Certified NASA Human-Rating Engineering Professional (CNHREP) Certification Program by Tonex
The Certified NASA Human-Rating Engineering Professional (CNHREP) Certification Program by Tonex provides a structured professional foundation for engineers, safety specialists, program leaders, and technical professionals responsible for developing, evaluating, verifying, and supporting human-rated space systems. The program addresses human-rating philosophy, crew protection, certification planning, lifecycle reviews, safety analysis, human-system integration, verification and validation, and certification evidence using National Aeronautics and Space Administration (NASA) requirements and technical standards as primary references.
Participants examine how engineering decisions support crew safety, failure tolerance, safe recovery, crew control, situational awareness, human health, and performance throughout the system lifecycle. The program emphasizes disciplined requirements interpretation, traceability, risk management, objective evidence, and certification readiness.
Cybersecurity is increasingly important to human-rated systems because digital command, control, communications, avionics, software, and ground interfaces can influence safety-critical functions. Effective cybersecurity engineering helps protect the integrity, availability, and authenticity of information and control paths supporting crew safety. Participants learn to consider cybersecurity risks alongside system safety, reliability, human performance, and operational assurance.
