In 2007, the Early Hearing Detection and Intervention (EHDI) law was passed in Minnesota mandating newborn hearing screening. Recognizing that a number of state-level agencies and statewide advocacy and direct services organizations share responsibility for serving deaf, deafblind, and hard of hearing children and youth, the Minnesota Commission of the Deaf, DeafBlind & Hard of Hearing (MNCDHH) formed a Collaborative stakeholder group to create positive, systemic changes in order to achieve better education, language acquisition, and career outcomes for students who are deaf, deafblind, and hard of hearing. MNCDHH is a governor-appointed Commission that advocates for communications access and equal opportunity with Minnesotans who are deaf, deafblind, and hard of hearing. The 5-Year Collaborative Plan is a strategic plan that is facilitated by MNCDHH to support and guide the work of this Collaborative. Wilder Research was contracted by MNCDHH to help create a data-driven Collaborative Plan. This report summarizes results of the background research completed to inform the Plan, including a review of the landscape of existing services and supports; the characteristics of children in Minnesota who are deaf, deafblind, and hard of hearing; and the strengths and needs of the service system.
