This presentation identifies one of four kinds of evaluation--impact evaluation--existing today for career education programs. Impact evaluation provides four essential sets of information: (1) all data necessary to determine if a program should be continued; (2) a determination of which alternative program achieves the greatest gains at a given cost; (3) information on the components of each program and the component mixes which are most effective in a given expenditure to achieve maximum operating efficiency; and (4) data from the above three for persons with different characteristics so a decision-maker can determine which individuals are best served by each program.
