Best Public Schools in Zip Code 73448

ZIP code 73448 has three schools serving prekindergarten through grade 12: Marietta Elementary School (PK–5), Marietta Middle School (6–8), and Marietta High School (9–12). Together they enroll 1,071 students, and results vary substantially by both school and subject. The clearest shared concern is math: Elementary is at the state’s 25% proficiency rate, while Middle is at 10% and High at 2%.

Each school has a different strength. Middle is the science standout, with 40% proficiency—10 points above the state and 8 points above the next-highest local school—though its ELA and math results are below state rates. Elementary leads local math at 25% and is slightly above the state in science (32% versus 30%), but its ELA rate is 18%, 8 points below the state. High leads all-grades ELA locally at 26%, matching the state, and its graduation rate is 86% versus 78% statewide. However, High has the lowest math result, at 2%; its grade-11 ELA rate is also 10 points below the grade-specific state rate.

Recent results show improvement in science but a widening math concern: the three-school average rose by 5 points in science from 2024–2025 to 2025–2026, while the math average fell by 4 points and ELA edged up by 1 point. SchoolDigger’s 2025–2026 statewide rankings are close—35th percentile for Elementary, 34th for Middle, and 33rd for High—but moved in different directions from the prior year: down 22 percentile points for Elementary, up 20 for Middle, and up 12 for High. For context, free/reduced lunch eligible rates in 2024–2025 were 87% at Elementary, 84% at Middle, and 80% at High; student–teacher ratios were 18.8, 20.0, and 16.5, respectively. These measures describe the schools but do not explain their differing results.
