1. TestStand Certification Overview

The National Instruments TestStand Certification Program consists of the following two certification levels:

  • Certified TestStand Developer (CTD)
  • Certified TestStand Architect (CTA)

The Certified TestStand Developer (CTD) certification represents core knowledge and skill in the design, development, and integration of production tests in the TestStand environment. A CTD demonstrates the following competencies in TestStand:

  • Apply concepts, definitions, and configuration options
  • Utilize TestStand data storage and data passing mechanisms
  • Develop and debug tests using standard development environments

A CTD is a test developer who uses the TestStand framework to develop, analyze, debug, and deploy tests. The CTD certification is for developers who possess technical expertise in a certain product and wish to distinguish their TestStand knowledge, skills, and experience in test development.

CTDs may advance their credentials by gaining knowledge and experience in developing and customizing TestStand frameworks and distinguish themselves by attaining the CTA certification.

Refer to the How Can I Prepare for the Certified TestStand Architect Exam?  document for more information about the CTA exam.

Note The CTD certification is a prerequisite to taking the CTA exam. There are no exceptions to this requirement.
