Mechanics often get started by learning on the job or through apprenticeship programs that are offered by employers. However, a degree or certificate in mechanics may easily make a professional much more qualified and desirable for the job that they want to do. People who train in mechanics may find careers working in repair shops, auto and other vehicle dealerships, and even working for themselves as a business owner or independent contractor. The duties of mechanics may include diagnosing and repairing issues with various engines and vehicles, maintenance and upkeep of machines and vehicles, and writing up labor invoices and work orders depending on the services that are being performed. There is no certified licensing that is mandated by state law for these professionals, but certifications are offered through the ASE and other professional organizations that can make a mechanic appear to be better qualified and more desirable because they have the certification that their skills are the best that they can be. According to BLS the median annual wage of automotive service technicians and mechanics was $35,790 in May 2010 and may vary greatly depending on where they work, with government and dealership workers earning about $20 an hour while those who work in repair shops and parts stores will earn about $15 an hour for their skills. The growth of this particular career is going to remain steady, although slightly below the national average for the next 8-10 years.
