective Training Inc. has evolved into a corporation that provides GD&T training, products and services to organizations across the globe.
Alex and ETI would like to thank our clients for supporting us for the past 25 years. We look forward to providing you with GD&T products and services in the future. Please take advantage of our gift to you: 25% off selected products and services.



I’ve had many clients ask me what’s new in the ASME Y14.5-2009 Standard. As you can imagine, a standard that has been 15 years in the making contains numerous changes. There are over 20 new or revised symbols and over 40 new or revised terms. In fact, almost every paragraph of the standard has some revision.
ETI is celebrating the new year with the largest company-wide sale in our 24-year history.
