This is a Demand OccupationA Demand Occupation is defined as follows.

The hierarchy for qualification is the Regional Demand
(the occupation had a entry wage equal to or greater
than 90% of the Economic Development Region (EDR) negotiated
wage as an average of all LWIA’s in the EDR AND at
least 25 annual average job openings in the EDR);
State Wide (the occupation qualified for at least
5 of the Regional Demands and thus was added to all
ten EDR lists); Career Cluster (the occupation is
listed on at least one of the six career clusters
Illinois has identified as priority [data is available
under the career clusters on the The National
Association of State Directors of Career Technical
Education Consortium website at ]), and Regional
Request (an LWIA received approval of a request to
add an occupation code to its EDR list based on substantiative
data and information supporting a need in the region).
NOTE: Only those occupations with a Source of Regional
Demand or State Wide will be eligible for incentive

Bus and truck mechanics work on several types of vehicles with diesel engines. These include heavy equipment, and:

  • Buses
  • Trucks
  • Bulldozers

Some bus and truck mechanics maintain vehicles. They change oil, check batteries, adjust brakes, and grease parts. They also clean or replace parts. They inspect and adjust vehicles' safety and protective features and check for loose bolts.

Bus and truck mechanics repair vehicles that are not working properly. They read job orders to learn what work needs to be done on vehicles. They follow the factory guidelines for upgrading parts or tuning engines.

They sometimes use hand-held computers to determine which part of the vehicle is causing the problem. They attach computers to parts and read the gauges to identify problems. They often take engines apart to fix problems.

Bus and truck mechanics use power tools to weld exhaust systems, to grind brakes, or to hoist heavy engines. They also use hand tools such as pliers, wrenches, and screwdrivers.

Some mechanics work on all parts of busses or trucks. Mechanics may also specialize in a particular area, such as pumps, generators, brakes, or transmissions.

Mechanics keep shop machinery functioning. They maintain and repair machinery, such as pumps and compressors.
