Maine
Maine's public school system is distinguished by its extreme geographic dispersion and aging demographic — it has the oldest median-age population of any US state, which drives a declining K-12 enrollment trend that threatens the viability of small rural schools. The state has 246 school administrative units, many serving tiny populations across forested, coastal, and island communities. Maine piloted a proficiency-based graduation model, which became state law in 2012 before being made optional in 2018 after pushback from districts. Per-pupil spending is above average, and the state's small class sizes and locally engaged communities produce academic outcomes that exceed what demographic benchmarks would predict. The Maine Educational Assessment (MEA) is the state's primary accountability instrument.
