Article: You will need a high school diploma in order to get most skilled jobs. If you're in high school and you don't think it is helping you move toward your goal, remember that when you are a diesel mechanic you will be using a variety of skills learned in school, such as math and physics.  If you know you want to be a mechanic before entering high school, consider going to a technical high school in your area. The programs at these schools often give students who want to go into a trade a good head start in their careers.  If you do not have a high school diploma and are too old to go to high school, don't despair. You can take classes and get a high school equivalency degree at any age. Some high schools offer general shop classes that will allow you to get comfortable using tools and machinery. In some specialized technical schools, you may even be able to take auto mechanic, electrical, or machining classes. Even basic classes in science and math can help you in your goal of becoming a diesel mechanic. For example, science classes in physics and chemistry can help you understand how engines work. Even if your high school doesn't have a technical program, that doesn't mean you can't learn on your own. Many diesel mechanics start out working on smaller, simpler engines. Consider having an ongoing engine project at home that allows you to do some hands-on learning. Practice working on auto, motorcycle, or small machine engines, such as those in lawn mowers.  Understanding how these simpler and smaller engines work will help you work your way up towards being a diesel mechanic. Diesel mechanics need to have an understanding of electrical systems, in addition to engines. Get some practice with electrical systems as well if you can. Go to your local department of motor vehicles or their website and look up the requirements. In most cases you will need to be 18, have a valid regular driver's license, pass a written test, and take a driving test. This license is required when operating large vehicles. As a diesel mechanic, you will need to be able to drive vehicles that are in need of repair, have been repaired, and need to be tested and adjusted while being fixed.
