| The
Essential Duties (EDs) are the foundation for the
subject matter on the certification tests. They
are developed by conducting a job analysis study
of a cross-section of wastewater agencies
representative of the entire industry. The Test
Content Specifications (TCSs) list the EDs and the
knowledge, skills, and abilities (KSAs) that are
associated with performance of the EDs. The
certification exam is designed to test a
candidate's KSAs and certify the competency of
those who meet or exceed a specified standard
(passing score).
The
certification Code of
Ethics sets an additional standard for
certification that certificate holders
meet, or exceed, minimum standards of competency
when performing the Essential Duties of the
certified vocation. This standard demonstrates
that certified professionals are dedicated to the
safe and effective performance of the vocation’s
Essential Duties.
