Children with typical hearing and vision learn to communicate by watching and listening to others. But children who are deafblind have limited access to learning this way. They need knowledgeable educators who understand how deafblindness impacts learning--who know how to assess a child's communication and plan for and engage in meaningful…

This NCDB Practice Guide outlines the essential components and associated skills for building trusting relationships with children who are deaf-blind. Relationships grounded in trust and mutual respect increase opportunities for learning and communication. They create a sense of safety, minimize anxiety, and empower individuals to explore and…

Introduction: This study examined the interstate variability in eligibility criteria for the disability category of deafblindness. Methods: We systematically reviewed and coded information related to the location of state data, the use of federal language in state definitions, additional eligibility criteria (i.e., disability eligibility…

Very little is known about how unidentified dual sensory loss (DSL) may affect education and academic outcomes for students with extensive support needs (ESN). We used data from a teacher survey on over 100,000 students with ESN who take U.S. statewide alternate assessments to identify the number of students with known and suspected DSL and the…

This brief, co-produced by the National Center on Deaf-Blindness (NCDB) and Accessible Teaching, Learning, and Assessment Systems (ATLAS), provides important information about students with dual sensory loss who also have significant cognitive disabilities, as well as recommendations for identification and implications for instruction. The…

Youth with deaf-blindness have difficulty transitioning to adulthood and experience poor employment outcomes, yet research on this population is limited. To identify predictors of postschool employment outcomes for transition-age youth who are deaf-blind, we conducted multiple logistic regression analyses using data from Waves 1 through 5 of the…

The field of deafblind (DB) education has a long and rich history which includes a lack of qualified personnel to meet the needs of the population of learners. In addition, the literature base is small, lacking evidence for effective practices or methods of assessing and tracking growth with these learners. The ability to adequately track student…

The High Quality Communication intervention aims to stimulate interpersonal communication between individuals with congenital deaf-blindness (CDB) and their social partners. Found effective in multiple-case experiments, the intervention is based on Trevarthen's theory of intersubjective development (Bråten & Trevarthen, 2007), which describes…

Introduction: In this study, we applied the Intervention Model for Affective Involvement (IMAI) to four participants who are congenitally deafblind and their 16 communication partners in 3 different settings (school, a daytime activities center, and a group home). We examined whether the intervention increased affective involvement between the…

This report describes a project that uses existing data sets to describe the population of students with significant cognitive disabilities and known or suspected dual sensory loss. It includes students with suspected dual sensory loss because students with significant cognitive disabilities are reported to have unidentified sensory loss (Erickson…

Sensory disabilities may limit a person's development of intersubjectivity, that is, the awareness of self and other, which develops in conjunction with interpersonal communication. This study used intersubjectivity theory to test a new intervention called the High-Quality Communication (HQC) intervention for its effects on a young adult with…

Introduction: This study utilized wait-time procedures to determine if they are effective in helping children with deafblindness or multiple disabilities that include a visual impairment communicate in their home. Methods: A single subject with an alternating treatment design was used for the study. Zero- to one-second wait time was utilized…

This technical report synthesizes the process and information used by National Consortium on Deaf-Blindness (NCDB) in the development of a consistently applied definition of intervener services. It addresses challenges and questions, provides comparisons between interveners and paraprofessionals, and offers definitions, roles and concepts used by…

It is widely recognized that the 12 percent of all youth in American public schools who have disabilities comprise a set of students with distinct capacities and needs. Federal legislation, including the most recent updates to the Individuals with Disabilities Education Act (IDEA) in 2004, identifies different disability groups and mandates that…

The National Longitudinal Transition Study 2012 (NLTS 2012) is the third in the series of NLTS studies sponsored by the U.S. Department of Education to examine youth with disabilities receiving services under the Individuals with Disabilities Education Act (IDEA), a long-standing federal law last updated in 2004. Under IDEA, youth with…
