This article discusses the effectiveness of a theoretical-based integrated learning environment (ILE) for training non-traditional learners to perform the skills required to be successful in entry-level jobs. The ILE places instruction in a real-world, workplace context with realistic settings, characters, and storylines. The multimedia interface actively engages learners. Instructional techniques include project-based and problem-based learning, "just-in-time" remediation, scaffolding, mentoring, and individualized instruction. The assessment is transparent in that it is embedded in computer-assisted tasks. This ensures consistent monitoring of learner progress and skill mastery without interrupting the learner. This study evaluates the training performance of 206 learners (86% completion rate), and tracks learners' employment or continuing education rate during a 90-day follow-up period. Results indicate that 67% of learners gained employment or continued their education, and 15% received raises or changed jobs for higher salaries. The average wage increase was $1.06 per hour. The success of the ILE validates the application of multimedia-based simulation to education.
