Pay Grade: 24



This is specialized, professional work in chemistry in a laboratory.

Work involves conducting a variety of standardized chemical and physical tests on an assortment of different sample matrices. Work involves the application of analytical procedures to determine the qualitative and quantitative makeup of chemical compounds or the application of physical tests to determine the physical attributes of substances.

Standard Classification Factors

Supervision Received - LEVEL B: "Under general supervision…" Employees working under general supervision usually receive some instructions with respect to the details of most assignments but are free to develop their own work sequences within established procedures, methods and policies. They are often physically removed from their supervisor and subject to only periodic checks.

Difficulty - LEVEL B: Average… Where the employee is confronted with a variety of duties susceptible to different methods of solution which, in turn, places a correspondingly higher demand upon resourcefulness and concentration. Positions which require the analysis and evaluation of raw data and the rendering of conclusions would, in many instances, fall into this category.

Complexity - LEVEL B: Work is of a structured nature including duties that have several related steps. This level involves simple analysis of data, identification of easily distinguishable facts and recognition of differences in related situations. Workers at this level exercise limited independent judgment in determining methods or procedures to be used in making minor decisions. Work is normally controlled by frequent review and consultation with supervisors. When guidelines exist at this level, they are usually specific and aid in determining an approach to problems or situations. Workers at this level must be able to identify basic differences in situations to determine the actions which need to be taken.

Consequence of Actions or Decisions - LEVEL C: Consequences of actions or decisions at this level are limited in scope and effect as the work is reviewed occasionally. Errors may cause moderate inefficiency. Costs due to errors may be significant.

Contacts - LEVEL A: The purpose of the contact is to obtain, clarify, give or screen established factual information, regardless of the type (i.e., easily understood or technical) within a well-defined relationship. Normal communication skills are required.

Physical Demands - LEVEL B: The work requires light physical exertion. The employee may be required to perform handling activities with lightweight or easily moved items (e.g. books, file folders, boxes of office supplies, small machine parts, etc.); perform moving activities for brief periods; operate light equipment; perform repetitive motions for brief periods; confined to a work area.

Environmental Conditions - LEVEL B: The work environment involves moderate hazards, risks or discomforts. Exposure to minor deviations from pleasant environmental conditions is normal. Minor to serious injuries are possible.

Supervision/Leadership - LEVEL A: No supervisory or leadership responsibility; may explain work instructions or assist in training others.
