This report, which was mandated by The Justice for All Reauthorization Act of 2016, details the results of a national needs assessment of forensic science service providers conducted in 2017 and 2018. The needs assessment focused on services provided by forensic laboratories, medical examiner and coroner offices, and other forensic science service providers. As forensic analyses have expanded and become more sensitive, and as practitioners have established more evidence-based policies and capabilities, the broad demand for forensics has grown. Forensic laboratories and medical examiner and coroner offices are constantly working to address the needs of the field, balancing operational priorities to meet stakeholder requests while introducing innovative solutions to solve emerging criminal justice questions. This needs assessment compiled demonstrative evidence of how the field is adapting to advancements in technology, the volume and types of forensic evidence, and the evolving needs of the justice system.
