Science of reading laws are state statutes that require public schools to teach early reading through explicit, systematic phonics instruction grounded in cognitive research, to screen every young child for reading difficulties, and to intervene quickly when a student falls behind. More than 40 states have passed some version of these laws, and while the details vary, the core requirements are consistent: a specific kind of classroom instruction, universal screening in the early grades, individual plans for struggling readers, retrained teachers, and in many states, mandatory retention of third-graders who cannot read at grade level.1National Center for Education Statistics.

What Schools Must Teach
At the core of every science of reading statute is a set of instructional components drawn from the National Reading Panel’s 2000 report. State laws require elementary reading curricula to address all five:2National Institute of Child Health and Human Development. Report of the National Reading Panel – Teaching Children to Read
- Phonemic awareness, the ability to hear and manipulate individual sounds in spoken words.
- Phonics, the direct relationship between letters and sounds, taught in a systematic sequence so students decode unfamiliar words rather than guess at them.
- Fluency, the speed, accuracy, and expression with which a student reads connected text.
- Vocabulary, the bank of words a student knows and understands.
- Comprehension, the strategies readers use to understand and think critically about text.
Statutes typically require this instruction to be both explicit and systematic. Explicit means the teacher directly explains and models a concept before students practice it. Systematic means skills are introduced in a planned, building-block order rather than whenever they happen to come up in a story. Those two words show up in nearly every state’s statutory language.
Bans on Three-Cueing
At least 18 states have formally banned the three-cueing system from publicly funded classrooms. Three-cueing taught children to guess at unfamiliar words by looking at pictures, thinking about what word would make sense in the sentence, or checking the first letter against their guess. Research consistently showed the method trained children to skip past the letters on the page, which is the opposite of what skilled readers do. States that have banned cueing require districts to strip the strategy from curricula and instructional materials entirely.
Approved Curriculum Lists
Many states maintain approved lists of reading curricula that districts may adopt. State education departments review the programs, and ones that rely on discredited methods are excluded. In these states, districts cannot purchase reading materials with public funds unless the program appears on the approved list. Balanced-literacy and whole-language programs are effectively locked out of these markets.
Universal Screening in the Early Grades
Science of reading laws take a prevention-first approach. Rather than waiting for a child to fail, most states require schools to screen every student in kindergarten through third grade at least three times a year: at the start, in the middle, and near the end. The assessments are brief, often only a few minutes per student, and they measure foundational skills that predict later reading success, including rapid automatized naming and phonological processing.
Dyslexia identification is a major driver of these screening requirements. More than 40 states now mandate some form of dyslexia screening in elementary schools. Dyslexia affects roughly one in five students, and early screening catches those children in kindergarten or first grade, when intervention is most effective.
What Parents Receive
State laws typically require schools to share screening results with parents within a set number of days, often 15 to 30 days after the assessment is scored. The notice must include the student’s results, what those results mean, and what the school plans to do next.
What Happens If a Child Falls Behind
When a screening identifies a student as reading below grade level, the law triggers a mandatory response. The school cannot simply note the result and move on.
Individual Reading Plans
Districts must develop an individual reading plan for every student who falls below the proficiency benchmark. The plan identifies the specific skills the student is missing, sets measurable goals, and describes the instructional strategies the school will use. It must target the exact deficits the screener revealed, whether that is letter-sound correspondence, blending, fluency, or comprehension.
Parents receive a copy of the plan and, in most states, must be consulted during its development. Schools are required to provide regular progress updates, often at the same intervals as the screening schedule, and must adjust the plan if a child is not making adequate progress.
Intensive Intervention
Flagged students receive additional instructional time dedicated to reading beyond the standard literacy block. The specifics vary by state, but the common thread is a meaningful increase in minutes spent on structured reading practice, frequently in small groups of three to five students. Some states specify that total daily reading instruction for struggling students must reach 90 minutes or more. Intervention sessions must use the same evidence-based methods required for general classroom instruction. A school cannot teach phonics in the morning block and then switch to a guessing-based program during intervention time. Intervention continues until the student demonstrates proficiency on subsequent screenings.
Summer Reading Camps
Many states require districts to offer summer reading camps for students who do not meet grade-level benchmarks by the end of the school year. These programs provide intensive daily instruction over several weeks. In states with retention mandates, successful completion of a summer camp can also provide an alternative pathway to promotion.
Third-Grade Retention
The most consequential provision in many of these laws is mandatory retention. If a student cannot demonstrate reading proficiency by the end of third grade, the student is held back. At least 13 states and the District of Columbia have some form of this requirement. The reasoning is that third grade marks the transition from learning to read to reading to learn, and promoting a student who cannot read into a reading-dependent curriculum compounds the problem.
Research on whether retention actually helps is mixed. Some studies show short-term gains that fade within a few years; others find lasting harm from stigma and social disruption. Supporters argue the alternative, social promotion, moves the problem forward without solving it.
Good Cause Exemptions
Every state with a retention mandate includes exemptions. The exact list varies, but the most common categories are:
- Students with disabilities whose individualized education programs already address reading deficits, or who use alternate assessments.
- English learners who have been in an English language program for fewer than two years.
- Students who have already been retained in an earlier grade and have received ongoing intervention.
- Students who demonstrate grade-level proficiency on a state-approved alternative assessment.
- Students who attend and pass a summer reading camp.
Parents have the right to appeal a retention decision. The process typically involves a review by the school principal or district superintendent, and the parent may present evidence that promotion is in the child’s best interest. A retention decision is not final until the appeals window closes.
Teacher Training Requirements
Mandating a type of instruction means little if teachers were never trained to deliver it. Most practicing teachers learned to teach reading through balanced-literacy coursework, so these laws created an enormous retraining obligation. States address it through three channels.
Professional Development for Current Teachers
The most widely adopted program is Language Essentials for Teachers of Reading and Spelling, known as LETRS. Roughly half of all states have contracted with the publisher to provide statewide training. LETRS takes approximately 160 hours to complete over two years and covers the cognitive science of reading, the structure of the English language, and techniques for delivering phonics-based instruction. Some states pay for the training; others require districts to cover it. Teachers who fail to complete mandated training in the required timeframe can face consequences ranging from loss of bonus eligibility to license non-renewal.
Certification Exams for New Teachers
A growing number of states require new teachers to pass a standalone literacy exam before earning certification. These exams test knowledge of phonemic awareness, syllable types, morphology, and instructional strategies, going well beyond the general-knowledge content tests that were previously sufficient.
University Preparation Programs
The laws reach into higher education as well. States increasingly require university teacher preparation programs to align their reading coursework with evidence-based standards such as the Knowledge and Practice Standards published by the International Dyslexia Association. Programs that fail to demonstrate alignment risk losing state accreditation, which would make their graduates ineligible for teaching licenses.
How States Enforce the Laws
State education departments enforce these statutes through reporting requirements, curriculum reviews, and public data disclosure. Districts typically must submit literacy plans detailing their chosen curricula, screening tools, and intervention protocols. The state may reject plans that rely on prohibited methods.
Public reporting of school-level and district-level literacy data drives further accountability. Parents and community members can see how their local schools compare. Districts that consistently fail to meet benchmarks may face escalating consequences, from state audits and mandatory corrective action plans to the withholding of certain state funds. In the most extreme cases, some state laws authorize the state to intervene directly in a district’s instructional decisions.
What Parents Can Do With These Rights
The screening notifications, reading plan consultations, and progress reports create a paper trail parents can use. If a district is not providing the interventions outlined in a child’s plan, parents have grounds to escalate through the district’s internal complaint process, and ultimately to the state education department if the district is out of compliance with state law.
If you believe a school is still using banned methods, filing a complaint with the state education department is the most direct route, and some states have formal complaint processes specifically for instructional non-compliance. Parents who want to supplement school instruction can hire a private tutor trained in structured literacy, though that typically runs $75 to $185 per hour depending on region and credentials.
What the Results Look Like So Far
The strongest evidence comes from Mississippi, which passed its comprehensive literacy reform in 2013 and is roughly a decade ahead of most states on implementation. Mississippi’s fourth-graders went from ranking 49th nationally to tied for 8th on the 2024 NAEP reading assessment.1National Center for Education Statistics. Explore Results for the 2024 NAEP Reading Assessment The gains are real, but they come with caveats. Mississippi’s eighth-grade reading scores did not show the same improvement, raising questions about whether early gains hold as students move through upper grades. And nationally, fourth-grade reading scores continued to decline even as more states adopted these laws, though most of those laws are too new to have produced measurable results yet.
The biggest open question is implementation quality. A law can mandate phonics, but the actual instruction depends on how well teachers were trained, how faithfully schools follow the approved curriculum, and whether intervention services have the staffing and daily minutes the law assumes. Early adopter states have found that passing the statute is the straightforward part. Making every classroom deliver what the statute promised is harder.
