If you are clean, can read, have some math skills (pre-algebra preferred, but not required),
The biggest reason that people do not finish our apprentice program is because they can't do the math in the lessons. We require at least one year of HS algebra with a minimum grade of C to get into the program and we run a math review class before starting the first year lessons. We have found that a large percentage of those who do not have a passing grade on the test at the end of the math review class cannot maintain the required scores on the lesson tests.
There is not a lot on math on our pre-test.
