Evaluation of the role of structured on-site training (SOST) in the Employment Training Panel's (ETP's) training program involved 10 case studies of active ETP projects with SOST, survey of 50 recently closed projects with SOST, face-to-face interviews and focus groups with key stakeholders, Delphi survey of consultants, and quantitative analysis of contract information. A review of 1,066 contracts indicated about half included SOST funding; 30.8 percent had SOST scheduled in all jobs, about 15 percent in some jobs; and presence of SOST showed no trend over time. ETP spent about $1 of $6 on SOST; and, for 680 completed contracts, about 17 percent of total training expenditures was spent on SOST. SOST added substantial value to ETP training; trainees rated SOST quality and usefulness as significantly more useful than classroom or lab study and indicated it had a greater impact on productivity than classroom or lab training; and two-thirds of managers of closed SOST projects rated SOST as equally or more effective than classroom training in meeting training goals. Six strategic issues were identified: existing training reimbursed with SOST funds; use of unstructured practices, not SOST; contract administrators focus on billing trainer hours rather than achieving competence; difficulty of reliable monitoring of SOST; SOST reimbursement unrelated to actual costs; and SOST-only projects pay more than market price for one-on-one counseling and generic classroom training.
