Worksite Injury Prevention Training & Certification

Matheson teaches worksite injury prevention as one connected process. Professionals learn to document the job as it is actually performed, act early on symptoms within OSHA first aid rules and their professional scope, design programs from the employer's own data and operating realities, and connect prevention to stay-at-work and return-to-work planning. The CWIS credential is awarded on review of a Job Demands Analysis and a Post-Offer Employment Test the applicant has built.

Candidates complete the CWIS certification track: Workplace Injury Mechanisms & WMSDs, Psychosocial Factors in Work Injury and Recovery, Job Demands Analysis, Using Injury Data to Drive Prevention, Worksite Injury Program Design, Early Intervention and Injury First Aid, Post Offer Employment Testing (POET), Injury Prevention in New Hire Onboarding, and Worksite Injury Solutions Capstone. They complete knowledge checks across the track, then submit one Job Demands Analysis report and one Post-Offer Employment Test they have built, which a Matheson instructor reviews against Matheson credentialing criteria. CWIS is valid for 3 years, and recertification follows the same submission process.

No. Under 29 CFR 1904.7(b)(5)(iv), a treatment on OSHA's first aid list is first aid regardless of the professional status of the person providing it, including a physician or other licensed health care professional. Care that goes beyond the list is medical treatment no matter who provides it. First aid is also only one part of recordability: days away from work, restricted work or job transfer, loss of consciousness, and the other recording criteria can make a case recordable on their own.

It depends on why it is done. OSHA's May 2, 2024 enforcement guidance says exercise or stretching conducted for purely precautionary purposes, such as a general program for workers without symptoms, is not medical treatment. Recommending exercise or stretching to treat a work-related injury or illness, at work or at home, is medical treatment and makes the case recordable, regardless of who makes the recommendation.

Yes, when it is used on its own. In a July 6, 2015 letter of interpretation, OSHA stated that kinesiology tape and other elastic taping fall within its definition of first aid, reversing a 2014 interpretation. Orthopedic devices with rigid stays, or other devices designed to immobilize a part of the body, remain medical treatment.

A job demands analysis documents the essential functions of a job and how the work is actually performed: weights and forces handled, how often and for how long, postures and positional tolerances, mobility, reaching and handling, cognitive demands, and the work environment. The information comes from interviews with workers and supervisors, direct observation, measurement, and job documentation, and is recorded in consistent, measurable terms so clinicians, employers, and insurers read it the same way.

It can be either. EEOC guidance treats physical agility and fitness tests as not medical examinations unless they measure physiological responses, such as heart rate or blood pressure. A medical examination after a conditional job offer is permitted only if everyone entering the same job category is examined, the results are kept confidential in separate medical files, and any criteria used to screen someone out are job-related and consistent with business necessity (29 CFR 1630.14(b)). State law can add requirements, so employers should review a testing program with employment counsel.

They rely on the same reference: the documented demands of the job. The job demands analysis defines those demands. A post-offer employment test checks the essential physical demands of a specific job. Early intervention and stay-at-work planning compare a worker's current abilities with them, and return-to-work planning uses them to set and progress modified duty. When the job demands analysis is sound, each later step has a defensible basis.

Clinical skill is the starting point. Working on site also means knowing OSHA recordkeeping and where first aid ends, professional scope and state practice rules, how to analyze job demands, how to read injury data, and how to communicate with safety, human resources, operations, and supervisors. The CWIS track is built around those skills, on top of the shared Foundation in injury mechanisms, psychosocial factors, job demands analysis, and injury data.

Yes. The four Foundation courses are shared by CEES, CEOS, CWIS, and CRTW, so a completed Foundation counts toward CWIS, and you continue with the CWIS Framework courses and Capstone. Only current Blueprint Foundation courses count; Matheson training from before 2026 does not. CWIS has its own fieldwork review.
