The certification
Most injury work starts after someone is hurt. CWIS is built for the clinician or safety professional who works inside the workplace, where the risk builds, and helps the organization act on it.
Worksite injury prevention
The CWIS path covers injury prevention program design, early intervention and injury first aid within OSHA recordability rules, post-offer employment testing, and injury prevention built into new hire onboarding, on top of the shared Foundation.
Courses & certification
Every Matheson certification starts with the same four Foundation courses. Complete them once and they count toward CEES, CEOS, CWIS, and CRTW. Take the full certification track or individual courses for continuing education. Each course page has the full syllabus, formats, and CE credits.
Shared by CEES, CEOS, CWIS, and CRTW.
Understand the mechanisms behind workplace musculoskeletal disorders and how to identify, prevent, and address them in clinical and worksite settings.
Explore the psychological and social dimensions of workplace injury and recovery, and integrate evidence-based strategies into return-to-work planning.
Learn to quantify the physical and cognitive demands of any job and systematically match worker capabilities to job requirements.
Master the data-driven tools and metrics used to analyze injury trends, measure prevention effectiveness, and communicate results to stakeholders.
Then the CWIS path
Learn to design and implement practical worksite injury prevention programs that address organizational needs and improve worker outcomes.
Implement evidence-based early intervention strategies that reduce severity, duration, and cost of workplace injuries.
Learn to develop job-specific employment testing that safely and defensibly matches worker abilities to essential job demands.
Learn to integrate injury prevention, job-specific education, and safe work practices into the new hire onboarding process.
Apply the full CWIS curriculum to realistic workplace cases and develop practical, integrated solutions for injury prevention and workforce performance.
Complete knowledge checks across the track, then submit one Job Demands Analysis report and one Post-Offer Employment Test you have built. A Matheson instructor reviews both against Matheson credentialing criteria. Submissions that meet the standard earn the CWIS credential.

Who it's for
Clinicians who work on site, and the safety, HR, and operations people who keep a workforce healthy.
Courses are open to anyone doing this work. Certification requirements are set out on the CWIS page.
Resources
How work injuries happen, where the rules draw the line, and why trust is part of the intervention.
How work injuries happen, how injury data shows where to start, what a prevention program includes, and what keeps it working.
What does this worker need, and what do the rules require me to do?
That is why rapport is not just a soft skill in worksite injury prevention. It is part of the intervention itself.
Upcoming
Live worksite training on the Matheson schedule, in person or by live stream where offered.
The best injury is the one that never happens. Matheson training prepares you to find where risk is building, act early, and build programs the workplace keeps.
