There are literally hundreds of truck driving schools across the country, each with different programs.  As with any business, there are good ones and there are bad ones.  But you have to know what to look for in a trucking school.
  There are essentially
three different types of truck driver training programs.  The first is a private school, the second is a public institution and the third is a training program run by a motor carrier.
