The purpose of this article is to describe recommendations for providing evidence-based literacy instruction to students with intellectual and developmental disabilities (IDD), including students with comorbid autism spectrum disorder (autism). We identify six evidence-based practices, highlight key research that supports each practice, and then…

For the purpose of this article within this special issue on Structured Literacy™, we were asked to address the code-focused skills of phonemic awareness and word reading. Findings from research studies converge to show that explicit and systematic instruction helps most students understand how speech sounds, or phonemes, map to letters and…

Fluency with skills that operate below the word level (i.e., sublexical), such as phonemic awareness and alphabetic knowledge, may ease the acquisition of decoding skills (Ritchey & Speece, 2006). Measures of sublexical fluency such as phoneme segmentation fluency (PSF), letter naming fluency (LNF), and letter sound fluency (LSF) are widely…

The UPSTART Summer program is a federally funded i3 validation project that uses a computer-based program to maintain and develop the literacy skills of elementary school students in rural Utah during the summer months when school is out of session. Researchers used a quasi-experimental design to evaluate the impact of the program in forestalling…

Purpose: Preschoolers' phonological awareness (PA) and alphabet knowledge (AK) skills are two of the strongest predictors of future reading. Despite evidence that providing at-risk preschoolers with timely emergent literacy interventions can prevent academic difficulties, there is a scarcity of research focusing on Latinx preschoolers who are Dual…

This study addressed two areas of inquiry: 1) the influence of enlisting three underlying cognitive learning processes (CLPs) in alphabet learning, and 2) order effects for letter name and letter sound instruction. Alphabet instruction was designed to enlist Paired Associate Learning (PAL) only, PAL plus Orthographic Learning (OL), or PAL plus…

In this chapter, we examine adult- and child-focused models of reading with respect to cognitive processing deficits associated with low literacy. We examine influential integrative models of reading and reading comprehension. We then review the empirical literature on components of reading ability, subdivided into three categories: language…

Although publicly-funded prekindergarten (pre-k) programs have been designed to promote children's school readiness, programs have tended to support early literacy skills to a greater degree than early language skills. Given the importance of both language and literacy skills for children's reading acquisition and academic achievement, the present…

This paper presents findings of an efficacy trial examining the effect of a multi-tiered instruction and intervention model on first grade, at risk students' reading outcomes. Schools (n = 16) were randomly assigned to the treatment or control condition. In the fall of Grade 1, students were assigned to an instructional tier on the basis of SAT-10…
