(a) "Acceptable documentation" means written reports or statements that are directly related to adaptive functioning, reasonable considering the evidence, and from a qualified professional. The determination of whether a document is acceptable is made by DDA.(b) If no documentation is provided or DDA determines that the documentation is not acceptable DDA may deny eligibility.
