Science technicians use the principles and theories of science and mathematics to solve problems in research and development and to investigate, invent, and help improve products. Their jobs are more practically oriented than those of scientists.
In recent years, laboratory instrumentation and procedures have become more complex, changing the work of science technicians in research and development. The increasing use of robotics to perform many routine tasks formerly done by technicians has freed technicians to operate other, more sophisticated laboratory equipment. Science technicians make extensive use of computers, computer-interfaced equipment, robotics, and high-technology industrial applications such as biological engineering.
Technicians set up, operate, and maintain laboratory instruments, monitor experiments, calculate and record results, and often develop conclusions. Those who work in production test products for proper proportions of ingredients or for strength and durability.
Agricultural technicians work with agricultural scientists in food and fiber 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.
Biological technicians work with biologists, studying living organisms. They may assist scientists who conduct medical research, helping to find a cure for cancer or AIDS, for example, or they may help conduct pharmaceutical research. Biological technicians also analyze organic substances such as blood, food, and drugs; some examine evidence in criminal investigations. 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 these techniques in product development.
Chemical technicians work with chemists and chemical engineers, developing and using chemicals and related products and equipment. Most do research and development, testing, or other laboratory work. For example, they might test packaging for design, materials, and environmental acceptability; assemble and operate new equipment to develop new products; monitor product quality; or develop new production techniques. Some chemical technicians collect and analyze samples of air and water to monitor pollution levels. Those who focus on basic research might produce compounds through complex organic synthesis.
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.
Petroleum technicians measure and record physical and geologic conditions in oil or gas wells using instruments lowered into wells or by analysis of the mud from wells. In oil and gas exploration, they collect and examine geological data or test geological samples to determine petroleum and mineral content. Some petroleum technicians, called scouts, collect information about oil and gas well drilling operations, geological and geophysical prospecting, and land or lease contracts.
Other science technicians collect weather information or assist oceanographers.
Employers seek well trained individuals with good laboratory skills for science technician positions.
Science technicians work under a wide variety of conditions. Many work indoors, usually in laboratories, and have regular hours. Some occasionally work irregular hours to monitor experiments that can't be completed during regular working hours. Others, such as agricultural and petroleum technicians, perform much of their work outdoors, sometimes in remote locations, and some may be exposed to hazardous conditions. Chemical technicians sometimes work with toxic chemicals; nuclear technicians may be exposed to radiation; and biological technicians sometimes work with disease-causing organisms or radioactive agents. However, there is little risk if proper safety procedures are followed.
Science technicians held about 244,000 jobs in 1992. Nearly 40 percent worked in manufacturing, mostly in the chemical industry, but also in the petroleum refining and food processing industries. Almost 20 percent worked in colleges and universities and another 12 percent worked in research and testing services.
In 1992, the Federal Government employed about 19,000 science technicians, mostly in the Departments of Defense, Agriculture, Interior, and Commerce.
There are several ways to qualify for a job as a science technician. Most employers prefer applicants who have at least 2 years of specialized training. Many junior 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 generally offer technician training but provide less theory and general education than junior or community colleges. The length of programs at technical institutes varies, although 2-year associate degree programs are common. Some of these schools offer cooperative-education programs, allowing students the opportunity to work at a local company while attending classes in alternate terms. Many science technicians have a bachelor's degree in science or mathematics, or have had science and math courses in 4-year colleges. Some people with bachelor's degrees in a physical or life science become science technicians because they can't find or don't want a job as a scientist or because employers couldn't find properly trained technicians with less education. In some cases, they may be able to move into jobs as scientists, managers, or technical sales workers.
Some companies offer formal or on-the-job training for science technicians. Technicians also may qualify for their jobs with some types of Armed Forces training.
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's or bachelor's program, should be laboratory oriented, with an emphasis on bench skills. Because computers and computer-interfaced equipment are often used in research and development laboratories, technicians should have strong computer skills. Communication skills are important, and technicians should be able to work well with others since technicians often are part of a team.
Technicians usually begin work as trainees in routine positions under the direct supervision of a scientist or 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 much shorter period of on-the-job training. As they gain experience, they take on more responsibility and carry out assignments under only general supervision. Some eventually become supervisors.
Employment of science technicians is expected to increase about as fast as the average for all occupations through the year 2005. Continued growth of scientific research and development and the production of technical products should spur demand for all science technicians. Advances in biotechnology will increase the need for biological technicians in particular. However, growth of job openings will be moderated somewhat by an expected slowdown in overall employment growth in the chemical industry, where many chemical technicians are employed.
Nevertheless, job opportunities are expected to be very good for graduates of science technician training programs who are well-trained on the equipment currently in use in industrial and government laboratories. As the instrumentation and techniques used in industrial research and development laboratories becomes more complex, employers are seeking well trained individuals with highly developed technical and communication skills.
Despite the projected growth, most job openings will arise from the need to replace technicians who retire or leave the labor force for other reasons.
Median annual earnings of science technicians were about $25,300 in 1992; the middle 50 percent earned between $18,700 and $33,400. Ten percent earned less than $14,400, and 10 percent earned over $42,400. At all income levels, chemical technicians earned significantly more than biological technicians.
In the Federal Government in 1993, science technicians could start at $14,600, $16,390, or $18,340, depending on their education and experience. The average annual salary for biological science technicians in nonsupervisory, supervisory, and managerial positions employed by the Federal Government in 1993 was $24,828; for mathematical technicians, $29,239; for physical science technicians, $31,484; for geodetic technicians, $37,282; for hydrologic technicians, $28,635; and for meteorologic technicians, $36,408.
Other technicians who apply scientific principles at a level usually taught in 2-year associate degree programs include engineering technicians, broadcast technicians, drafters, and health technologists and technicians. Some of the work of agricultural and biological technicians is related to that in agriculture and forestry occupations.
