An Agricultural Laboratory Scientist III is the full performance level of work performing veterinary analytical, diagnostic, and epidemiological laboratory testing in compliance with applicable local, State and federal regulations and standards for the purpose of controlling and eradicating animal diseases.  Employees in this classification do not supervise other positions.  

Employees receive general supervision from a Veterinarian or other designated official.  The work is performed in a laboratory setting.  Employees are required to observe infection control precautions in order to prevent contamination and the spread of disease.  The work may require the lifting and moving of laboratory equipment and materials.              

Positions in this classification are evaluated using the classification job evaluation methodology.  The use of this method involves comparing assigned duties and responsibilities of a position to the job criteria found in the Nature of Work and Examples of Work Sections of the class specification.  

The Agricultural Laboratory Scientist I, Agricultural Laboratory Scientist II, and Agricultural Laboratory Scientist III are differentiated on the basis of the degree of supervisory control exercised by the supervisor over these employees.  The Agricultural Laboratory Scientist I performs duties under close supervision.  The Agricultural Laboratory Scientist II performs duties under close supervision at times and under general supervision at other times depending upon the complexity of the specific duty being performed.   The Agricultural Laboratory Scientist III performs the full range of duties and responsibilities under general supervision.   The Agricultural Laboratory Scientist III is differentiated from the Agricultural Laboratory Scientist Advanced in that the Agricultural Laboratory Scientist Advanced performs broader responsibilities of laboratory diagnostic and analysis work by conducting tests in multiple assigned areas, functions as a technical specialist in the testing of specific diseases, or in the use of the latest technological testing procedures.
