To ensure proper funding and compliance with these Principles, states should, in a manner consistent with protecting client confidentiality, collect reliable data on public defense, regularly review such data, and implement necessary improvements. Public Defense Providers should collect reliable data on caseloads and workloads, as well as data on major case events, use of investigators, experts, social workers and other support services, case outcomes, and all monetary expenditures. Public Defense Providers should also collect demographic data on lawyers and other employees. Providers should also seek to collect demographic data from their clients to ensure they are meeting the needs of a diverse clientele. Aggregated data should be shared with other relevant entities and made publicly available in accordance with best practices.
