Literacy curricula and interventions

Strategy overview

  • Building a strong foundation: Evidence-based literacy curricula and interventions help students build the skills they need to read and write at grade level. Foundational skills, like basic writing, vocabulary, and reading fluency, are often the focus of early literacy, which is typically implemented between pre-kindergarten and third grade. As students get older, the focus shifts to reading comprehension, analysis, and exposure to complex ideas.

  • Learning to read: Literacy curricula and interventions for students in grades K-3 focus on building the skills they need to read fluently and with comprehension. Reading by the end of third grade marks a critical transition point in a child’s development: literacy skills are necessary for nearly all subjects in fourth grade and later. As a result, high-intensity interventions take on particular importance in a student’s earlier years. Many literacy interventions for younger students are delivered in small groups or one-on-one settings and may also emphasize parental engagement (i.e. reading with a child at home).

  • Reading to learn: As students advance to middle and high school, reading becomes a key skill for all types of learning. Literacy curricula and interventions, therefore, focus on exposing students to more complex ideas and themes (for instance, by assigning varied text types, like biographies, poetry, and fiction) and encouraging analysis. Evidence-based writing interventions, which are particularly common for high school students, help students apply their reading and analytical skills.

  • Selecting a curriculum to fit student, school needs: Evidence-based reading curricula vary significantly in terms of scope and scale. Some are core curricula, serving as the foundation for all literacy learning throughout the school year for an entire grade; others are short-term interventions, which can be delivered either grade-wide or for a subset of students. Curricula can also be supplemented with evidence-based practices that support literacy development, like small group classes and peer tutoring.

  • Training teachers: Many evidence-based curricula and interventions include significant training before the school year for the teachers who will deliver the model. Such training allows teachers to familiarize themselves with broader subject areas (i.e. grammar) and the specific model before engaging with students. This is often supplemented by periodic professional development workshops that help teachers make class- and student-specific adaptations as the school year progresses.

  • Accelerating student learning: An increasingly common approach to supplementing a core curriculum is through high-dosage tutoring programs, which provide intensive learning for individual students or small groups. High-dosage tutoring — which has proven effective for students of all ages and across content areas — is most impactful when integrated into the standard school day and delivered to the students who are most behind their classmates in academic progress.

What evidence supports this strategy?

Proven

Meta-analyses of rigorous studies of reading curricula and interventions found statistically significant, positive effects for students of different ages, English language learners, and students with disabilities.

  • A 2020 meta-analysis measuring the impact of reading interventions on students in grades 1-3 found a significant increase for a range of reading outcomes, particularly comprehension.

  • A 2020 meta-analysis of integrated literacy and content-area instruction in grades K-5 found positive, significant effects on vocabulary and reading comprehension.

  • A 2020 meta-analysis on language comprehension interventions for students in grades K-5 found significant positive effects on reading and listening comprehension; the effects also indicated positive outcomes for English language learners.

  • A 2017 meta-analysis and research synthesis of small group reading interventions for students with reading difficulties found significant positive effects for students of all ages in areas including vocabulary, reading comprehension, and phonics; effects were largest for elementary students.

  • A 2021 research synthesis found that high-dosage tutoring dramatically improved student performance in math and literacy, with students recovering between 3-15 months of learning and advancing an average of 16 percentile points on standardized tests.

How do reading interventions and curricula impact economic mobility?

  • Improving reading outcomes: Literacy curricula and interventions focus on helping students read at and above grade level. Improved academic performance in reading, research shows, can create multiple pathways to upward mobility, including accessing college and high-quality jobs.

  • Graduating from high school and college: A vastly disproportionate share of students reading below grade level are from low-income families, attend under-resourced schools, and/or were in foster care. Research shows that students who read above grade level at various intervals (third and eighth grade) graduate high school and enroll in college at higher rates than their peers. Higher educational attainment is also closely tied to increased earnings.

Best practices in implementation

  • Prioritize curricula with a strong teacher training component: Many curricula and related interventions provide robust training for teachers to deliver the model, along with ongoing professional development, and, in some cases, a credential. Ensuring that selected curricula have sufficient training programming and materials will better position teachers to effectively deliver the model with fidelity.

  • Incorporate relevant, culturally responsive themes: Many literacy curricula and interventions offer significant opportunities to expose students to new ideas through reading and writing. When identifying particular curricula and interventions for implementation, prioritize those that offer culturally relevant materials and lessons or provide a framework through which schools and teachers can adapt lessons to do so themselves.

  • Deliver the curriculum with a high degree of fidelity: Evidence-based curricula are often designed to be delivered under specific conditions; only certain programs are particularly adaptable to a range of implementation styles. Carefully evaluate student needs and ensure the curriculum can be delivered with fidelity, including frequency (i.e. daily), length (yearlong, quarterly, etc.), and scale (individual students, small groups, classwide).

  • Align curricula selection to student, school needs and state standards: With the proliferation of evidence-based reading curricula available, school districts have the opportunity to be highly selective. Prior to evaluating curricula, conduct a needs assessment to understand what types of features a curriculum should include, such as specialized programming for students with disabilities or English Language Learners. Curricula should also be scored against ESSA and any other relevant standards to ensure sufficient alignment.

  • Leverage high-dosage tutoring: For some students, evidence-based curricula should be supplemented with learning recovery programming and practices. To accelerate student learning in reading across all grade levels, launch a high-dosage tutoring program. Effective tutoring generally requires dedicated staff, who should have the capacity to tutor individuals or small groups of students at least three times per week; use of data management tools; and dedicated school time to align lessons and materials with classroom content and curricula.
