(c) Consistent with the requirements of this section , the child shall be assessed for suitability for residential treatment by a qualified evaluator who has conducted an examination and assessment of the child and has made written findings that:
1. The child appears to have an emotional disturbance serious enough to require treatment in a residential treatment program and is reasonably likely to benefit from the treatment.
2. The child has been provided with a clinically appropriate explanation of the nature and purpose of the treatment.
3. All available modalities of treatment less restrictive than residential treatment have been considered, and a less restrictive alternative that would offer comparable benefits to the child is unavailable.
A copy of the written findings of the evaluation and suitability assessment must be provided to the department, to the guardian ad litem, and, if the child is a member of a Medicaid managed care plan, to the plan that is financially responsible for the child's care in residential treatment, all of whom must be provided with the opportunity to discuss the findings with the evaluator.
