An expanded vision of evaluation is offered that accommodates the use of both descriptive information and evaluative information, and which connects evaluation in the naturalistic paradigm with evaluation in the rationalistic paradigm for making informed decisions within programs of education and development. The model of "Information Development and Evaluation" as presented herein is the conceptual structure around which vibrant cultures of information can be built within program organizations; and such organizations can then socialize reflective practitioners, promote collaborative group decisions and action, and shape themselves into learning organizations.
