The Unfinished Work of Professionalizing Reading Education

The United States does not suffer from a shortage of scientific knowledge about reading development, reading difficulties, or effective instruction. More than six decades of interdisciplinary research(opens in a new window) have produced a robust and increasingly convergent understanding of how reading proficiency develops and how it can be improved. Yet reading outcomes remain alarmingly low.

This paradox points to a clear conclusion: the primary obstacle is no longer a gap in scientific discovery. It is the failure to institutionalize that knowledge within the systems responsible for preparing and supporting educators and educational leaders.

Central argument

The reading crisis is not only an instructional, curriculum, or policy problem. It is fundamentally a professionalization problem. Until education establishes a universally shared knowledge base, a common professional language, consistent preparation standards, and enforceable accountability mechanisms, significant variability in professional knowledge, instructional practice, and student outcomes will persist.

Unlike mature professions — such as medicine, engineering, nursing, aviation, and speech-language pathology — education has not built the guardrails that ensure scientific knowledge is translated into practice at scale. Professionalization is the missing link.

Few areas of education have benefited from a more extensive scientific knowledge base than reading. Beginning in the 1960s and accelerating across subsequent decades, researchers identified the linguistic, cognitive, developmental, and neurobiological foundations of reading acquisition. This work culminated in landmark interdisciplinary efforts — including the NICHD Reading Research Program — that integrated findings across disciplines providing the basis for developing instructional programs and assessment systems as well as the means of implementing them.

Alongside the science of reading, advances in the science of learning, the science of instruction, and implementation science have further enriched this knowledge base. Together, four interlocking bodies of evidence define what the field now knows:

The science of reading

Decades of research have established core principles about how reading proficiency develops:

• Reading is not acquired naturally, as spoken language is; it must be explicitly taught.
• Reading is a language-based developmental achievement.
• Reading proficiency depends on multiple interacting components.
• Reading difficulties can be identified early — often before formal schooling begins.
• Most struggling readers can achieve proficiency with explicit, systematic, evidence-based instruction.
• Effective instruction can shift developmental trajectories and strengthen the neural systems that support reading.

The core instructional components are based on these principles.

The science of learning

The relevant evidence base extends beyond “what works.” The science of learning examines how people acquire knowledge, retain it over time, generalize it to new contexts, and recover when learning breaks down. This science informs the conditions under which instruction is most likely to succeed.

The science of instruction

The science of instruction(opens in a new window) addresses both the design of content and its delivery. Preparing teachers to engage students is only as effective as the quality of the content they engage with. Instructional materials must be carefully structured, sequenced, practiced, and monitored to produce reliable learning outcomes.

Implementation science

Implementation science(opens in a new window) is the scientific study of methods and strategies that facilitate the uptake of evidence-based practice and research into regular use by practitioners and policymakers.

The science of reading identifies the knowledge students must acquire. The science of learning explains how that knowledge is acquired, retained, and transferred. The science of instruction translates these findings into instructional practices comprised of well-designed instruction — what to teach — and effective instructional delivery — how to teach — that reliably produce learning. Professional preparation and support should therefore include mastery of all three sciences. Implementation science focuses on closing the gap between what we know and what we do (the know-do gap) by identifying and removing barriers that impede the use of proven interventions and evidence-based practices.

The central question

The question is no longer whether scientific knowledge exists. The question is why it has not become common professional practice. The answer lies in the professional structure of reading education — not in gaps in the evidence.

A profession is not defined merely by the dedication of its members. Mature professions develop the capacity to transmit, maintain, and apply scientific knowledge consistently across practitioners and institutions. They build infrastructure that makes correct practice the norm — and makes incorrect practice harder to sustain.

Across mature professions — medicine, engineering, aviation, nursing, finance, and maritime operations — a consistent pattern emerges: evidence-based knowledge is institutionalized through shared standards, coherent training, competence-based licensure, and accountability systems that protect the public. These professions do not rely on persuasion alone. They rely on systems.

Education lacks comparable professional guardrails. As a result, children experience dramatically different learning opportunities depending on their location, the quality of their teachers’ preparation, local instructional traditions, and — most critically — whether leaders and systems align with scientific evidence. This degree of variability would be unacceptable in any trusted profession. It should be unacceptable in reading education.

Mature professions typically institutionalize five pillars that collectively ensure coherence, competence, and adherence to evidence-based practice. These pillars also support enforcement mechanisms that reduce the persistence of ineffective practice.

Pillar 1: A shared knowledge base 

Trusted professions agree on foundational knowledge — even when they debate implementation details or interpret emerging findings differently. In reading education, professionals often enter practice with substantially different understandings of critical fundamentals, including:

• How reading develops across childhood
• Why reading difficulties occur
• The role of oral language — vocabulary, grammar, listening comprehension — in reading acquisition
• The role of encoding in word reading and automaticity
• The nature and identification of dyslexia and reading-related disorders
• How assessment should guide instructional decision-making
• What characteristics define effective reading instruction

When foundational constructs are not shared, professional disagreement becomes predictable and implementation unreliable. No profession can scale competence if its members do not share a core model of the phenomenon they are meant to address.

A common professional language is central to the shared knowledge base

Even among well-intentioned and well-educated professionals, shared language matters — because it determines what people actually mean when they invoke evidence and instruction. In reading education, key terms are routinely defined differently across universities, publishers, advocacy organizations, state agencies, and professional development providers. Terms such as “science of reading,” “structured literacy,” “explicit instruction,” “balanced literacy,” “dyslexia,” and “evidence-based” carry inconsistent meanings in the field.

• This creates avoidable and costly problems:
• The same term can describe entirely different constructs.
• Different terms can describe the same construct.
• Collaboration slows as professionals talk past each other.
• Implementation fidelity erodes when apparent agreement masks real disagreement.

A common professional language, which is part of the shared knowledge base, is not a stylistic preference. It is the infrastructure that makes knowledge transferable — and enforceable.

Pillar 2: Research-aligned preparation

Trusted professions align preparation to a shared knowledge base and require trainees to understand not only discipline-specific findings, but also the broader sciences of learning, instruction design, and delivery. Preparation in reading education must similarly include the content in pillar 1.

In medicine, trainees learn evidence-based practice through structured, competence-centered programs. In reading education, preparation remains highly variable. Not all preparation programs ensure mastery of essential reading knowledge and instructional competencies, including the ability to design adaptations of reading instructional programs and deliver that instruction with fidelity. This variability helps explain why evidence-based instruction in classrooms often depends more on local training and support ecosystems than on a consistent professional standard.

Pillar 3: Licensure and professional development rooted in competence

In trusted professions, licensure signals demonstrated competence and protects the public. Professional development is not optional enrichment—it is structured, ongoing learning that sustains competence and aligns practice with advancing evidence, especially the operational decisions required to translate research into consistent instruction and effective error correction.

Education has not consistently built licensure and professional development systems around competence in evidence-based reading instruction. Licensure too often reflects completion of coursework rather than demonstrated mastery of relevant knowledge and skills.

Pillar 4: Accreditation with teeth

Today, a large percent of teacher-prep programs that fail to prepare candidates effectively still receive accreditation. No other serious profession tolerates such laxity.

Pillar 5: Accountability for professional knowledge and practice quality

Trusted professions protect the public through accountability systems that address both competence defined as adherence to evidence-based standards. Accountability does not merely track outcomes — it monitors whether core professional practices are delivered competently and consistently, including fidelity to evidence-based instructional routines and delivery requirements grounded in the sciences of learning and instruction.

In education, accountability is too often inconsistent, symbolic, or diffuse. Systems frequently emphasize reporting student results without ensuring the implementation capacity, fidelity, or professional competence required to achieve those results.

Education is notoriously susceptible to pendulum swings. When evidence is treated as optional, instruction regresses. Carnine’s Substack about “stopping the pendulum” reflects a broader pattern: reading education has repeatedly moved away from evidence-supported practices only to rediscover them after costly cycles of discrediting and re-adopting.

Phonics has been adopted, abandoned, rediscovered, and marginalized again. Whole-language instruction displaced phonics; phonics later regained prominence; then it was pushed aside once more. These cycles are not evidence of a learning field. They reveal that professional systems have failed to institutionalize evidence-based practice as the default.

Understanding the pendulum

The pendulum is best understood as a symptom of incomplete professionalization. Trusted professions do not cycle between evidence-based and discredited practices, because professional guardrails restrict individual discretion and enforce standards of practice. Education often lacks those guardrails — so local preference, ideology, and “reform churn” can override evidence repeatedly.

Evidence alone does not protect the public. Trusted professions become trusted because they build systems that ensure evidence becomes practice — even amid disagreement among practitioners. Five lessons emerge from their example.

Lesson 1: Trusted professions reduce preventable harm

Trusted professions(opens in a new window) protect the public by institutionalizing evidence through guardrails and external accountability. They do not wait for voluntary compliance. History shows that during periods when evidence existed but was not uniformly applied, preventable harm occurred. The “period of preventable harm” can be defined as the gap between when evidence is established and when it becomes uniformly applied in practice.

Reading education appears to remain in such a period. Evidence-aligned practice is not universally required, consistently supported, or effectively monitored.

Lesson 2: Members adhere to a shared knowledge base

In trusted professions, members are not free to disregard core standards of care. Local discretion exists, but it operates within shared, enforceable boundaries. In education, the scientific knowledge base is not consistently treated as a governing standard. Practice therefore depends too heavily on local interpretation, leadership preferences, and curriculum adoption cycles.

Lesson 3: Noncompliance is made harder

Trusted professions do not eliminate imperfect practice — but they reduce its invisibility and its tolerance. Education often allows ineffective practice to persist precisely because professional systems do not impose meaningful consequences for departures from evidence-based standards.

Lesson 4: Local control does not override the knowledge base

Local control and evidence-aligned professionalism can coexist. The problem is not local decision-making per se; it is local decisions made without enforceable, knowledge-based constraints. Trusted professions permit variation in context, style, and application while maintaining non-negotiable core standards. Education too often treats scientific evidence as negotiable — especially when school boards, district leaders, curriculum vendors, or preparation programs prefer alternatives.

Lesson 5: Accountability is the key mechanism

Accountability in trusted professions defines who is responsible for ensuring evidence-based practice — and establishes consequences when it does not occur. In reading education, accountability must be multi-level and enforceable. It should require:

• Classroom-level competence in evidence-based instructional routines and delivery
• Leadership responsibility for coaching, monitoring, and implementation quality
• District responsibility for fidelity to evidence-based practice across schools
• State monitoring that is both supportive and corrective when achievement levels are low and evidence-aligned practice is absent

Improving reading proficiency requires more than adopting new curricula or passing legislation. It requires building professional infrastructure that reliably translates scientific knowledge into daily practice. Five policy priorities are essential.

Priority 1: Establish a common knowledge foundation

States should define the essential professional knowledge that all educators and educational leaders must possess regarding reading development, reading difficulties, assessment, and evidence-based instruction — grounded in the science of reading, the science of learning, and the science of instruction.

Priority 2: Establish a common professional language

Preparation programs, licensure systems, professional organizations, and state agencies should adopt shared terminology and operational definitions grounded in cumulative scientific evidence. Ambiguous or inconsistently defined terms undermine implementation and accountability.

Priority 3: Strengthen evidence standards

States should clearly distinguish between claims that are merely plausible and claims that are genuinely evidence-based. They should require stronger evidence standards for curriculum adoption, intervention selection, and professional development investments — and should make those standards transparent and publicly accountable.

Priority 4: Align preparation and licensure

Teacher and leadership preparation programs should be evaluated based on demonstrated mastery of scientifically validated reading knowledge and instructional competencies, including the ability to design and deliver instruction consistent with the science of learning and the science of instruction. Licensure must reflect verified competence, not mere exposure to coursework.

Priority 5: Build accountability for professional knowledge and implementation

Accountability systems should measure both student outcomes and the quality of professional preparation, professional learning, and implementation capacity across the system. This must include monitoring fidelity to evidence-based instructional practice and requiring corrective action when competence or implementation quality is absent.

The future of reading proficiency depends less on discovering new scientific principles than on institutionalizing existing knowledge within the professional systems that prepare and govern educators.

The unfinished work of professionalizing reading education is the construction of guardrails that ensure evidence is consistently taught, consistently understood, communicated through shared language, and consistently applied in practice.

This task is not primarily scientific. It is professional. The evidence is available; the professional infrastructure remains incomplete. If education is to produce stable, sustained progress rather than perpetual pendulum swings, it must develop the shared knowledge base, professional language, competence-based preparation and licensure, and enforceable accountability systems that characterize every trusted profession.

The reading crisis is, at its core, a professionalization crisis. Addressing it requires treating professional infrastructure — not only pedagogy or policy — as the urgent priority it is.
