Intervenors & Intervention
Deafblindness – A Definition
A student with deafblindness is one who has a combined loss of vision and hearing, such that neither sense can be used as a primary source of accessing information. Therefore, deafblindness is considered an information-gathering disability.
The student with deafblindness requires specialized support to meet his/her educational needs beyond those that would be provided for students with solely vision loss or hearing loss or severe disabilities. With this support in place, the student with deafblindness is able to benefit from integrated school and community programs.
The student with deafblindness is not a student with a visual impairment who cannot hear,
nor a student with hearing loss who cannot see.
Deafblindness is a unique disability.
Intervention is a process that allows an individual who is deafblind to receive visual and auditory information that s/he is unable to gather on his/her own. This process must be meaningful to the individual with deafblindness, so s/he can interact with his/her environment. Intervention enables the person who is deafblind to establish and maintain control over his/her life.
The concept of Intervention for individuals with deafblindness was developed in Canada and has been adopted worldwide. Click here to read The Principles of the Canadian Concept of “Intervention.”
An Intervenor is a professional who provides Intervention services to an individual who is deafblind.
“Intervention is not defined by the person acting as the Intervenor, but rather by the needs of the person who is deafblind.”
