The ISTO Test is a multiple-choice test aimed at establishing the level of understanding a candidate possesses in respect of a specific ISO management system standard (e.g. ISO 9001:2015). It focuses not only on understanding the requirements of a standard but is also designed to ensure that those who pass the Test have demonstrated a knowledge of the underlying management system principles, respective definitions and the standard' s practical implementation.
It is aimed at:
The Test consists of multiple choice questions with four (4) possible suggested solutions of which only one (1) correct or best alternative, which is the answer, and incorrect or inferior alternatives, known as distractors.
The ISTO test is a closed-book test however candidates are allowed to refer to an unmarked copy of the respective ISO standard which is the only permitted item during the test.
Candidates meeting the Pass criteria will be awarded a Certificate of Achievement. All candidates will receive an A C C U R A T E report indicating their level of understanding and relative ranking in each of the eight (8) domains. See Appendix I.
ISTO tests will be delivered electronically through an online e-assessment platform with AI invigilation, allowing candidates to take the test at their convenience, at their office or at home. In a physical location, it can be supervised by an invigilator.
We offer three levels of ISTO Tests for taking. By April 2024, we will be offering test-taking for Level 2.

Based on ISTO's research, endorsed by the ISTO Technical Advisory Board, the level of comprehension of an ISO management system standard can be grouped into eight (8) domains of understanding.
These form the acronym A C C U R A T E.
Ac: an Actual requirement in the standard related to documentation.
Co: Concept - the management principles on which the management system standard is based. This includes the sequence of activities as required in the standard.
C: the unique Clause reference of a specific requirement in the ISO management system standard
U: an Unspecified requirement in the standard (a requirement that does not exist).
R: a certain Requirement in the Standard (i.e. the text of the requirement).
A: the Applicability of the standard. This includes the intent of a requirement, and the scope of the standard.
T: Terms and definitions used in the standard. Generally these are defined in Clause 3 of each ISO management system standard. In the case of ISO 9001 QMS, terms and definitions are defined in the ISO 9000 standard.
E: an Erroneous requirement in the standard related to documentation.
