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…

Understanding the early literacy abilities of children who use augmentative and alternative communication (AAC) is essential for designing and testing methods of reading intervention focused on printed orthography. School-based professionals need assessments that measure word reading skills of students with heterogenous speech and physical…

Purpose: This study aimed to elucidate the nature of the relationship between the development of decoding and encoding skills in the first year at school. Method: The foundational literacy skills of one hundred eighty 5-year-old children were examined on three occasions over their first year of literacy instruction. Participants received the same…

Irregular words cannot be read correctly by decoding letters into sounds using the most common letter-sound mapping relations. They are difficult to read and learn. Cognitive models of word reading and development as well as empirical data suggest that inhibitory control might be important for irregular word reading and its development. The…

Learning to read is one of the most important components of education and literacy skills in early childhood have a significant impact on later reading success. There is an abundance of quantitative research focused on reading, known as the science of reading. However, gaps and flaws have been identified in the research, indicating that an…

Since 2012, when preparatory grade (PG) became compulsory in Romania for 6-year olds, little understanding has been gained of how children's literacy evolves in PG, although over the same period, Romanian 15-year olds' reading performance has shown no signs of improvement (Noveanu et al., 2023). Children enter school with broadly varying literacy…

Learning to read English is more difficult than in most other alphabetic languages. It sometimes seems there are not reliable rules for linking letters with sounds. Teaching students all of the letter patterns they may find in texts is no simple task. Students struggle processing the sounds in words, so even words with simple spellings are…

Background: Failure to learn early reading skills leads to lower reading comprehension later in elementary school (Double et al., 2019; Paige et al., 2019), which can then lead to poverty, underemployment, and increased likelihood of being incarcerated (World Literacy Foundation, 2018). Early reading skills are best developed in kindergarten…

This study explored the effects of instruction in letter sound correspondence (LSC) with four preschool students with disabilities. The study included participants with developmental delay, autism spectrum disorder, and communication disorders. Researchers incorporated nonverbal methods of response to accommodate study participants with…

The author reviews theory and research by Ehri and her colleagues to document how a scientific approach has been applied over the years to conduct controlled studies whose findings reveal how beginners learn to read words in and out of text. Words may be read by decoding letters into blended sounds or by predicting words from context, but the way…

This study examined the response of two students in the Southwestern United States with autism spectrum disorder and IQ in the intellectual disability range to a comprehensive, text-based reading intervention. The intervention, "Friends on the Block," includes multiple strands of literacy providing explicit instruction in phonics,…

Difficulties in writing can emerge as early as preschool, and often coincide with developing difficulties in reading (Berninger et al., 1997; Graham & Santangelo, 2014; Graham et al., 2020), as reading and writing are fundamentally connected skills (e.g., Fitzgerald & Shanahan, 2000). Writing instruction in general has had positive effects…

The purpose of this study was to analyze published decoding tests, at the item level, to determine what decoding skills and discrete letter-patterns are assessed, and identify potential instructional implications of these measures. Twenty published word list decoding tests, either used in research or within a Multi-Tiered Systems of Supports…

Purpose: Reading and writing are foundational skills that provide access to educational, vocational, and social experiences. However, while the gap widens between the literacy skills of individuals with intellectual disability (ID) and those with typical development as they grow into adolescence, little is known about meeting the comprehensive…

Previous meta-analyses highlight the role of executive functions (EF), encompassing working memory, task-switching, and inhibition, in reading comprehension, but have not demarcated its role in decoding, defined as use of orthographic patterns to access oral pronunciations. According to the dual-route model, decoding involves parallel activation…
