There are two approaches of evaluating a program. Qualitative methods of evaluation determine the meaning and experience of the program for the people involved; and interprets the effects that may be obs1:rved. Quanlilalivc methods measure and 'score' changes occurring as a result of the program. Such measurements are systematica lly made using pm-selec ted inslrurneots to detect cxpecti;:d changes. An evaluation may look into three <spects of a program, namely: its processes, impact and outcomes. Process evaluation measnres tl1e acrivitias of rhe program, its quality and who it is reaching out.
