Exploring Theoretical Frameworks and Conceptual Models Related to Inclusiveness: A Systematic Literature Review

Inclusiveness has emerged as a multidimensional construct central to contemporary discourses in education, organizational studies, development policy, and social justice. This review synthesizes theoretical and empirical perspectives underpinning inclusiveness, exploring how various frameworks conceptualize equitable participation, representation and access. Drawing on foundational theories including Social Justice Theory (Rawls, Fraser), the Human Rights-Based Approach, the Capability Approach (Sen, Nussbaum), Theory of Planned Behaviour, Social Learning Theory and the Social Model of Disability—the paper situates inclusiveness within moral, structural, Educational and participatory paradigms. It further integrates models from education (Index for Inclusion, Universal Design for Learning), organizational studies (Organizational Inclusion and Inclusive Leadership Models) and development policy (Inclusive Development Frameworks) to illustrate operational pathways for inclusive practice. Comparative analysis reveals convergences around principles of equity, belonging and empowerment, while highlighting theoretical and methodological gaps, particularly in measuring intersectional and digital dimensions of inclusion. Emerging scholarship points toward integrated frameworks combining ecological, digital, and intersectional perspectives aligned with the Sustainable Development Goals (SDGs). The review concludes that inclusiveness should be re-envisioned not merely as integration into existing systems but as a transformative, systemic process that restructures institutions and power relations. It calls for context-sensitive, mixed-method approaches to theorizing and evaluating inclusiveness across education sectors and global contexts.
