Science technicians use the principles and theories of science and
mathematics to solve problems in research and development and to help
invent and improve products and processes. However, their jobs are more
practically oriented than those of scientists. Technicians set up,
operate, and maintain laboratory instruments, monitor experiments, make
observations, calculate and record results, and often develop
conclusions. They must keep detailed logs of all of their work-related
activities. Those who work in production monitor manufacturing processes
and may be involved in ensuring quality by testing products for proper
proportions of ingredients, for purity, or for strength and durability.
As laboratory instrumentation and procedures have become more
complex in recent years, the role of science technicians in research and
development has expanded. In addition to performing routine tasks, many
technicians also develop and adapt laboratory procedures to achieve the
best results, interpret data, and devise solutions to problems, under
the direction of scientists. Moreover, technicians must master the
laboratory equipment so that they can adjust settings when necessary and
recognize when equipment is malfunctioning.
The increasing use of robotics to perform many routine tasks has
freed technicians to operate more sophisticated laboratory equipment.
Science technicians make extensive use of computers, computer-interfaced
equipment, robotics, and high-technology industrial applications, such
as biological engineering.
Most science technicians specialize, learning skills and working in
the same disciplines in which scientists work. Occupational titles,
therefore, tend to follow the same structure as those for scientists. Agricultural
technicians work with agricultural scientists in food, fiber, and
animal research, production, and processing. Some conduct tests and
experiments to improve the yield and quality of crops or to increase the
resistance of plants and animals to disease, insects, or other hazards.
Other agricultural technicians do animal breeding and nutrition work. Food
science technicians assist food scientists and technologists in
research and development, production technology, and quality control.
For example, food science technicians may conduct tests on food
additives and preservatives to ensure FDA compliance on factors such as
color, texture, and nutrients. They analyze, record, and compile test
results; order supplies to maintain laboratory inventory; and clean and
sterilize laboratory equipment.
Biological technicians work with biologists studying living
organisms. Many assist scientists who conduct medical research—helping
to find a cure for cancer or AIDS, for example. Those who work in
pharmaceutical companies help develop and manufacture medicinal and
pharmaceutical preparations. Those working in the field of microbiology
generally work as lab assistants, studying living organisms and
infectious agents. Biological technicians also analyze organic
substances, such as blood, food, and drugs, and some examine evidence in
a forensic science laboratory. Biological technicians working in
biotechnology labs use the knowledge and techniques gained from basic
research by scientists, including gene splicing and recombinant DNA, and
apply them in product development.
Chemical technicians work with chemists and chemical
engineers, developing and using chemicals and related products and
equipment. Generally, there are two types of chemical
technicians—research and development technicians who work in
experimental laboratories, and process control technicians who work in
manufacturing or other industrial plants. Many research and development
chemical technicians conduct a variety of laboratory procedures, from
routine process control to complex research projects. For example, they
may collect and analyze samples of air and water to monitor pollution
levels or produce compounds through complex organic synthesis. Most
process technicians work in manufacturing, where they test packaging for
design, integrity of materials, and environmental acceptability. Often,
process technicians who work in plants also focus on quality assurance:
there, they monitor product quality or production processes and develop
new production techniques. A few work in shipping to provide technical
support and expertise for these functions.
Environmental science and protection technicians perform
laboratory and field tests to monitor environmental resources and
determine the contaminants and sources of pollution. They may collect
samples for testing or be involved in abating, controlling, or
remediating sources of environmental pollutants. Some are responsible
for waste management operations, control and management of hazardous
materials inventory, or general activities involving regulatory
compliance.
Forensic science technicians investigate crimes by collecting
and analyzing physical evidence. Often, they specialize in areas such as
DNA analysis or firearm examination, performing tests on weapons or
substances such as fiber, hair, tissue, or body fluids to determine
significance to the investigation. They also prepare reports to document
their findings and the laboratory techniques used, and may provide
information and expert opinion to investigators. When criminal cases
come to trial, forensic science technicians often provide testimony, as
expert witnesses, on specific laboratory findings by identifying and
classifying substances, materials, and other evidence collected at the
crime scene.
Forest and conservation technicians compile data on the size,
content, and condition of forest land tracts. These workers usually work
in a forest under the supervision of a forester, conducting specific
tasks such as measuring timber, supervising harvesting operations,
assisting in roadbuilding operations, and locating property lines and
features. They also may gather basic information, such as species and
population of trees, disease and insect damage, tree seedling mortality,
and conditions that may cause fire danger. Forest and conservation
technicians also train and lead forest and conservation workers in
seasonal activities, such as planting tree seedlings, putting out forest
fires, and maintaining recreational facilities.
Geological and petroleum technicians measure and record
physical and geologic conditions in oil or gas wells, using advanced
instruments lowered into wells or by analysis of the mud from wells. In
oil and gas exploration, these technicians collect and examine
geological data or test geological samples to determine petroleum and
mineral and element composition using scanning electron microscopes.
Some petroleum technicians, called scouts, collect information
about oil and gas well drilling operations, geological and geophysical
prospecting, and land or lease contracts.
Nuclear technicians operate nuclear test and research
equipment, monitor radiation, and assist nuclear engineers and
physicists in research. Some also operate remote control equipment to
manipulate radioactive materials or materials to be exposed to
radioactivity.
Other science technicians collect weather information or assist
oceanographers.
Science technicians work under a wide variety of conditions. Most
work indoors, usually in laboratories, and have regular hours. Some
occasionally work irregular hours to monitor experiments that cannot be
completed during regular working hours. Production technicians often
work in 8-hour shifts around the clock. Others, such as agricultural,
forest and conservation, geological and petroleum, and environmental
science and protection technicians, perform much of their work outdoors,
sometimes in remote locations.
Some science technicians may be exposed to hazards from equipment,
chemicals, or toxic materials. Chemical technicians sometimes work with
toxic chemicals or radioactive isotopes, nuclear technicians may be
exposed to radiation, and biological technicians sometimes work with
disease-causing organisms or radioactive agents. Forensic science
technicians often are exposed to human body fluids and firearms.
However, these working conditions pose little risk, if proper safety
procedures are followed. For forensic science technicians, collecting
evidence from crime scenes can be distressing and unpleasant.
Science technicians held about 208,000 jobs in 2002. As indicated by
the following tabulation, chemical and biological technicians accounted
for over half of all jobs:
Chemical technicians
69,000
Biological technicians
48,000
Environmental science and protection technicians,
including health
28,000
Agricultural and food science technicians
20,000
Forest and conservation technicians
19,000
Geological and petroleum technicians
11,000
Forensic science technicians
8,400
Nuclear technicians
5,700
Chemical technicians held jobs in a wide range of manufacturing and
service industries, but were concentrated in chemical manufacturing,
where they held 26,000 jobs. About 17,000 worked in professional,
scientific, or technical services firms; about 17,000 biological
technicians also worked in professional, scientific, or technical
services firms. Most other biological technicians worked in
pharmaceutical and medicine manufacturing or for Federal, State, or
local governments. Significant numbers of environmental science and
protection technicians also worked for State and local governments and
professional, scientific, and technical services firms. Almost
two-thirds of forest and conservation technicians held jobs in the
Federal Government; another 20 percent worked for State governments.
Around 22 percent of agricultural and food science technicians worked
for food processing companies; most of the rest worked for scientific
research and development services firms and State governments. Over
one-fifth of all geological and petroleum technicians worked for oil and
gas extraction companies, and forensic science technicians worked
primarily for State and local governments.
There are several ways to qualify for a job as a science technician.
Many employers prefer applicants who have at least 2 years of
specialized training or an associate degree in applied science or
science-related technology. Because employers’ preferences vary,
however, some science technicians have a bachelor’s degree in
chemistry, biology, or forensic science, or have taken several science
and math courses at 4-year colleges.
Many technical and community colleges offer associate degrees in a
specific technology or a more general education in science and
mathematics. A number of 2-year associate degree programs are designed
to provide easy transfer to a 4-year college or university, if desired.
Technical institutes usually offer technician training, but provide less
theory and general education than do technical or community colleges.
The length of programs at technical institutes varies, although 1-year
certificate programs and 2-year associate degree programs are common.
More than 20 colleges or universities offer a bachelor’s degree
program in forensic science; more than 10 additional schools offer a
bachelor’s of science in chemistry, biochemistry, or genetic
engineering with an emphasis on forensic science; a few additional
schools offer a bachelor’s of science degree with an emphasis in a
specialty area, such as criminalistics, pathology, jurisprudence,
odontology, toxicology, or forensic accounting. In contrast to some
other science technician positions that require only a 2-year degree, a
4-year degree in forensics science is usually necessary to work in the
field. Knowledge and understanding of legal procedures also can be
helpful. Forestry and conservation technicians can choose from more than
20 associate degree programs in forest technology accredited by the
Society of American Foresters.
Most chemical process technicians have a 2-year degree, usually an
associate degree in process technology, although in some cases a high
school diploma is sufficient. They usually receive additional on-the-
job training. Entry-level workers whose college training encompasses
extensive hands-on experience with a variety of diagnostic laboratory
equipment usually require less on-the-job training. Those with a high
school diploma typically begin work as trainees under the direct
supervision of a more experienced process technician. Many with only a
high school diploma eventually earn a 2-year degree in process
technology, often paid for by their employer.
Some schools offer cooperative-education or internship programs,
allowing students the opportunity to work at a local company or other
workplace while attending classes in alternate terms. Participation in
such programs can significantly enhance a student’s employment
prospects.
Persons interested in careers as science technicians should take as
many high school science and math courses as possible. Science courses
taken beyond high school, in an associate or bachelor’s degree
program, should be laboratory oriented, with an emphasis on bench
skills. A solid background in applied basic chemistry, physics, and math
is vital. Because computers often are used in research and development
laboratories, technicians should have strong computer skills.
Communication skills also are important; technicians often are required
to report their findings both orally and in writing. Additionally,
technicians should be able to work well with others, because teamwork is
common. Organizational ability, an eye for detail, and skill in
interpreting scientific results also are important. High mechanical
aptitude, attention to detail, and analytical thinking are all important
characteristics of science technicians.
Prospective science technicians can acquire good career preparation
through 2-year formal training programs that combine the teaching of
scientific principles and theory with practical hands-on application in
a laboratory setting with up-to-date equipment. Graduates of 4-year
bachelor’s degree programs in science who have considerable experience
in laboratory-based courses, have completed internships, or have held
summer jobs in laboratories also are well qualified for science
technician positions and are preferred by some employers. However, those
with a bachelor’s degree who accept technician jobs generally cannot
find employment that uses their advanced academic education.
Technicians usually begin work as trainees in routine positions,
under the direct supervision of a scientist or a more experienced
technician. Job candidates whose training or educational background
encompasses extensive hands-on experience with a variety of laboratory
equipment, including computers and related equipment, usually require a
short period of on-the-job training. As they gain experience,
technicians take on more responsibility and carry out assignments under
only general supervision, and some eventually become supervisors.
However, technicians employed at universities often have their fortunes
tied to those of particular professors; when professors retire or leave,
these technicians face uncertain employment prospects.
Overall employment of science technicians is expected to increase
about as fast as the average for all occupations through the year 2012.
Continued growth of scientific and medical research, particularly
research related to biotechnology, as well as the development and
production of technical products, should stimulate demand for science
technicians in many industries. The increase in the number of biological
technicians will be about as fast as average, as the growing number of
agricultural and medicinal products developed using biotechnology
techniques will boost demand for these workers. Also, stronger
competition among pharmaceutical companies and an aging population are
expected to contribute to the need for innovative and improved drugs,
further spurring demand for biological technicians. Fastest employment
growth of biological technicians should occur in the pharmaceutical and
medicine manufacturing industry and in scientific research and
development services firms.
Job growth for chemical technicians is projected to grow more slowly
than average. The chemical manufacturing industry, the major employer of
chemical technicians, will experience a decline in overall employment as
companies downsize and turn to outside contractors to provide
specialized services. Job opportunities are expected to be more
plentiful in pharmaceutical and medicine manufacturing as the public
continues to demand newer and better pharmaceuticals. To meet this
demand, pharmaceutical manufacturing firms are expected to continue to
devote money to research and development, either through in-house teams,
or, increasingly, by contracting to scientific research and development
services firms, spurring employment growth of chemical technicians in
that industry. An increasing focus on quality assurance will require a
greater number of process technicians, further stimulating demand for
these workers.
Employment of environmental science and protection technicians
should grow much faster than average to help regulate waste products; to
collect air, water, and soil samples for measuring levels of pollutants;
to monitor compliance with environmental regulations; and to clean up
contaminated sites.
There will be limited demand for forest and conservation technicians
at the Federal and State government levels, leading to
slower-than-average growth, due to general downsizing and reductions in
timber harvesting on Federal lands. However, increased emphasis on
specific conservation issues, such as environmental protection, water
resources preservation, and control of exotic and invasive pests, may
provide some employment opportunities.
Employment of agricultural and food science technicians should grow
more slowly than average, mainly due to limited growth in agriculture
and the food processing industry. However, research will still be
necessary, particularly biotechnological research in the private sector,
as it becomes increasingly important to balance greater agricultural
output with protection and preservation of soil, water, and the
ecosystem. Specifically, research will be needed to combat insects and
diseases as they continue to adapt to pesticides and as soil fertility
and water quality continue to need improvement.
Jobs for forensic science technicians are expected to increase about
as fast as average. Crime scene technicians who work for State Public
Safety Departments may experience favorable employment prospects if the
number of qualified applicants remains low.
Little or no growth in employment of geological and petroleum
technicians is expected because employment in the oil and gas extraction
and mining industries, among the largest employers of geological and
petroleum technicians, is expected to decline. Job opportunities will be
more favorable in professional, scientific, and technical services
firms, as geological and petroleum technicians will be needed to consult
companies regarding environmental policy and Federal Government
mandates, such as those requiring lower sulfur emissions.
Job opportunities are expected to be best for graduates of applied
science technology programs who are well trained on equipment used in
industrial and government laboratories and production facilities. As the
instrumentation and techniques used in industrial research, development,
and production become increasingly more complex, employers are seeking
individuals with highly developed technical and communication skills.
Along with opportunities created by growth, many job openings should
arise from the need to replace technicians who retire or leave the labor
force for other reasons. During periods of economic recession, layoffs
of science technicians may occur.
