The school enrolls 243 students and has an 11:1 student–teacher ratio, offering families a small-school setting with relatively favorable staffing levels.
Loudon Elementary’s overall performance is improving. Its ranking rose from 180th of 234 schools in 2023–24 to 133rd of 230 schools in 2025–26, while its percentile increased from 23rd to 42nd. Mathematics proficiency reached 48% in 2025–26, which was higher than both the district’s 41% and New Hampshire’s 44%. Reading proficiency was 53%, matching the district and coming close to the state’s 55%. Third grade was especially strong, with 65% proficiency in math and 63% in reading, both above district and state results. Fourth-grade math and reading results were also better than district averages.
The main concerns are fifth grade and science. Fifth-grade proficiency was 26% in math, 41% in reading, and 21% in science, below both district and state results in every reported subject. Overall science proficiency was just 21%, compared with 29% in the district and 38% statewide, and science results declined from the prior year while math and reading improved. For families, the key takeaway is that Loudon Elementary shows positive momentum, particularly in earlier grades and mathematics, but the school should continue focusing on fifth-grade preparation and science instruction. The school’s 22.22% free- or reduced-price lunch participation represents approximately 54 students based on current enrollment. The Merrimack Valley School District is ranked at the 32nd percentile statewide, while Loudon Elementary ranks at the 42nd percentile.
