How differentiated can a new tablet-based reading screening measure the reading proficiency of students with intellectual disabilities? Comparing the impact of disability, disability type and grade level on reading skills

Abstract

All people have the right to learn reading. Understanding the factors influencing reading proficiency among students with intellectual disabilities is important for developing effective instructions. To accurately assess reading, suitable assessments that can effectively differentiate between low performance levels are necessary. We analyse results of 400 students (43 students with intellectual disabilities) in a digital reading screening and investigate the influence of disability severity, grade level and special educational needs status on the reading abilities of students with intellectual disabilities. The results indicate that the screening is suitable for assessing students with intellectual disabilities. A newly developed digital screening test for flash reading measures reliably. All presumed factors significantly impact the reading proficiency. However, substantial overlap exists between students with intellectual disabilities and those with other special needs. The necessity for structured reading interventions, irrespective of the disability label, and the importance of appropriate assessments for all students are discussed.
