By April 1, 2008, the Judicial Council shall adopt, through rules of court, performance measures designed to complement and promote those measures specified in Section 16544 so that courts are able to measure their performance and track their own progress in improving safety, permanency, timeliness, and well-being of children and to inform decisions about the allocation of court resources. In adopting performance measures, the Judicial Council shall consult with the council and the secretary. The performance measures shall be based on data that is available from current or planned data collection processes and to the greatest extent possible, shall ensure uniformity of data reporting.
