Basic Requirements for all grades, GS-5 and above

Degree: Successful completion of a full 4-year course of study in an accredited college or university leading to a bachelor's or higher degree that included a major field of study or specific course requirements in microbiology; or biology, chemistry, or basic medical science that included at least 20 semester hours in microbiology and other subjects related to the study of microorganisms, and 20 semester hours in the physical and mathematical sciences combining course work in organic chemistry or biochemistry, physics, and college algebra, or their equivalent.

Combination of education and experience: Courses equivalent to a major in microbiology, biology, chemistry, or basic medical science that included courses as shown above, plus appropriate experience or additional education. The quality of the combination of education and experience must be sufficient to demonstrate that the applicant possesses the knowledge, skills, and abilities required to perform work in the occupation, and is comparable to that normally acquired through the successful completion of a full 4-year course of study with a major in the appropriate field. In addition to courses in the major and related fields, a typical college degree would have included courses that involved analysis, writing, critical thinking, research, etc. These courses would have provided an applicant with skills and abilities sufficient to perform progressively more responsible work in the occupation. Therefore, creditable experience should have demonstrated similarly appropriate skills or abilities needed to perform the work of the occupation.

In addition to meeting the basic entry qualification requirements, applicants must have specialized experience and/or directly related education in the amounts shown in the table below:

Evaluation of Education: Microbiology is a broad field of science encompassing a number of scientific disciplines or areas of science, the fields in which this science is applied, and related fields where the work is concerned with or involves microbiology. The scientific disciplines or areas of this science include bacteriology, immunology, serology, algology, mycology, parasitology, protozoology, rickettsiology, tissue culture, virology, and similar disciplines or areas of science. The applied fields include environmental, food, dairy, soil, industrial, public health, clinical, and agricultural microbiology, and similar areas in which microbiology is applied. Related fields include taxonomy and systematics, plant, animal, or human physiology or pathology, infectious diseases, epidemiology, ecology, and similar areas of science where the work is directly related or applies to microbiology. Except where the course work deals with a limited and specific segment of the science, where it might be limited in usefulness, most of the work, including that dealing with the development and use of microbiological methods, procedures, and techniques, is qualifying. In interpreting the substantive value of the course work, credit may be given for courses in related fields, depending on the degree to which the courses are related to microbiological work.

Specialized Experience: Experience that equipped the applicant with the particular knowledge, skills, and abilities to perform successfully the duties of the position, and that is typically in or related to the work of the position to be filled. To be creditable, specialized experience must have been equivalent to at least the next lower grade level in the normal line of progression for the occupation in the organization.

Evaluation of Experience: For positions at GS-9 that involve a substantial amount of work in a specific specialized area or applied field of microbiology, at least 6 months of the experience must either have been in the appropriate area of specialization or applied field of microbiology, or have direct application in the area for which the applicant is being considered. For the GS-11 and higher grade levels of such specialized positions, the experience must have been sufficiently specialized to insure adequate familiarity with the area of specialization or applied field of microbiology, or have direct application in the area for which the applicant is being considered.
