The Miracle Unfolding in Mississippi Schools

What It Covers

NYT reporter Sarah Mervosh examines how Mississippi climbed from 49th in U.S. education rankings to a top-10 state for fourth-grade reading, becoming the number-one state when adjusted for poverty — while national test scores have declined since 2015, particularly for the bottom 25% of students.

Key Questions Answered

• •Science of Reading mandate: Mississippi's 2013 legislation replaced informal literacy instruction with explicit, structured phonics and vocabulary teaching statewide. Rather than allowing teachers to adopt personal methods, the state approved a short list of vetted curricula and required all schools to use them, directly targeting the gap between what students were taught and grade-level expectations.
• •Literacy coach deployment: Mississippi embeds state-employed literacy coaches in the bottom 25% of schools, coaching teachers — not students — in real time. Coaches model lessons, correct errors mid-class, and spread best practices without punitive authority. Teachers report welcoming the mentorship, and this targeted investment did not dramatically raise per-student spending from its $13,500 baseline.
• •Growth-weighted accountability grading: Mississippi grades schools A through F using a formula that counts student improvement alongside absolute scores, and double-weights progress made by the bottom 25% of performers. This incentivizes schools to invest in their lowest achievers rather than focusing resources on borderline-proficient students who are easiest to push over the threshold.
• •Third-grade retention with mandatory support: Six to nine percent of Mississippi third graders are held back annually if they cannot read at grade level, but retention is paired with after-school programs and summer school. Evidence on long-term outcomes is mixed, and critics note racial and economic disparities in who gets retained, but the state frames support as non-negotiable alongside the policy.
• •Early gains erode without sustained application: Mississippi's reading and math advantages are strongest in fourth grade and weaken by eighth grade, where Massachusetts still outperforms Mississippi significantly. The state is now pursuing adolescent literacy coaches to extend the same early-grade model upward, signaling that short-term interventions without longitudinal consistency produce diminishing returns as students age.
