Educational administration is undergoing a structural reconfiguration driven by the tension between localized autonomy and system-wide coherence. While decentralized administration and school-based management are widely adopted to enhance responsiveness, they often generate operational fragmentation and capacity strains that isolated school-level reforms cannot resolve. This conceptual paper addresses this theoretical fragmentation by developing an integrative framework that positions five interdependent constructs—decentralized administration, shared services and collaborative arrangements, technology-enabled support, education staffing models, and system-level leadership—as mutually constitutive layers of modern educational governance. Drawing exclusively on a curated corpus of contemporary literature, we argue that effective administration emerges not through independent policy levers but through the deliberate alignment of these components. The proposed framework posits that decentralization triggers the need for shared services to pool resources, which are operationalized through strategic staffing redistribution and enabled by digital infrastructure that reduces information asymmetry. System-level leadership serves as the critical coordinating mechanism that aligns these structural, human, and technological layers to craft coherence and build adaptive capacity. Five analytical propositions are formulated to specify the directional, mediating, and moderating relationships among these constructs, explicitly identifying boundary conditions such as governance design, digital readiness, and accountability regimes. The study concludes with implications for theory, policy, and practice, advocating for bundled reforms that integrate governance autonomy with collaborative infrastructure, digital interoperability, and equitable workforce redesign. This integrative model provides a heuristic for researchers and leaders to diagnose systemic misalignments and design administrative architectures that sustain both efficiency and equity in decentralized contexts.
