GDTP (Y14.5) - Geometric Dimensioning and Tolerancing Professional Certification

Advance your career with two professional certifications to demonstrate your GD&T proficiency!

ASME's GDTP (Y14.5) Professional Certification Program provides a means to demonstrate proficiency in the understanding and application of the geometric dimensioning and tolerancing (GD&T) principles expressed in ASME’s widely-applied Y14.5 Standard. Those principles form an essential element of the design language for mechanical engineering.

Two levels of GDTP certification for each Y14.5 standard:
The GDTP – 1994 Technologist level - measures an individual’s ability to understand (“read”) drawings that have been prepared using the language of GD&T, as defined in the Y14.5M – 1994 Standard.

The GDTP – 1994 Senior level - measures an individual’s ability to select and apply (“write”) geometric controls to drawings as defined in the Y14.5M – 1994 Standard.

The GDTP – 2009 Technologist level - measures an individual’s ability to understand (“read”) drawings that have been prepared using the language of GD&T as defined in the Y14.5–2009 Standard.

The GDTP – 2009 Senior level - measures an individual’s ability to select and apply (“write”) geometric controls to drawings as defined in the Y14.5 – 2009 Standard.

For more information regarding this GDTP (Y14.5) Professional Certification Program, the requirements for certification and pertinent financial considerations as you progress through this application process, please review the Application Information Handbook.
