To develop a systematic evaluation system, a planning team should initially identify the needs of target groups. Needs which can be met are defined as behavioral objectives. Once the behavioral objectives and those specific elements essential to achieving them (enabling objectives) are defined and classified, performance measures can be constructed. These measures provide feedback into the system for evaluation of progress toward specific behavioral outcomes. Results of this feedback will determine whether modification and recycling of the system are necessary to achieve the desired behavioral outcomes. A flow chart representing the major stages of evaluation systems development is included. A related document is EA 002 477.
