Why This Matters
- About 1 in 4 U.S. adults have difficulty with basic reading (National Center for Education Statistics, 2024), yet adult literacy instruction receives far less research and investment than K-12.
- Many adult educators do not hold degrees in education or credentials specific to adult literacy, and often receive minimal in-house professional development or coaching.
- Preparation and professional learning—both pre-service and in-service—directly shape the quality of instruction adults receive.
What the Evidence Shows
- Explicit, systematic decoding instruction has the strongest evidence for adult learners; guided repeated reading supports fluency.
- Vocabulary, morphology, spelling, phonological skills, and comprehension are under-researched and warrant careful, evidence-informed instruction.
- Fewer than half of adult literacy studies reported implementation fidelity, underscoring the need for training and coaching to deliver interventions as intended.
- Reading assessments normed on children are often used with adults, so candidates need assessment literacy specific to adult learners.
Program and Professional Learning Priorities
- Teach how adults learn to read, including the core reading components and how they differ from child instruction.
- Build assessment literacy for interpreting adult reading data cautiously, given the shortage of adult-normed measures.
- Provide practice-based preparation—modeling, coaching, and feedback—to support fidelity of implementation.
- Prepare educators for varied settings: adult basic education, correctional education, workplace, community, and postsecondary transition programs.
- Extend professional learning to in-service instructors, not only pre-service candidates.
What to Watch For
- Too much theory without hands-on, practice-based experience.
- Little or no training in explicit, systematic decoding instruction for adults.
- Assuming child-focused literacy methods transfer directly to adult learners.
- Overlooking the diverse contexts and goals of adult reading instruction.
Equity Focus
- Prepare educators to support multilingual learners with varied first-language literacy.
- Prepare educators to support adults with diagnosed or undiagnosed disabilities through structured instruction.
- Emphasize responsiveness to the wide range of ages, backgrounds, and goals in adult classrooms.
Key Takeaway
Effective preparation and ongoing professional learning equip adult educators to deliver explicit, evidence-based reading instruction with fidelity across the many settings adult learners attend.
