Abstract: Performance-based, or competency-based education (CBE) is a concept for teaching which applies to all learning levels, as presented in a collection of papers written by educators who support its theory, implications, and practical application. CBE evolved from a philosophy of education that specifies behavioral objectives for which criterion levels of performance, or competency, are defined; an instructional plan aims the learner toward achieving these minimum expectancies. CBE and traditional educational systems are compared from a psychological viewpoint. Topics explored in this sourcebook for the CBE program include empathy-competence, affective behaviors, instructional techniques, curriculum design, achievement testing, and teacher certification. The special issues of communications technology, the open classroom, and urban children examine the implementation of competency-based learning in the schools. An annotated bibliography reviews research efforts in performance-based teacher education.
