While most infrastructure discussions consider transportation, energy, and more, they too often ignore K-12 public schools, which welcome more than 50 million children and adults every day. K-12 public schools represent the nation's second-largest infrastructure sector. Schools are economic drivers, as well-prepared students will earn $1 million more over their lifetimes than their less educated peers. The condition of school buildings provides a crucial foundation for classroom learning that affects students and the American economy. Congress should dedicate most school infrastructure funds to address all schools in poor condition. This funding would address critical building systems that affect basic building operations, such as roofing, insulation, and plumbing, as well as heating, ventilation, and air conditioning. This priority alone will cost a significant amount of money: Reports estimate that bringing all U.S. schools into good overall condition will cost approximately $200 billion.
