Website information
Updated October 19, 2026
This site introduces Five Factor Group and its ecosystem. Descriptions provide general information and invitations to discuss potential applications. Product availability, scope, pricing and delivery are established in the relevant proposal or agreement.
Scientific references describe the Big Five model or the specific instruments studied in those publications. They do not constitute validation of every Five Factor instrument. Personality information is interpreted alongside context and relevant evidence.
Five Factor materials, brands and content are subject to applicable intellectual property rights. Access to this site does not grant a commercial license, certification or accreditation. Permitted professional use is defined by the applicable agreement.
Professional photographs are illustrative. English cover previews are editorial adaptations and do not establish availability of translated questionnaires or reports. The Portuguese team product’s use of DNA is metaphorical.
Certification is issued by Five Factor Academy. Network inquiries begin an evaluation and do not grant accreditation, territorial rights or representation. Conditions are established for each professional, company or partnership relationship.
External websites may have different operators, languages, terms and policies. Sending an inquiry does not create a service contract. Contact us through the form for clarification about this website or a particular offering.
