There are only a few good and scientifically well-documented enneagram tests available on the global market. No test has yet been fully accepted within professional psychological test environments. However, as the first in the world, Enneagram Business Profile has received a quality certification from DNV in Scandinavia. This means that the tool is research-based and meets high quality standards in accordance with European guidelines for psychological tools (EFPA). The tool also fulfils the requirements of the Danish Certification Council for Test Use. How did we succeed in achieving this? In 2021, we established a collaboration with an international research team, which in their pre-analyses validated the internal consistency at 0.77. Within personality type tests, this is regarded as confirmation of a qualitatively sound test. The 180 carefully selected questions are the result of three years’ work identifying the differences, traits and characteristics of each of the nine types. This means that our test measures what it sets out to measure, and that the internal consistency ensures that the different parts of the test are coherent and measure the same underlying concept. This provides users with confidence in the test’s reliability and relevance – which is essential for both practical application and further research. Between 2022 and 2024, our research team conducted a large empirical and global study in collaboration with a foreign university, where the test was compared against already validated tools – Diversity Icebreaker (www.diversityicebreaker.com) and the personality test Big Five. The results showed consistency with the Big Five in line with previously published studies. Content, discriminant and confirmatory validity analyses were conducted. Meaningful differences related to age and gender were also identified. Since the Enneagram Business Test is particularly aimed at the business sector, it was also relevant to demonstrate differences in results between managers and employees. Our research team continues to carry out ongoing studies to ensure that the Enneagram achieves greater recognition within an empirical psychological framework. In future studies, the focus will be on test–retest reliability as well as validation against external criteria. The DNV certification is valid until 2030. In the certification process, particularly positive feedback was given regarding user materials and the training of practitioners. The Enneagram Business Test is based on the following books by Edit Moltke-Leth: The Enneagram & Team Development, Knowledge Sharing, Leadership and Collaboration (bestseller in 2002) The Enneagram & The Intelligent Organisations of the Future (2013
