1. About the service
SDTEST® is a behavioral intelligence platform built on Spiral Dynamics theory (Beck & Cowan, ISBN-13: 978-1405133562). It provides individual assessments, access to a global behavioral dataset, and simulation tools for organizational decision-making.
2. The assessment
The SDTEST® assessment consists of 5 statements, each with response options that decode the statement. You must select exactly three options in order of importance, those that most closely correspond to your interpretation of the statement.
- The assessment is free and may be taken an unlimited number of times.
- Each result is stored on a unique link sent to your email address.
- Results are anonymized and aggregated into the global SDTEST® dataset.
3. Intellectual property
SDTEST® is a registered unitary mark (USPTO, WIPO), comprising a unique combination of the abbreviation of "Spiral Dynamics" and the word "test." All platform content, datasets, correlation matrices, and SD-Navigator™ simulation models are the intellectual property of SDTEST®.

4. Acceptable use
By using this service, you agree to:
- Use assessment results for personal, research, or organizational purposes only.
