Science of Reading Laws: New State Mandates Explained

The landscape of American education is undergoing a seismic shift. Over the last five years, a wave of legislation has swept across the country, fundamentally changing how children are taught to read. As of late 2023 and early 2024, thirty-seven states (and the District of Columbia) have passed laws or implemented policies requiring evidence-based reading instruction. This movement is not a suggestion; it is a legal mandate to align classroom practices with the “Science of Reading.”

What Is the Science of Reading?

To understand the laws, you must first understand the definition used by legislators. The Science of Reading (SoR) is not a single curriculum or a phonics program. It is a vast body of interdisciplinary research from cognitive psychology, neuroscience, and linguistics that describes how the human brain learns to read.

Most of the new state mandates rely on the “Simple View of Reading” framework. This equation states that Reading Comprehension is the product of two distinct skills:

• Decoding: The ability to recognize words and sound them out (phonics).
• Language Comprehension: The ability to understand the meaning of the words and sentences.

For decades, many schools used an approach called “Balanced Literacy.” This method often prioritized a love of reading and context clues over explicit phonics instruction. The new laws are a direct rejection of Balanced Literacy, arguing that without structured decoding skills, students cannot become fluent readers.

The "Mississippi Miracle" as a Blueprint

Almost every new state law draws inspiration from Mississippi. In 2013, Mississippi was ranked 49th in the nation for fourth-grade reading proficiency. The state passed the Literacy-Based Promotion Act, which heavily invested in SoR practices.

The results were undeniable. By 2019, Mississippi had become the only state in the nation to see significant gains on the National Assessment of Educational Progress (NAEP), moving from the bottom tier to the national average. This phenomenon, dubbed the “Mississippi Miracle,” provided the statistical proof other state legislatures needed to justify their own mandates.

Key Components of the New Mandates

While every state has slightly different regulations, the legislation generally focuses on three specific pillars: curriculum overhauls, teacher training, and the banning of discredited methods.

1. Curriculum Overhauls and Bans

States are publishing lists of approved high-quality instructional materials (HQIM) and banning others.

• New York City: While not a state law, the nation’s largest school district implemented a mandate in September 2023. Schools Chancellor David Banks required all elementary schools to adopt one of three SoR-aligned programs: Wit & Wisdom, Into Reading, or EL Education. This effectively removed Lucy Calkins’ popular Units of Study curriculum from city classrooms.
• Ohio: Governor Mike DeWine signed a budget bill requiring all schools to use curriculum aligned with the science of reading by the 2024-2025 school year.
• Colorado: The state actively reviews curriculum lists and penalizes districts that continue to use rejected programs by lowering their accreditation rating.

2. The Ban on “Three-Cueing”

This is the most controversial and aggressive part of the new laws. “Three-cueing” is a strategy often found in Balanced Literacy where students are taught to guess a word based on three cues: meaning (pictures), structure (grammar), or visual (the first letter).

SoR advocates argue this teaches children to guess rather than read. Consequently, several states have explicitly banned this instructional method in their legislation.

• Arkansas, Louisiana, and Virginia have laws that strictly prohibit the use of three-cueing in reading instruction.
• Minnesota passed the READ Act in 2023, which prohibits purchasing curricular materials that use three-cueing.

3. Mandatory Teacher Retraining

Changing the books is not enough; states are legally requiring teachers to relearn how to teach. The most common vehicle for this is LETRS (Language Essentials for Teachers of Reading and Spelling).

• North Carolina: The state is spending over $90 million to train every elementary teacher in the LETRS program.
• Utah: Teachers must complete distinct proficiency assessments in structured literacy to renew their licenses.

The Financial and Logistic Impact

The transition is expensive and labor-intensive. The cost of replacing classroom libraries and textbooks runs into the hundreds of millions nationwide.

Funding allocations are specific:

• Indiana: The state allocated $85 million specifically for the implementation of science of reading initiatives.
• Kentucky: Legislation passed in 2022 included $22 million specifically for the Read to Succeed Act to support teacher training.

There is also a significant time cost. The LETRS training course, for example, can take two years to complete and requires over 140 hours of study and practice. Teachers unions in states like Connecticut and Ohio have expressed concern over the “unfunded mandate” of time, asking for additional compensation for the hours spent training outside of school days.

Compliance and Accountability

Unlike previous educational trends that were voluntary, these mandates have teeth. States are setting up enforcement mechanisms to ensure schools comply.

• Retention Policies: Roughly 25 states now have laws that allow or require third-grade students to be held back if they do not meet reading proficiency benchmarks.
• Screening Requirements: Most SoR laws require universal screening for dyslexia and reading deficiencies. In Tennessee, schools must screen students three times a year (fall, winter, and spring) to catch struggling readers early.

The Future of Literacy Legislation

The trend shows no sign of slowing down. As of 2024, legislatures in states like California are debating their own mandates. California Assembly Bill 2222 aimed to mandate evidence-based reading instruction and ban three-cueing, though it faces stiff opposition from the California Teachers Association and proponents of local control.

The “Reading Wars” have moved from academic journals to the statehouse. The message from thirty-seven states is clear: literacy is a civil right, and the method of instruction is now a matter of law.

Frequently Asked Questions

Which states have the strictest Science of Reading laws? Mississippi, Tennessee, North Carolina, and Arkansas are widely considered to have the most comprehensive laws. They cover everything from curriculum bans (three-cueing) to funding for teacher training and retention policies for third graders.

What specific programs are being replaced? The most notable shifts are away from “Balanced Literacy” programs. Specifically, curricula associated with Heinemann Publishing, such as Fountas & Pinnell and Lucy Calkins’ Units of Study, are being dropped by districts in mandate states in favor of programs like Core Knowledge Language Arts (CKLA) or Wit & Wisdom.

Does the Science of Reading only focus on phonics? No. While phonics is a major component that was missing from previous methods, SoR laws also emphasize vocabulary, reading comprehension, and fluency. The goal is “structured literacy,” which systematically builds all these skills together.

How do these laws affect parents? Parents in these states will likely see different homework coming home. Instead of “leveled readers” (books categorized by difficulty letters A-Z), children in early grades will bring home “decodable” books that focus on specific sound patterns they learned in class. You may also see more frequent testing or screening results regarding your child’s reading level.
