On a Tuesday morning in late 2024, a small team at Brooklyn Public Library's Adult Learning Center sat together to review their volunteer tutor training materials. What they found was familiar to anyone who has watched education debates unfold over the past decade: a curriculum built on assumptions about how readers learn that had quietly fallen out of step with contemporary research.
The shift that followed was not dramatic in the way of headline-grabbing reforms. There were no new testing regimes, no legislative battles, no viral moments. What happened instead was quieter and, in many ways, more instructive: a large urban library system systematically replaced its approach to adult reading instruction with methods grounded in what researchers call the "science of reading" a body of evidence about how the brain processes text that had already transformed K-12 literacy education in schools across the country.
The work, documented across internal program records and presented through the Urban Libraries Council's Innovations database, offers a concrete case study for the growing number of libraries, community organizations, and adult education providers wrestling with a central question: what does it actually take to bring evidence-based reading science into a mature, community-embedded literacy program?
What "Science of Reading" Means for Adult Learners
The phrase "science of reading" appears frequently in education policy discussions, but its application to adult learners has historically lagged behind its adoption in elementary and secondary classrooms. The research base is robust. Decades of cognitive science, linguistics, and educational psychology have mapped the five pillars of reading: phonemic awareness, phonics, fluency, vocabulary, and comprehension. Effective reading instruction, the evidence suggests, must address all five deliberately and explicitly.
In K-12 settings, this evidence sparked what observers called the "reading wars" a decades-long conflict between advocates of phonics-heavy instruction and those who favored meaning-based whole language approaches. The science-of-reading movement ultimately tilted the field toward structured, evidence-based practices. What was slower to follow was the translation of those findings into adult literacy programs, where learners arrive with different backgrounds, motivations, and accumulated habits as readers.
"Adult literacy programs recognize the diverse needs of adult learners, often integrating real-life scenarios and experiential learning that align with their daily responsibilities and experiences," notes a research overview from EBSCO's Education Research Starters series, which surveys the landscape of U.S. adult literacy initiatives. The overview describes how modern programs work across multiple literacy types prose, document, and quantitative literacy reflecting the complexity of tasks adults encounter in their daily environments.
What Brooklyn Public Library's 2024 transformation illustrates is that bringing science-based practices into this adult-specific context requires more than swapping one curriculum for another. It requires rethinking training pipelines, volunteer systems, collections, and institutional culture simultaneously.
The Challenge of Institutional Change
When BPL's Adult Literacy department began its shift in 2024, the team faced a challenge familiar to anyone who has managed large-scale program reform: the existing approach, described internally as "balanced literacy," had not failed catastrophically. It had simply become misaligned with current evidence. The cueing strategies and leveled readers that characterized balanced literacy were not harmful, exactly. They were simply no longer the best available practice.
The challenge, as the program documented it, was finding resources, templates, and examples of previous successes for departmental change specifically in the area of adult literacy. While literacy organizations had developed evidence-based reading instructional methods, an institutional shift required strategy, delegation, and ongoing education that had not been systematically compiled for the adult learning context.
This gap between available research and institutional capacity is not unique to Brooklyn. It reflects a broader pattern across American adult education, where the definition of literacy itself has evolved well beyond the simple acquisition of basic reading and writing abilities. Contemporary understanding encompasses numeracy, functional literacy, digital literacy, and the problem-solving skills necessary for individuals to function effectively in society.
The U.S. Department of Education's Division of Adult Education and Literacy frames the mission similarly: programs must help adults acquire basic skills including reading, writing, math, English language proficiency, and problem-solving to be productive workers, family members, and citizens. The scope is immense, and the institutional infrastructure to support it varies widely across states and localities.
Funding, Partnership, and the Practical Work of Change
In 2024, BPL received $50,000 from State Assemblymember Robert Carroll specifically to update curricula to center evidence-based instructional methods. That funding, while modest, became the catalyst for a more comprehensive transformation. The team conducted research, consulted outside experts, and purchased collections for staff and tutors.
The process, as the program describes it, requires continuous onboarding, hands-on mentorship, and ongoing research. This reflects one of the consistent lessons in bringing science-of-reading practices into mature programs: initial training is necessary but insufficient. The habits and assumptions that build up over years among staff, tutors, and even learners require sustained attention.
The BPL documentation identifies several key areas that required deliberate intervention during the transition:
- Partner relationships, outreach, and funding for department initiatives
- Garnering systemwide support and awareness among library administrators
- Developing professional development for explicit instruction of all five pillars of reading
- Managing staff and tutor curriculums, collections, and instructional routines
- Recognizing cueing and "balanced literacy" habits and how to replace them with effective alternatives
- Educating the public on the science of reading and learning
- Overcoming challenges and interdepartmental resistance to change
The last item resistance to change is notably candid in the program's self-assessment. "Balanced literacy" had been the professional consensus for years. Many experienced tutors and staff had built their methods around it. Asking them to unlearn those habits and adopt new routines required not just training but a kind of organizational empathy that large institutions often struggle to provide.
What Adult Learners Need From Literacy Programs
Behind the institutional mechanics of curriculum reform lies the human stakes: the adults who walk into library literacy programs are navigating complex lives, and their reading challenges touch every part of those lives. Research consistently shows that adults with low literacy face compounded disadvantages in employment, health navigation, family engagement, and civic participation.
A national survey conducted in 2022 by ALL IN: The Adult Literacy & Learning Impact Network, in partnership with FTI Consulting, reached 2,000 adults with low literacy to understand the specific barriers they face in reaching education and career goals. The findings, published as the report "Insights from Adults with Low Literacy: Breaking Barriers to Adult Literacy Access," were designed to help local programs and educators develop more effective strategies for reaching and supporting this population.
The survey's existence reflects a broader recognition that adult literacy is not simply a skills deficit to be remediated. It is intertwined with social, economic, and cultural factors that affect how adults experience learning, how they engage with institutions, and what they need from literacy programs to actually change their circumstances.
"These programs are often community-based and may include informal settings, highlighting the role of social and cultural contexts in literacy acquisition," the EBSCO overview observes. This emphasis on community context matters when thinking about what makes library-based adult literacy programs distinct. Libraries are not schools. They do not issue credentials. They operate on voluntary participation, which means that programs must compete for attention and commitment from learners who have jobs, families, transportation challenges, and often a long history of frustrating educational experiences.
The National Action Plan and the Bigger Picture
BPL's transformation did not happen in isolation. It occurred within a broader ecosystem of adult literacy initiatives that have gained momentum over the past several years, culminating in the ALL IN National Action Plan for Adult Literacy. That plan, developed in collaboration with more than 100 expert stakeholders in and beyond the education field, represents a multisector, multiyear initiative aimed at transforming adult and family literacy for millions of Americans.
The National Action Plan's scope reflects the scale of the challenge. ALL IN's own framing states that more than 54% of U.S. adults struggle with reading, writing, and digital literacy skills a figure that, if accurate, represents one of the largest ungently-addressed infrastructure gaps in American society. The network argues that by working together to increase adult literacy, there is an unprecedented opportunity to improve collective economic mobility, public health, and quality of life, and to promote greater equity for generations to come.
What makes libraries particularly relevant to this national challenge is their accessibility. Public libraries operate in nearly every community in the United States, offer services free of charge, and have long histories of serving populations that other institutions struggle to reach. They are, by design, low-barrier entry points into learning. The question for the adult literacy field has been whether libraries can move beyond informal book clubs and one-on-one tutoring toward the kind of systematic, evidence-based instruction that the science of reading recommends.
The BPL case suggests the answer is yes but with important caveats about what that work actually requires.
The Five Pillars, Applied Differently
Science-of-reading instruction in K-12 settings typically emphasizes explicit, systematic phonics instruction as the foundation for reading development. For adult learners who missed that foundation in childhood, the application looks somewhat different. Adults bring different cognitive resources, different motivations, and different histories of struggle to the learning process.
The BPL documentation describes how the team worked to integrate structured literacy approaches while adapting them for adult contexts. Instructional routines, games, and structured literacy strategies were designed to empower both tutors and students. The goal was not simply to retrofit adult learners with the phonics instruction they missed in elementary school, but to build a comprehensive approach that addressed all five pillars in ways that resonated with adult goals and experiences.
Vocabulary development, for example, takes on different dimensions for adult learners who need to navigate workplace documents, medical forms, government paperwork, and digital interfaces tasks that children learning to read are not yet confronting. Fluency practice must account for adults who may already read at a functional level in one context but struggle in others. And comprehension strategies must be taught with the complexity of adult texts in mind.
"Many programs emphasize the importance of fostering a supportive and interactive learning atmosphere that encourages consistent reading and writing practice," the EBSCO overview notes. This emphasis on atmosphere and environment is not incidental. Adults who have experienced failure in educational settings carry that experience with them. Programs that can create a sense of safety, respect, and progress tend to retain learners longer and produce better outcomes.
Why This Matters for ReadersOpinions Readers
If you are a reader who has followed the science of reading conversation primarily in the context of K-12 education, the adult literacy angle offers a useful expansion of that framework. The evidence base that has reshaped how schools teach children to read applies with equal force to the millions of adults who are still building or rebuilding their reading skills. The difference lies not in the science but in the delivery context, the learner population, and the institutional settings where learning happens.
For readers interested in community-based education, the BPL case illustrates how large institutions can manage genuine programmatic transformation without a crisis, without a complete staff replacement, and without abandoning the community relationships that give library literacy programs their distinctive character. The key ingredients, as documented, were dedicated funding, external expertise, professional development investment, and honest self-assessment about which existing practices needed to change.
For readers interested in the policy landscape, the ALL IN National Action Plan and the federal government's Division of Adult Education and Literacy represent the institutional scaffolding that can either support or constrain local innovation. The BPL experience benefited from a state-level grant; not every library has access to that kind of targeted funding. Understanding how policy translates into practical program capacity is essential for anyone who wants to see evidence-based literacy practices reach the adults who need them most.
What Replication Requires
The Brooklyn Public Library case study was recognized through the Urban Libraries Council's Innovations database, which specifically flags programs that other libraries might replicate. The recognition is well-deserved, but replication is not automatic. The BPL transformation required leadership capacity, institutional trust, funding, and a willing staff resources that vary widely across library systems.
The program's own documentation acknowledges that the transition requires continuous onboarding, mentorship, and ongoing research. This is not a one-time curriculum swap; it is an organizational commitment to sustained improvement. Libraries considering similar changes need to assess their own readiness on multiple dimensions: Do staff and volunteers understand the evidence base? Is there leadership support for the cultural shift that comes with abandoning familiar practices? Are there partnerships with external experts who can provide ongoing coaching? Is there dedicated time and funding for the professional development that sustained change requires?
The American Library Association's own adult literacy programming, documented through its Literacy for All initiative, identifies successful and replicable library literacy programs across the country. These programs share certain characteristics: strong volunteer management systems, clear learning objectives, regular assessment of learner progress, and connections to broader community resources. What BPL's science-of-reading transition adds is the dimension of evidence-based instructional practice ensuring that the methods used to teach reading are themselves grounded in the best available research.
Looking Across the Landscape
The transformation at Brooklyn Public Library is one example, not a universal model. Adult literacy in the United States operates through a patchwork of local programs, state initiatives, federal grants, and nonprofit partnerships. The quality and capacity of these programs varies enormously. Some, like BPL, have the resources and leadership to pursue ambitious reforms. Others operate on minimal budgets, serving learners with dedicated but untrained volunteers.
What the science-of-reading movement offers to all of these programs is a shared evidence base a set of principles about how reading works and how it is best taught that transcends local traditions and individual intuition. The challenge is translating that evidence into practice in diverse settings, with diverse learners, through diverse instructors. The BPL case suggests that this translation is possible, but it requires deliberate effort, adequate resources, and a willingness to change.
For readers who want to understand the current state of adult literacy in America, the picture is one of both challenge and opportunity. The challenge is immense: tens of millions of adults reading below functional levels, navigating a society that increasingly demands literacy for basic participation. The opportunity is equally real: there are proven methods that work, there are dedicated professionals and volunteers doing the work, and there is a growing national commitment reflected in the ALL IN National Action Plan and in federal policy to do better.
The question is whether the institutional will and resource allocation will match the aspiration. Brooklyn Public Library's answer, in 2024, was yes. The question now is how many other institutions will follow.
