Pretrial Risk Assessment

The federal Pretrial Risk Assessment (PTRA) is a scientifically based instrument developed by the Administrative Office of the U.S. Courts (AO) and used by United States probation and pretrial services officers to assist in determining a defendant’s risk of failure to appear, new criminal arrests, or technical violations that may lead to revocation while in the pretrial services system.

In conjunction with a thorough pretrial services investigation, the PTRA helps officers make well-informed decisions when making release or detention recommendations to the court. Officers’ investigations and recommendations represent critical components in the criminal justice process to reasonably ensure the future appearance of defendants in court, while ensuring the safety of the community.

The United States probation and pretrial services system embraces evidence-based practices (EBP), which employ the best available scientific data to influence release and detention decisions. A key element of the evidence-­based approach is the use of risk assessment instruments to achieve maximum, measurable reductions in pretrial failure rates.

Using the PTRA in combination with their professional judgement, officers can make informed decisions about which people are suitable for release recommendations and help inform possible supervision strategies.

The PTRA gives officers an accurate, evidence-based assessment of:

A person’s statistical risk of :

Failing to appear.

Revocation for a technical violation

or sustaining an arrest for new criminal activity.
