The U-SAIL system is a practical approach to individualization of instruction in which a problem-solving process is employed to install a program in logical sequential phases. U-SAIL is a nationally validated, successfully replicated, cost-feasible system for individualization of instruction which can be implemented in a variety of settings with local educator implementors. Cost of implementation is compatible with those regularly required for staff training and curriculum product purchases. Affective data analysis has indicated that in Utah schools, where data were available, there has been a positive relationship between degree and time of implementation of the system and positive student attitudes.
