Residential vouchers are for students who are placed in residential treatment centers by state placing agencies and IEP teams. When a state placing agency places a student in a residential treatment center, it is the responsibility of the home school district to determine if the student is eligible or non-eligible for special education per A.R.S. §15-765(E) and A.R.S. §15-1183(B).
"Home school district" means the (age-appropriate) school district or charter school that the child last attended or, if the child has not previously attended a public school in this state, the school district in which the person resides who has legal custody of the child, as provided in section 15-824, subsection B. If the child is a ward of this state and a specific person does not have legal custody of the child or is a ward of this state and the child is enrolled in an accommodation school pursuant to section 15-913, the home school district is the district that the child last attended or, if the child has not previously attended a public school in this state, the school district within which the child currently resides.
