Abstract: Training system software is operable on a digital computer for providing training to operator trainees of underground storage tank containing facilities. The software is capable of delivering facility specific training materials specifically applicable to an operator-trainee's designated facility. The software includes generic content component training materials for providing training applicable to a plurality of facilities including the operator trainee's designated facility. The software also includes at least two sets of regional content component training materials. Each of the at least two sets provide training applicable to at least two, but less than the plurality of facilities to which the generic content component is applicable; and at least one of the sets includes regional content material applicable to the designated facility of the operator-trainer. Additionally, the software includes at least four sets of facility specific component training materials.
