Florida Outreach Project for Individuals with Deaf-Blindness is funded through the United States Department of Education, Office of Special Education and Rehabilitative Services. The Project is designed to build the capacity of the local school districts to create solutions to educational challenges often associated with students who experience both vision and hearing impairments. The Florida Outreach Project addresses three critical areas in the education of individuals with deaf-blindness:

• Identification of persons with deaf-blindness and maintenance of the deaf-blind census in the State of Florida and the U.S. Virgin Islands;
• Technical assistance and support to families, teachers, and others who live and work with individuals who are deaf-blind in Florida and the U.S. Virgin Islands;
• Training for families, school districts, and service providers.
