INTRODUCTION
The aim of this paper is to develop and test a theoretical and conceptual framework for an alternative approach to evaluation of public housing programmes in Nigeria. It seeks to address limitations of existing approaches where one theory or discipline has the upper hand in evaluating public housing programmes. This paper proposes a broad-based framework for assessing relationships between input, output and outcomes of public housing programmes through a realistic approach to evaluation based on objective-oriented theory, theory-driven evaluation paradigm and conceptual issues. This approach allows for the use of logical framework to explain the complex connections between underlying programme theory and outcomes. The distinct features of this alternative evaluation approach include: an open-ended evaluation approach; housing providers and residents participation; broad-based and a multi-faceted data gathering approaches and analysis in distinguishing the outcome of different housing delivery strategies in public housing programmes.
