For years, researchers debated whether capital spending moves the needle on learning. The most comprehensive answer to date comes from national research analyzing more than 17,000 local bond measures across 29 states, presented in NCSI’s September 2025 webinar: when districts pass facility bonds, student test scores and local home values rise.
Two findings from this research matter most for practitioners. First, the category of investment matters. Spending on basic infrastructure — heating, ventilation, and air conditioning (HVAC), health and safety, plumbing, roofing — produces larger academic gains than other categories. Earlier studies that found no test-score effect from bond passage generally didn’t distinguish what the money bought; this California bond study that found no long-term benefit is a useful example of why this distinction matters. Second, effects are largest where needs are greatest: in low-income districts, districts serving more students of color, and districts with low prior capital spending.
An important distinction runs throughout this research: investment is the act of funding improvements, while conditions are what students actually experience day-to-day. Investment improves outcomes when it changes the conditions students learn in — which is why What Works and For Whom? and studies of Los Angeles, Ohio, California, and Maryland all focus on the link between what was funded and how conditions, attendance, and scores changed.
