The State Board of Education shall establish standards for temporary or permanent exclusion from the public school of children who are found to be uneducable and untrainable in the public schools. Any child who is reported by a person who is certified as a public school psychologist as being uneducable and untrainable in the public schools, may be reported by the board of school directors to the Superintendent of Public Instruction¹ and when approved by him, in accordance with the standards of the State Board of Education, shall be certified to the Department of Public Welfare² as a child who is uneducable and untrainable in the public schools. When a child is thus certified, the public schools shall be relieved of the obligation of providing education or training for such child. The Department of Public Welfare shall thereupon arrange for the care, training and supervision of such child in a manner not inconsistent with the laws governing mentally defective individuals.
