The 5th Special Forces Group (Airborne) at Fort Campbell, KY requires a one-year license agreement for a comprehensive cognitive performance assessment system. The system must be a computer-based testing platform measuring at least thirteen cognitive domains with millisecond precision, and must include all necessary hardware, software licenses, secure data storage, and consultation services. Testing protocols must be scientifically validated with demonstrated test-retest reliability. This is a brand-name requirement for the "S2 Cognition" system, and offerors must propose exactly that product. Quotes for alternate or "equal" products will not be accepted.
