Roots of Deen

The history of Deen dates back to 1937, when L. Deen established himself as an independent consultant in Rotterdam, as one of four pioneers in the field of recruitment and selection. In 1987, Deen transferred his activities to Drs. G.P. Hazelzet, who took over the office. Subsequently, the organization was taken over and expanded by Drs. Frank P. Hazelzet and Dr. Gertrude Smit. Since then, Dane has developed into a well-established player in the industry, with a comprehensive range of services that includes online and offline assessments, Executive Search & Recruitment and Management Development. At Deen, quality comes first and this is confirmed by our preferred partner contracts and high reliability & quality of advice over a long to very long period of time.

Based on scientific research

Company Stars was developed on the basis of scientific research and is based on the latest insights and developments in the field of personality psychology. The goal was to develop a psychometric instrument that can support organizations in the development and selection of managers, sales account managers, professionals and (management) teams.

Company Stars was developed by a team of experienced psychologists and drs. FP. Hazelzet who have each earned their spurs in the field, making the test based on a wide range of knowledge and insights. This team has spent years researching key personality dimensions and how they affect behavior and performance. Through this in-depth knowledge of personality and behavior, Company Stars is able to help organizations select the best candidates for a position and develop managers and professionals.

The scientific research behind Company Stars is constantly evolving and is regularly updated based on new insights and feedback & data from buyers. This allows Company Stars to continue to meet the high standards we set for our scientific instruments and provide our customers with the most current and reliable testing information.

What sets Company Stars apart:

Company Stars differs from other test providers in that it explicitly positions itself in the higher-quality segment of the market. The Company and Management Stars tests replace in some cases the traditional assessment that does not take place online making it an ideal choice for companies looking for a high-quality testing solution at an affordable price.

In addition, Company Stars is unique in that it is based on decades of experience and has been continuously improved based on input from customers and academia.
