Evidence-Based Policies and Practices

The NYC Department of Probation (DOP) is in the midst of incorporating evidence-based policies and practices into virtually everything we do, from supervision to training to community outreach. DOP is reviewing all of our policies, practices and programs in a systematic, deliberate way to identify the evidence that supports these practices and adjust as necessary.

We are continually meeting with our local, state, and national colleagues to ensure that we are aware of the latest research.

What are Evidence-Based Policies and Practices?

Evidence-based policies and practices (EBPP) use current research and the best available data to guide decisions and produce the outcomes that our stakeholders—probation clients, victims, and communities—expect.

EBPP involve research-tested principles that guide intervention. They also refer to specific intervention models that are proven to lead to good outcomes.

EBPP embraces the use of all available tools, from internal DOP practices to community-based programs to intensive treatment to incarceration.

EBPP is based on the proven premise that the most effective interventions are those that reduce the chance that a probation client will re-offend, which leads to greater public safety.

Evidence-Based Principles Promote Public Safety

An evidence-based approach is not “soft” on crime—in fact, it’s exactly the opposite. Often, requiring a client to confront and change his or her mindset and behaviors is more intimidating than letting him or her “do time” or coast through traditional community supervision.
That being said, DOP recognizes that no single evidence-based intervention is guaranteed to succeed with all target populations, and certainly not in isolation. Helping clients make better choices and take advantage of opportunities is a complex process that depends on a variety of variables. DOP is constantly seeking out new and innovative policies and practices.

Eight Evidence-Based Principles

  1. Assess Risk and Needs
  2. Build Motivation
  3. Target Interventions (Including Treatment and Sanctions) Based on Risk and Needs
  4. Use Cognitive Behavioral Techniques to Teach and Practice New Skills.
  5. Increase Positive Reinforcement
  6. Engage Ongoing Support in Natural Communities
  7. Measure Relevant Processes/Practices
  8. Provide Measurement Feedback


These eight principles reinforce each other.

DOP firmly believes that resources have the most impact when they are focused on moderate to high-risk clients, rather than low-risk clients. This principle is based on a strong foundation of evidence.
