Testimonials from Candidates

Taking the ISTO Test of Understanding was a wonderful exercise, requiring the analysis and interpretation of the standards in a natural and professional way. The cases presented varied from everyday routine situations right up to very technical questions, which makes the exam as globally applicable as the standards themselves. 
Alicia Robles Gomez
ISO 9000 and Standardization Manager, TELMEX Telefonos de Mexico, Mexico
ISTO was a very good test to evaluate my understanding of ISO9000. While working as a consultant and a registrar auditor, I have seen many misunderstandings about ISO9000 by quality staff, consultants, and even registrar auditors... Understanding the standards is a most important factor, and ISTO is making a success by deploying that purpose in its TESTs.
Nobuharu Hiyoshi
Independent Consultant / Sub-contracted Auditor, Tokyo, Japan
Very valuable for consultants in supporting and demonstrating their understanding of the important aspects of the changes.
David Underwood

The ISTO Test of Understanding is a significant first step towards identifying people who can help managers apply ISO 9000 in ways which create powerful management systems.

I found the ISTO TEST to be an excellent diagnostic tool to measure my level of understanding of the standards.
