As part of a larger effort to create standards for psychosocial care of children with cancer, we document consensus and evidence‐based data on interprofessional communication, documentation, and training for professionals providing psycho‐oncology services. Six databases were searched. Sixty‐five articles and six guidelines and consensus‐based documents were identified; 35 met inclusion criteria. Data support strong recommendations for standards of care in communication/collaboration, documentation of patient information, and training in pediatric psycho‐oncology. These are areas where extensive research is unlikely to be conducted; however, professional expectations and qualifications may be further clarified and strengthened with time.
