The suitability of computer-based instruction (CBI) for workers with limited education was evaluated in an Hispanic orchard workforce that reported little computer experience and 5.6 mean years of formal education. Ladder safety training was completed by employees who rated the training highly (effect size [d_gain] = 5.68), and their knowledge of ladder safety improved (d_gain = 1.45). There was a significant increase (p < 0.01) in safe work practices immediately after training (d_gain = 0.70), at 40 days post training (d_gain = 0.87) and at 60 days (d_gain = 1.40), indicating durability. As in mainstream populations, reaction or affective ratings correlated well with utility ratings, but not with behavior change. This demonstrates that an agricultural workforce with limited formal education can learn job safety from CBI and translate the knowledge to work practice changes, and those changes are durable.

Mexican immigrants working at a wholesale nursery were involved in developing user instructions for a computer-based instruction system. Sixty-one Latinos with 0 to 16 years of education completed user instructions delivered on the computer, and all but 3 completed training content about the nursery. Based on objective criteria, program use was rated as "somewhat easy" to "easy" for most participants with more than 3 years of education, whereas 50% of those with 0 to 2 years of education completed content with "difficulty" or "struggled. " Participants who completed the computer-based posttest (n = 22) had a mean performance of 96%, which was significantly better than the performance of 87% (n = 18) on an oral pretest (p = .003, d = 1.02). Thus, computer-based instruction can effectively train immigrant Latinos who have very limited formal education.
