The Australian Institute of Family Studies was contracted by the National Child Protection and Support Services (NCPASS) Data Group to undertake the Review of Data Comparability Project. The aims of the Project were to:
• Examine the rates of total notifications, investigations and substantiations, and the rates of children on orders and in out-of-home care for the period 2000–01 to 2005–06;
• Analyse the differences in rates across jurisdictions, and the differences in rates over time within jurisdictions; and
• Identify and assess factors that may explain differences in rates across jurisdictions and within jurisdictions over time.
