Certified Level of Rigor (LOR) Specialist Certification Program by Tonex
The Certified Level of Rigor (LOR) Specialist Certification Program by Tonex provides professionals with the technical knowledge and analytical skills required to determine, document, and justify software assurance rigor for safety-critical and mission-critical systems. Participants examine the relationships among Software Criticality Index (SwCI), Software Control Category (SCC), Level of Rigor (LOR), system hazards, software contributions, and assurance evidence.
The program explores the application of Military Standard 882E (MIL-STD-882E), Allied Ordnance Publication 52 (AOP-52), software assurance principles, and safety criticality classifications. Participants learn to perform complete LOR assessments, evaluate software control over hazardous functions, assign appropriate assurance activities, and develop defensible assessment documentation.
Cybersecurity is an important consideration because software vulnerabilities can influence hazardous system behavior, undermine safety controls, or compromise mission-critical functions. Participants examine how cybersecurity weaknesses, unauthorized software changes, and inadequate assurance evidence may affect software criticality and rigor determinations. The program supports integrated safety, software assurance, and cybersecurity decision-making throughout the system lifecycle.

Course Delivery
The Certified Level of Rigor (LOR) Specialist Certification Program is delivered through expert-led lectures, interactive discussions, structured workshops, technical exercises, and project-based learning. Participants receive access to supporting readings, assessment worksheets, standards-based references, and practical resources.
The program uses a practical training approach that includes exercises, real-world case studies, and examples of processes and documentation used in Level of Rigor assessment projects. Participants apply SwCI, SCC, LOR, MIL-STD-882E, AOP-52, software assurance, safety criticality, and cybersecurity concepts to complete defensible LOR assessments.
Assessment and Certification
Participants are assessed through quizzes, technical assignments, standards interpretation activities, LOR determination exercises, and a capstone assessment project. The capstone requires participants to evaluate software contributions to identified hazards, determine applicable SwCI and SCC classifications, assign the appropriate LOR, and prepare supporting documentation.
Upon successful completion of the program requirements and certification examination, participants will receive the Certified Level of Rigor (LOR) Specialist Certification from Tonex.
Question Types
- Multiple Choice Questions (MCQs)
- Scenario-based Questions
Passing Criteria
To pass the Certified Level of Rigor (LOR) Specialist Certification Program exam, candidates must achieve a score of 70% or higher.
