The local welfare agency shall conclude the family assessment or the investigation within 45 days of the receipt of a report. The conclusion of the assessment or investigation may be extended to permit the completion of a criminal investigation or the receipt of expert information requested within 45 days of the receipt of the report.
For the purposes of this chapter, except for section 260E.37, a determination that child protective services are needed means that the local welfare agency documented conditions during the assessment or investigation sufficient to cause a child protection worker, as defined in section 260E.37, to conclude that a child is at significant risk of maltreatment if protective intervention is not provided and that the individual or individuals responsible for the child's care have not taken or are not likely to take action to protect the child from maltreatment or risk of maltreatment.
