This updated guide is recommended for use by reviewers and those conducting all levels of quality assurance (QA) to ensure that OSRI data are accurate, complete, and consistent. It contains information regarding general and item-specific issues to consider when reviewing a case or conducting QA on an OSRI. The guide also describes an approach to conducting QA that encourages discussions with reviewers before completion of the OSRI in addition to a final QA review of the instrument once it is completed. A new section, "Instructions for Foster Care Cases Involving a Trial Home Visit (THV)," provides guidance when rating foster care cases in which the target child or their sibling(s) went home on a trial home visit during the period under review. The English version is available now. A Spanish update will be posted soon.
