ROC/Ps are designed to supplement the vocational training capacity of schools throughout California. Their strength derives from their ability to transcend jurisdictional boundaries and thereby increase the range of training opportunities for students in multiple school districts. The link between training and employment is emphasized and becomes a standard by which individual program components are evaluated. Advantages to these programs include student access to market-relevant vocational instruction, teacher access to supplemental income, ability of schools to expand and improve vocational education curricula, and greater contact of school districts with the local business community. Apparent problems with these programs are magnitude, bureaucracy, costs, and uneven participation.
