Science Technician Job Description

A Science Technician in government does the hands-on work that turns a science program's plan into data. The job sits under a project scientist or program manager at a federal bureau, a state environmental or agriculture department, a county health lab, or a municipal water utility, and it follows that office's discipline: stream chemistry, soil testing, plant pest surveys, air monitoring, wildlife counts. O*NET lists the plain title "Science Technician" under Life, Physical, and Social Science Technicians, All Other (SOC 19-4099), its catch-all for technicians not counted in a named technician occupation.

In the federal workforce the title splits into two personnel series run by the Office of Personnel Management. The Biological Science Technician series (0404) covers support for life-science programs; OPM notes that the specialized experience for some of these positions is normally work performed in a controlled environment, such as research activity, control program work or nursery growing. The Physical Science Technician series (1311) credits experience in fields that include astronomy, physics, geophysics, chemistry, hydrology, health physics, engineering, electronics, geology, oceanography and metallurgy. The Interior Department sums up its 0404 work as gathering and processing samples, testing soil or water for toxins, and identifying and propagating native plants.

In the field

Field technicians go where the measurements are. A U.S. Geological Survey description of its hydrologic technicians has them installing gages, checking routine gage functions and troubleshooting equipment malfunctions, and heading out during and after a flood as soon as it is safe so the data keep flowing. Between site visits they review records against USGS accuracy standards. The USGS Water Data for the Nation site publishes data collected by automated sensors alongside "field measurements" taken during site visits; groundwater-level reference readings, for example, are used primarily to calibrate automated sensors. USGS set July 1, 2026 as the date the site would begin publishing reference readings for all parameter codes, a change it said would make field measurement data available for the first time for new parameters such as reservoir elevation and water temperature.

In the lab

Lab days are about controlled, repeatable procedure. A technician receives samples, checks preservation and holding times, prepares standards and blanks, runs the analysis, and logs results and quality-control checks in the lab information system. Labs that use hazardous chemicals fall under OSHA's laboratory standard (29 CFR 1910.1450), which applies to employers engaged in the laboratory use of hazardous chemicals and centers on a written chemical hygiene plan.

Why the paperwork is part of the science

Government data end up in permits, cleanup decisions, outbreak responses and sometimes court. A missing calibration entry or a gap in chain of custody can make a valid result unusable. The technicians who do this job well treat field forms, instrument logs and data flags as part of the measurement itself, and they tell the scientist about an odd result the day they see it.

Education

For federal jobs, OPM's qualification standards spell out what counts. In both the 0404 and 1311 series, the entry grades accept college study in place of experience: for GS-3, one year of study that included at least 6 semester hours of scientific or technical courses; for GS-4, two years of study with at least 12 semester hours in that kind of coursework. For GS-5, the 0404 standard asks for a full 4-year course of study leading to a bachelor's degree, with a major in a relevant subject or at least 24 semester hours in the listed science and math courses. As a rough guide, an associate degree or a couple of years of science coursework fits the lowest technician grades, and a bachelor's in chemistry, biology, geology, environmental science or a related field fits the upper ones.

State and local governments set their own classification specs, and they vary by civil service system. Read the minimum qualifications line in the job class specification rather than assuming federal rules carry over.

Experience

OPM accepts specialized experience instead of education for GS-4 and above. The 1311 standard also credits work as a laboratory mechanic or in a trade or craft when it was performed in close association with physical scientists. Useful preparation includes undergraduate research, a seasonal field crew, a water or wastewater lab job, a university greenhouse or a state park survey crew. Typical guidance: one to three years of hands-on work for the middle grades, more for lead or crew-boss roles.

Training and credentials

• HAZWOPER training under OSHA's 29 CFR 1910.120 for assignments at hazardous waste sites or cleanup operations.
• Lab safety training under the employer's chemical hygiene plan, required for labs covered by OSHA's 1910.1450.
• Medical Laboratory Technician, MLT(ASCP), from the American Society for Clinical Pathology Board of Certification, for technicians who want to move into clinical testing at a public health laboratory.
• Agency-specific trainings such as boat operation, wilderness first aid and defensive driving.

Skills that get used every week

• Instrument operation and basic troubleshooting: meters, sondes, balances, spectrophotometers, chromatographs.
• Standard methods: EPA methods, USGS field manuals, and the lab's own SOPs.
• Data handling: LIMS entry, spreadsheets with QC flags, and enough R or Python to clean a field dataset.
• GIS and GPS for locating and documenting sample sites.
• A valid driver's license and comfort working outdoors in heat, cold and rain, sometimes for multi-day trips.

The occupation as a whole

O*NET projects average growth of 3% to 4% for Life, Physical, and Social Science Technicians, All Other over 2025-2035, with about 11,200 openings a year on average. Those figures describe the whole occupation, not only government jobs. BLS counted 73,910 jobs in the occupation nationally in May 2025, with a median wage of $62,280.

Government is a distinct slice of that picture. In the BLS federal, state and local government row, the occupation held 8,510 jobs in May 2025. Pay differed by level of government: the median was $73,240 in the federal executive branch, $66,520 in local government and $46,660 in state government. Counting every life, physical and social science technician occupation together, that government row held 79,540 jobs.

Federal hiring after 2025

Executive Order 14356, signed Oct. 15, 2025, required each agency head to set up a Strategic Hiring Committee to approve the creation or filling of each vacancy, and it requires federal hiring to be consistent with the Merit Hiring Plan. Under that order, a technician vacancy needs the committee's approval before it is created or filled. The requirement was still in place in late 2026: an OPM final rule published Oct. 29, 2026, and effective Nov. 30, 2026, writes the Strategic Hiring Committee into federal personnel regulations at 5 CFR part 250.

The EPA also shrank. Its Office of Inspector General reported that in July 2025 the EPA announced a workforce reduction of nearly 23 percent, from 16,155 to 12,448 staff, and that the final stage of its reorganization became effective Nov. 16, 2025. Among the changes, the agency moved Office of Research and Development scientific staff to program offices and set up an Office of Applied Sciences and Environmental Solutions.

Federal pay rose modestly. Executive Order 14368, signed Dec. 18, 2025, set a 1.0 percent across-the-board raise for January 2026 and kept locality pay percentages at 2025 levels. On the 2026 base General Schedule, before locality pay, GS-5 step 1 is $34,799 and GS-9 step 10 is $68,549.

State and local labs

APHL's 2026 Laboratory Workforce Profile, based on 2,009 lab staff who responded to a convenience-sample survey, found that the end of grant funding emerged as a notable new reason for workforce departures in 2026. A separate APHL survey found that as of fall 2025, 66% of laboratories reported moderate to heavy impact from funding uncertainty on data modernization projects. Instrument interfacing was the most common modernization activity, with 69% of laboratories actively working on it; APHL lists efforts such as interfacing critical instrumentation with LIMS for automated result transmission.

Where the job leads

Technicians who finish the coursework for a professional series can move into biologist, chemist, hydrologist or physical scientist positions. Others stay on the technical track as lead technicians, field crew leaders, quality assurance coordinators or lab supervisors. The skills that carry across every one of those moves are clean data, documented methods and instruments that work when the season starts.

Dear Hiring Committee,

I am applying for the Science Technician opening in the Plant Industry Division at the [State] Department of Agriculture. I earned a B.S. in Plant and Soil Science from [University] in May and spent the last two summers on a seasonal survey crew for the division's invasive insect program, so I already know your trap routes and your data sheets.

On that crew I set and serviced more than two hundred sticky and lure traps across three counties, logged every trap check on the division's tablet app, and bagged and labeled suspect specimens for the diagnostic lab. Midway through my second season I noticed that GPS points for a cluster of traps had drifted because a tablet was set to the wrong coordinate system. I flagged it to the crew lead, we re-shot the points the next morning, and the lab was able to match every specimen to its correct location before the quarterly report went out.

In the campus soil lab I prepared extracts for nutrient analysis, ran samples on the spectrophotometer, and kept the calibration log that our lab manager reviewed each week. I learned to treat a blank that reads high as a reason to stop, not a number to note and move past.

I am interested in this permanent role because it combines the field survey work I enjoy with the lab identification and data review I want to get better at. I hold a valid driver's license, I am comfortable with long days outdoors, and I have completed the department's pesticide safety training.

Thank you for considering my application. I would welcome the chance to talk about how I can help keep the survey season running on schedule.

Sincerely, [Your Name]
