The department shall examine all information concerning the person for whom admission is requested and shall determine therefrom whether the person is a person with an intellectual disability and whether residence in the residential facility is necessary for the welfare, care, treatment, or training of such person. Such determination shall be made in writing and shall set forth the reasons for the determination. If at any time it shall become necessary, for want of room or other cause, to discriminate in the admission of persons with an intellectual disability to residential facilities, the selection shall be made as follows:
