National Occupational Standards – Environmental Employment



As environmental employment continues to develop and mature, defining the scope of environmental work activities and competencies becomes essential for effective human resource planning and workforce development. Ensuring a strong foundation and common language for environmental employment is among the most critical issues for the success of the entire environmental industry.

National Occupational Standards (NOS) are competencies required to perform successfully in a particular occupation. They describe the standard acceptable skills and knowledge required of environmental professionals in the areas of core knowledge, transferable competencies, and technical skills.

Note: We have included small updates to the basic NOS since the 2011 report. If you require a precise list of the current NOS, please contact us:
