This study compares the effectiveness and efficiency of constant time delay (CTD) and simultaneous prompting (SP) to teach decoding and word reading to four students, 7 to 9 years of age, with intellectual disabilities (ID) in the mild to moderate range. An adapted alternating treatment design was implemented to assess the two methods. The results…

Students with intellectual disabilities need more time and explicit instruction to develop word decoding. Most previous research on interventions among these students is performed in English. Therefore, the current study examined the impact of a word-decoding intervention in Swedish on individual students with intellectual disabilities. A…

Most approaches for teaching reading involve students reading aloud and receiving feedback. These approaches are not feasible for nonspeaking students, and teachers need alternative strategies that do not require speech. To provide guidance about effective strategies, we conducted a systematic review of 51 experimental studies within 36 journal…

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,…

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…

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…
