A class specification is a written description of each class position included in the classification plan. Specifications shall include a class title, a general statement of essential and non-essential duties and responsibilities, typical examples of duties performed, and minimum qualifications for entrance into a class. Special requirements, where appropriate, such as required licenses or certifications, shall also be included. A class specification shall be considered only as a descriptive guideline and not as inclusive of all duties to be found in a position allocated to a particular class.
