General Educational Development (GED)

GED embraces those aspects of formal and informal education that contribute to the worker's:

(a) reasoning development and ability to follow instructions

(b) acquisition of "tool" knowledge such as language and mathematical skills. 

Experience and/or self-study can develop GED.

There are three categories of GED: Reasoning, Math, and Language.
