QUOTES

Research finds that consolidation or merging of schools tends to produce small or mixed academic effects, some cost savings for very small systems, and significant community and equity impacts that planners often underestimate. Outcomes depend heavily on local context, school size before and after consolidation, and what students are “traded up” or “down” to in terms of school quality. link

 

 

Reviews of consolidation research indicate economies of scale in operating costs, particularly when very small districts (for example, under 300–900 students) combine, with operating spending per pupil reduced by roughly 20 percent or more in some estimates. However, consolidation also brings large one‑time and capital adjustment costs (new facilities, transportation, administration), so long‑term net savings are smaller and often minimal for already mid‑size or large systems. link

 

 

Studies of closures and mergers show that they disproportionately affect disadvantaged, low‑income, and minority communities, often accelerating population loss, reducing local property values, and weakening the connection between schools and communities in rural areas. Urban research links school mergers and closures to increased nonviolent crime near merged schools and to cycles of disinvestment and gentrification pressures in predominantly Black neighborhoods. link
