Most automotive service technicians and mechanics work in well-ventilated and well-lit repair shops. Although technicians often identify and fix automotive problems with computers, they commonly work with greasy parts and tools, sometimes in uncomfortable positions.

About 67,700 openings for automotive service technicians and mechanics are projected each year, on average, over the decade. Many of those openings are expected to result from the need to replace workers who transfer to different occupations or exit the labor force, such as to retire.

Although service technicians work on traditional mechanical systems, such as engines, transmissions, and drivebelts, they also must be familiar with a growing number of electronic systems. Braking, transmission, and steering systems, for example, are controlled primarily by computers and electronic components.

Other integrated electronic systems, such as accident-avoidance sensors, are becoming common as well. In addition, a growing number of technicians are required to work on vehicles that use electricity or alternative fuels, such as ethanol.

Service technicians use many different tools, including computerized diagnostic tools and power tools such as pneumatic wrenches, lathes, welding torches, and jacks and hoists. These tools usually are owned by their employers.

Automotive air-conditioning technicians install and repair air-conditioners and parts, such as compressors, condensers, and controls. These workers must be trained and certified in handling refrigerants.

Drivability technicians, also known as diagnostic technicians, use their extensive knowledge of engine management and fuel, electrical, ignition, and emissions systems to diagnose issues that prevent engines from performing efficiently. They often use the onboard diagnostic system of a car and electronic testing equipment such as scan tools and multimeters to find the malfunction.

Transmission technicians and rebuilders work on gear trains, couplings, hydraulic pumps, and other parts of transmissions. An extensive knowledge of computer controls and the ability to diagnose electrical and hydraulic problems are needed to work on these complex components.

Service technicians stand for most of the day, and they typically work in well-ventilated and well-lit repair shops. Although technicians often identify and fix automotive problems with computers, they commonly work with greasy parts and tools, sometimes in uncomfortable positions.

High school courses in automotive repair, electronics, computers, and mathematics provide a good background for prospective service technicians. However, high school graduates typically need further training to become fully qualified.

Completing a vocational or other postsecondary education program in automotive service technology is considered the best preparation for entry-level positions. Programs usually last 6 months to a year and provide intensive career preparation through classroom instruction and hands-on practice. Short-term certificate programs in a particular subject, such as brake maintenance or engine performance, are also available.

The U.S. Environmental Protection Agency (EPA) requires all technicians who buy or work with refrigerants to be certified in proper refrigerant handling. No formal test preparation is required, but many trade schools, unions, and employer associations offer training programs designed for the EPA exam.

Certification from the National Institute for Automotive Service Excellence (ASE) is the standard credential for service technicians. Certification demonstrates competence and usually brings higher pay. Many employers require their service technicians to become certified.

ASE certification is available in nine different automobile specialty areas: automatic transmission/transaxle, brakes, light vehicle diesel engines, electrical/electronic systems, engine performance, engine repair, heating and air-conditioning, manual drive train and axles, and suspension and steering.

To become certified, technicians must have at least 2 years of experience (or relevant schooling and 1 year of experience) and pass an exam. Technicians who achieve certification in all of the foregoing areas (light vehicle diesel engine certification is not required) may earn ASE Master Technician status.

Detail oriented. Service technicians must be aware of small details when inspecting or repairing vehicle systems, because mechanical and electronic malfunctions are often due to misalignments or other easy-to-miss causes.

Mechanical skills. Service technicians must be familiar with engine components and systems and know how they interact with each other. They often must take apart major parts for repairs and be able to put them back together properly.

Troubleshooting skills. Service technicians use diagnostic equipment on engine systems and components in order to identify and fix problems in increasingly complicated mechanical and electronic systems. They must be familiar with electronic control systems and the appropriate tools needed to fix and maintain them.

The number of vehicles in use is expected to continue rising over the projections decade, and some service technicians will be needed to maintain and repair them. Many owners are keeping their vehicles longer, which should support demand for these workers to provide the servicing that older vehicles often require.

The Occupational Employment and Wage Statistics (OEWS) program produces employment and wage estimates annually for over 800 occupations. These estimates are available for the nation as a whole, for individual states, and for metropolitan and nonmetropolitan areas. The link(s) below go to OEWS data maps for employment and wages by state and area.

CareerOneStop includes hundreds of occupational profiles with data available by state and metro area. There are links in the left-hand side menu to compare occupational employment by state and occupational wages by local area or metro area. There is also a salary info tool to search for wages by zip code.

For more details about work opportunities, contact local automobile dealers and repair shops or local offices of the state employment service. The state employment service also may have information about training programs.

The What They Do tab describes the typical duties and responsibilities of workers in the occupation, including what tools and equipment they use and how closely they are supervised. This tab also covers different types of occupational specialties.

The Work Environment tab includes the number of jobs held in the occupation and describes the workplace, the level of physical activity expected, and typical hours worked. It may also discuss the major industries that employed the occupation. This tab may also describe opportunities for part-time work, the amount and type of travel required, any safety equipment that is used, and the risk of injury that workers may face.

The How to Become One tab describes how to prepare for a job in the occupation. This tab can include information on education, training, work experience, licensing and certification, and important qualities that are required or helpful for entering or working in the occupation.

The State and Area Data tab provides links to state and area occupational data from the Occupational Employment and Wage Statistics (OEWS) program, state projections data from Projections Central, and occupational information from the Department of Labor's CareerOneStop.

The Job Outlook tab describes the factors that affect employment growth or decline in the occupation, and in some instances, describes the relationship between the number of job seekers and the number of job openings.

The More Information tab provides the Internet addresses of associations, government agencies, unions, and other organizations that can provide additional information on the occupation. This tab also includes links to relevant occupational information from the Occupational Information Network (O*NET).

The wage at which half of the workers in the occupation earned more than that amount and half earned less. Median wage data are from the BLS Occupational Employment and Wage Statistics survey. In May 2023, the median annual wage for all workers was $48,060.

N2 - This has been the third workshop around Statistical Mechanics organized in the last 6 years. The main topic consisted of spatial random processes and their connections to statistical mechanics. The common underlying theme of the subjects discussed at the meeting is the existence of a scaling limit, i.e., a continuum object that approximates the discrete one under study at sufficiently large spatial scales. The specific topics that have been discussed included two-dimensional and high-dimensional critical models, random graphs and various random geometric problems, such as random interlacements, polymers, etc. The workshop bolstered interactions between groups of researchers in these areas and led to interesting and fruitful exchanges of ideas.
