A district can do nearly everything the new reading laws ask. It can adopt a science-of-reading curriculum, send its teachers to training, revise the policy, and update the strategic plan, and still watch third-grade scores sit roughly where they were. That is not evidence the science is wrong. It is evidence that the hardest part of reading reform was never the part that gets legislated.
The science of reading hasn't reached every classroom because awareness is not implementation. Knowing the research is one challenge. Changing what happens between a teacher and students every day is another. Most professional development is built to raise awareness, not to change practice, so one-off workshops rarely alter what teachers do. Closing the gap takes sustained, practice-connected professional development and coaching, not a single training.
Policy moved. Practice didn't.
By late 2025, roughly 40 states and the District of Columbia had passed early-literacy laws grounded in or referencing the science of reading.¹ That is a remarkable shift in a short time, and it has pushed a great deal of money toward training and materials. Yet visit classrooms in a district that has done all of it, and you will often find instruction that looks much as it did before.
This is the gap that should occupy a school leader, because it is the one inside your control. The research is strong. The models are clear. The laws have created the will. What has not been solved is the translation problem: how to get well-established research to change what a particular teacher does with a particular group of children on a Tuesday. That problem is not academic, and it is not about teacher motivation. It is about how schools try to change practice, and the dominant method does not work well.
Why the gap persists
Three things explain most of it.
Teacher preparation lagged for a generation.
Many teachers now in classrooms were trained in programs that presented balanced literacy as settled practice and spent little time on phonemic awareness, the structure of English spelling, or how reading develops. You cannot expect someone to teach well what they were never taught, and a half-day in-service does not backfill a degree. A large share of the workforce needs to learn content they were never given, which is a much bigger task than "rolling out" a curriculum.
Professional development was built for awareness, not change.
This is the heart of it. The default model in American schools is the event: a speaker, a slide deck, a workshop before the year starts. That format is good at introducing an idea and almost useless at changing behavior. Decades of research on professional learning, going back to the work of Bruce Joyce and Beverly Showers, found the same pattern: training that explains and even demonstrates a practice produces very little change in what teachers actually do once the door closes. The element that moved practice was coaching, watching teachers attempt the practice and giving them feedback, repeatedly, over time. Information transfers in a workshop. Behavior does not, not without practice, feedback, and time.
Individual change rarely survives an unaligned system.
Suppose a motivated teacher returns from strong training ready to teach differently. She is now working against the master schedule that gives her no protected literacy block, the leveled-text library on her shelf, the assessment calendar built for the old model, and the teacher next door doing something else entirely. One determined person can hold out for a while. A whole building changing together is a different proposition, and reading achievement is a building-level outcome. It moves when the conditions around teachers move with them, not when a few enthusiasts push uphill.
Notice that none of these is solved by buying a better program. The program is the easy part. The hard part is adult learning at scale, sustained long enough to stick, inside a system arranged to support it.
What effective science of reading professional development looks like
If the event model is the problem, the answer is not a better event. It is a different shape of professional learning.
| Shape | One-off training | Sustained, coached PD |
|---|---|---|
| Main goal | A single event, such as a workshop or speaker | Recurring contact over a year or more |
| Link to practice | Awareness of an idea | A change in classroom practice |
| Follow-up | Separate from daily teaching | Anchored in real classroom work, applied between sessions |
| Typical result | Little or none; knowledge that fades, practice largely unchanged | Coaching cycles: observe, give feedback, return; practice that shifts and holds |
The research and the experience of schools that have actually moved point to a few features in common.
It is sustained. Real change in instruction takes a year or more of recurring contact, not a day. The cadence matters more than the venue; whether sessions happen in person, in a hybrid format, or remotely is far less important than whether they keep happening and build on each other.
It is practice-connected. The learning is anchored in the real problems teachers face with real students, and teachers apply it between sessions rather than filing it away. The question is always what this looks like in your room next week, not in theory.
It includes coaching cycles. This is the component the research keeps identifying as the one that changes practice. A coach observes instruction, gives specific feedback, models where useful, and comes back to see it again. The cycle repeats. That loop, not the initial training, is where teaching actually changes.
It builds content knowledge, not just compliance. Teachers cannot deliver structured literacy they do not understand, and they cannot be coached toward a target no one has helped them learn. Strong professional learning teaches the underlying knowledge of how reading works, then supports its use.
And it is coherent across the staff. When a whole team builds the same knowledge and is supported the same way, the practice survives turnover and schedule pressure. When it lives in a few volunteers, it leaves when they do.
This is a heavier lift than booking a speaker, which is exactly why it works. It is also the logic behind sustained literacy coaching and a full-model partnership: training paired with recurring, practice-connected support rather than a one-time download.
What a school leader can do about it
The gap between adopting the science of reading and implementing it consistently is fundamentally a leadership challenge. That's good news, because leadership is one of the few variables schools can actually control.
Start by treating professional learning as a system rather than a calendar event. Too often, schools invest heavily in curriculum adoption and initial training but devote far less attention to the ongoing support teachers need to translate new learning into daily practice. The result is predictable: awareness increases, but instruction changes only in pockets.
Schools that successfully sustain literacy improvement tend to focus on three things simultaneously. First, they build teacher knowledge of how reading develops and how effective instruction works. Second, they create the organizational conditions that make implementation possible, including protected instructional time, aligned materials, clear expectations, and opportunities for collaboration. Third, they develop leaders who can monitor instruction, provide feedback, and support continuous improvement over time.
This means budgeting for a year of support, not a day of training. It means pairing professional learning with coaching. It means ensuring that classroom observations, team meetings, assessment practices, and school improvement goals all reinforce the same instructional priorities. Most importantly, it means building leadership capacity so that the work does not depend on an outside expert and can survive staff turnover, competing initiatives, and the pressures of daily school life.
School leaders should also pay attention to the right indicators at the right time. In the early stages of implementation, changes in teacher practice often tell you more than student achievement data. Are teachers using the instructional routines as intended? Are students receiving more explicit instruction? Are leaders able to identify strong practice and provide actionable feedback? These are the signals that implementation is taking hold.
None of this is fast, and any honest account says so. But schools that improve reading outcomes rarely do so because they found a shortcut. They improve because they invested in the adult-learning work, aligned the system around effective instruction, and stayed with the work long enough for it to become the way the school operates.
Frequently asked questions
Why hasn't the science of reading reached every classroom?
Because knowing the research and changing daily teaching are different problems. Many teachers were trained in older approaches, most professional development is built to raise awareness rather than change practice, and individual change rarely survives a system that isn't aligned around it. Laws and curriculum adoptions don't close that gap on their own.
Why doesn't traditional professional development change teaching?
The standard one-off workshop is good at introducing ideas and poor at changing behavior. Research on professional learning has long found that training which explains or demonstrates a practice produces little classroom change without follow-up. The component that moves practice is coaching: repeated observation and feedback over time.
What does effective science of reading professional development look like?
It is sustained over a year or more, connected to teachers' real classroom work, and built around recurring coaching cycles rather than a single event. It develops teachers' underlying knowledge of how reading works, and it is coherent across the whole staff rather than limited to a few volunteers.
What's the difference between training and coaching?
Training builds knowledge and introduces practices, usually in a session. Coaching helps teachers put those practices to work in their own classrooms through observation, feedback, and repeated cycles. Training tells teachers what to do; coaching is what helps them actually do it. Lasting change generally requires both.
How long does it take to change reading instruction in a school?
Longer than a workshop and shorter than people fear, usually measured in school years rather than weeks. Teacher practice can shift within the first year with sustained coaching; student outcomes tend to follow as that practice becomes consistent across classrooms and grades.

¹ State-legislation figures reflect reporting and policy analysis current as of late 2025 (Education Week / EdWeek Market Brief; APM Reports; the Shanker Institute's coding of state literacy laws). The finding that coaching is the professional-development component most associated with changes in classroom practice draws on the research of Bruce Joyce and Beverly Showers.
