Body Of Knowledge - 2021 Survey

The Professional Certification Program (PCP) of the SWS is accredited by the Council of Engineering & Science Specialty Boards (CESB). CESB accreditation requires that the PCP create and maintain a Body of Knowledge (document) that outlines specific skills, knowledge, and abilities that a Professional Wetland Scientist should possess. The Body of Knowledge (BoK) must be solicited from all who are certified by the program and be updated every five years. The BoK is a living guidance document for knowledge and skill requirements to be used by the PCP Certification Review Panel in assessing an applicant's experience towards certification as a Professional Wetland Scientist.

The Certification Standards Committee developed a questionnaire that was sent to all PWSs. The questionnaire consisted of a list of skills, abilities and knowledge all PWSs could potentially possess in order to be certified as a Professional. All PWSs were asked to rank each area relative to their importance for being a certified Professional Wetland Scientist. Ranking was from 1 to 5, with 1 being not important and 5 being most important.

The survey results given here represent the full current assessment of the PWS Body of Knowledge as of 2021 to be updated in five years. These results will be developed into a hierarchy of knowledge and skills used by the Certification Review Panel as part of an objective method to assess an applicant's experience.

Ratings are 1 being not important to 5 being most important.
