Includes abstract.Includes bibliographical references.This study investigates a naturalistic evaluation model’s ability to assess the outcomes and impact of development interventions in a rigorous manner. The study was undertaken by means of a meta-evaluation of five evaluation projects conducted by a socio-economic development consultancy situated in Cape Town.

These four criteria were conceptualised, operationalised and applied to the evaluation projects under review
