Public Safety Assessments (PSA) & Scoring Breakdown in New Jersey

Introduction: What is a Public Safety Assessment (PSA)?

When an individual is arrested and booked into a county facility in New Jersey, a judge deciding their fate at an initial appearance does not rely purely on intuition. Under the state’s Bail Reform framework, the court utilizes a standardized, algorithm-driven tool known as the Public Safety Assessment (PSA).

Developed to remove human bias, socioeconomic prejudice, and subjective guessing from the pretrial process, the PSA evaluates an individual’s criminal history record to predict risk.

Because this single document heavily influences whether a prosecutor moves for pretrial detention or what monitoring conditions a judge imposes, understanding how the PSA is calculated is critical. The defense attorneys at William Proetta Criminal Law routinely audit these assessments to catch algorithmic or clerical errors that could otherwise keep a client wrongfully locked behind bars.

The 9 Core Factors Evaluated by the PSA Algorithm

The PSA does not look at your race, gender, wealth, education, or neighborhood. Instead, it processes data pulled strictly from adult criminal records and court appearance histories across nine specific factors:

  1. Age at Current Arrest: Evaluates the defendant’s age bracket at the time of the offense (e.g., younger cohorts versus older adults).

  2. Current Violent Offense: Evaluates whether the current charge involves an actual attempt to cause, or the intentional infliction of, physical injury.

  3. Pending Charges: Checks whether the defendant had any active, unresolved criminal cases pending at the time of the new arrest.

  4. Prior Disorderly Persons Convictions: Accounts for prior lower-level misdemeanor convictions handled in New Jersey municipal courts. (Note: Petty disorderly persons offenses and traffic violations are excluded).

  5. Prior Indictable Convictions: Counts prior felony-level convictions on the defendant’s record.

  6. Prior Violent Convictions: Specifically flags historical convictions involving acts of real violence or severe bodily harm.

  7. Prior Failures to Appear (FTA) within the Last 2 Years: Measures recent instances where the individual skipped a scheduled pre-trial court date.

  8. Prior Failures to Appear (FTA) Older than 2 Years: Looks at older historical patterns of missing court appearances.

  9. Prior Sentences to Incarceration: Evaluates whether the defendant has previously served a jail or prison sentence exceeding 14 days.

The Output: Risk Scores and Flags

Once the algorithm processes the nine factors, it generates two distinct numerical risk scores scaled from 1 to 6 (where 1 indicates the lowest risk and 6 indicates the highest risk), alongside a vital safety flag:

  • Risk of Failure to Appear (FTA Score): Predicts the statistical probability that the defendant will fail to show up for future scheduled court hearings.

  • Risk of New Criminal Activity (NCA Score): Predicts the statistical probability that the defendant will pick up a new criminal offense if released prior to trial.

  • The New Violent Criminal Activity (NVCA) Flag: This is a binary indicator (Yes or No). If the defendant’s background data meets specific thresholds for past violent behavior, the system assigns an NVCA flag, alerting the judge and prosecutor to an elevated potential safety risk.

Why PSAs Are Often Wrong (And How We Fight Them)

Because the PSA is entirely automated, it is only as accurate as the data fed into it. State and county criminal databases frequently suffer from administrative oversights that artificially inflate a defendant’s risk scores. Common errors include:

  • Un-updated Expungements: Showing historical arrests or convictions that were legally expunged and should no longer be factored into the equation.

  • Misclassified Charges: Automatically categorizing a non-violent municipal or property offense as a violent crime.

  • Incorrect FTA Tracking: Crediting a missed court date to a defendant when the notice was actually sent to an old address or where an appearance was rescheduled administratively.

An inflated PSA score can trigger a harsh detention recommendation or push a defendant into restrictive Level 3 electronic monitoring. When you retain William Proetta Criminal Law, we immediately scrutinize the raw data behind your PSA. Exposing these administrative errors to the judge can drastically lower your risk profile and open the door to immediate release.
