Detailed Guide for

Green Leaf   Biological Technicians in California

May also be called: Biological Science Laboratory Technicians; Environmental Technicians; Resource Biologists; Wildlife Biology Technicians

What Would I Do?

Biological Technicians* work with biologists studying living organisms. They set up, operate, and maintain laboratory instruments; monitor experiments; make observations; calculate and record results; and often develop conclusions. Many assist scientists who conduct medical research-helping to find a cure for cancer or AIDS, for example. Those who work for pharmaceutical companies help develop and manufacture medicines, while those working in the field of microbiology generally work as laboratory assistants, studying living organisms and infectious agents. They also analyze organic substances, such as blood, food, and drugs. Biological Technicians working in biotechnology apply knowledge and techniques gained from basic research, including gene splicing and recombinant DNA, and apply them to product development.

Tools and Technology

Biological Technicians normally use such tools as inverted microscopes, manual or electronic hematology differential cell counters, microplate readers, electrophoresis boxes, and automated liquid handling systems, among others. They should also be proficient in analytical, database user interface and query, graphics or photo imaging, spreadsheet, and word processing software.

Green Economy

Within the green economy, Biological Technicians often work as part of a natural resource management team. They can make field observations of natural resource conditions, assist in preparation of draft reports, plans, and guidelines, and provide logistical support and area orientation for contract and cooperating scientists. Biological Technicians may also provide assistance to students, student conservation assistants, and volunteers involved in resource management projects and field research. With additional short-term training in plant propagation and tissue culture, Biological Technicians also aid in the production of biofuels, such as ethanol and biodiesel.

Working Conditions

Biological 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 Biological Technicians often work in eight-hour shifts around the clock. Other Biological Technicians, such as those who work in State or national parks, fisheries, and other natural resource conservation areas, may perform much of their work outdoors, sometimes in remote locations.

Biological Technicians sometimes work with carcinogenic or radioactive agents or disease-causing organisms. However, these working conditions pose little risk if proper safety procedures are followed.

Biological Technicians are generally not unionized, except when employed by federal, State, or local government.

Will This Job Fit Me?

People interested in becoming Biological Technicians should enjoy work activities that include practical, hands-on problems and solutions. They should also like to work with ideas, search for facts, and figure out problems mentally.

What Wages and Benefits Can I Expect?


The median wage in 2021 for Biological Technicians in California was $53,657 annually, or $25.80 hourly. The median is the point at which half of the workers earn more and half earn less.

How Do I Qualify?

Education, Training, and Other Requirements

Prospective Biological Technicians should have at least an associate degree or a certificate in applied science or science-related technology. Many technical and community colleges offer programs in a specific technology or more general education in science and mathematics. However, some employers of Biological Technicians prefer applicants who hold a bachelor's degree in one of the biological sciences. A number of associate degree programs are designed to provide easy transfer to bachelor’s degree programs at colleges or universities.


Those interested in a career as a Biological Technician may benefit from specialized training under the direct supervision of a more experienced technician. This hands-on experience in a laboratory or field setting, combined with one's classroom learning of scientific principles and theory, usually will produce the well-rounded applicant for which many employers of Biological Technicians are looking.

Early Career Planning

High school students interested in careers as Biological Technicians should take as many 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 chemistry, physics, and math is vital.

Continuing Education

While continuing education is not mandatory to become or stay employed as a Biological Technician, many in the field may find it worthwhile to keep updated on the ever-changing nature of scientific theories and laboratory techniques.

Where Can I Find Training?
