The Safety Trained Supervisor (STS) certification provides a means for employers to verify safety and health knowledge of first-line supervisors and managers. The program requires applicants to meet minimum education and experience requirements and demonstrate knowledge of basic safety and health standards and practices.
The STS certification program is intended for individuals who:
  • Are managers at any level.
  • Are first line supervisors of work groups or organization units.
  • Have a safety responsibility for a work group that is part of other work duties.

The STS workbooks cover the exam blueprint material that could possibly be tested. Each workbook contains a series of self-evaluation sessions using the same question, answer and explanation format as in the workshop and the Online Learning Management System membership. The material included in the self-evaluation sessions is designed to supplement study initiatives and reinforce those areas where emphasis is needed for the examination. The program will provide you with over 300 researched questions, answers and, more importantly, explanations based on the contents of the exam blueprint.

Safety Trained Supervisors are not safety specialists or safety practitioners. Typical candidates have a safety responsibility that is adjunct, collateral or ancillary to their job duties. Their main job duties are in a craft or trade, in leadership, supervision or management, or in a technical specialty. If safety responsibilities involve a greater portion of job duties, the role is more likely to be that of a safety technician/technologist or safety professional.

The typical STS helps an employer implement safety programs at the worker level through supervisory, safety committee or similar safety and health leadership roles. Safety tasks often include monitoring for job hazards, helping ensure regulatory compliance, training employees in safety practices, performing safety record keeping tasks, coordinating corrections for safety problems within or among work groups, and communicating with safety specialists or management.

The STS program is nationally accredited by the National Commission for Certifying Agencies (NCCA).

Eligibility and Examination

To gain eligibility for a STS examination, you must be of good moral character and meet the following three requirements:
  • Have two years of experience in any industry or in the industry related to the version of the STS examination to be taken.
  • Have one year of experience as a supervisor or safety leader of a work group. Examples are manager, foreman, crew chief, superintendent, or member of a safety committee. This experience can be concurrent with Requirement #1. If you are training to become a supervisor or safety leader and do not have the one year of experience, you can substitute two additional years of industry experience in Requirement #1.
  • Have completed 30 hours of formal safety training through a single course or multiple training courses.
