A discussion of factors associated with evaluation of proposed alternative educational systems is presented in brief form. Emphasis is given to enumeration of critical characteristics serving as the basis of comparison, examination of alternative systems in terms of each characteristic, and determination based on the comparison as to whether the systems are meaningful alternatives. Six characteristics are presented as central to the comparison of proposed educational programs: (1) Learning outcomes; (2) maximizing the number of available alternative options; (3) voluntary attendance; (4) management of motivation; (5) cost effectiveness; and (6) support of and identification with program by staff and community. A brief discussion of measurement considerations pertaining to each characteristic is also included. A selected bibliography is appended. (BL)
