CharacterIX Personality Inventory at a Glance

In order to understand the differences between people's thoughts, feelings and behaviors and the reasons behind these differences and to ensure that people realize their potentials at the highest level, we started CharacterIX Personality Inventory's R&D works in 2011. With a well-equipped team of psychologists, authors, reporting experts and educators, we have turned our product, a living organism which we constantly develop including its measurement and evaluation process, into a professional system through a comprehensive process of scientific work.

CharacterIX is a next-generation inventory independent of cultural differences with three different question sets (White Collar, Blue Collar, Professional Orientation) that work with a smart algorithm. Thanks to these characteristics, it is an adaptable and comprehensive personality assessment and evaluation tool that can be applied to individuals from different cultures. It is in use since 2015, and hundreds of thousands of personal reports have been created. A study of validity and reliability was conducted with 21,140 people, and universal and scientific research works that will be of high value are currently being carried out. We recommend CharacterIX Personality Inventory to everyone who wants to know oneself and understand others and to all dynamic institutions and organizations that have a desire for growth and a mission to invest in people.
