Risk vs Needs Assessments

Module 1 · Risk Needs Tool Lessons

Prediction is not the same as intervention.

Risk assessment and needs assessment are related, but they are not the same thing. One asks how likely an outcome is. The other asks what factors should be targeted for intervention.

Key takeaway

Good prediction does not automatically tell us what to treat.

What Risk Assessment Asks

A risk assessment asks:

The question: How likely is an outcome?

Examples include:

  • recidivism
  • violence
  • failure to appear

These tools are often used to inform:

  • supervision intensity
  • classification
  • release decisions

Risk and needs assessments ask different questions

Risk assessment focuses on how likely an outcome is. Needs assessment focuses on what factors should be targeted for intervention.

Comparison of risk assessment and needs assessment questions, examples, and uses

Some dynamic criminogenic needs can do both, but prediction and intervention are still different tasks.

What Needs Assessment Asks

A needs assessment asks a different question:

The question: What factors should we target for intervention?

Examples include:

  • substance use
  • peer associations
  • employment
  • antisocial cognition

These tools are used to guide:

  • treatment planning
  • programming
  • case management

Some Factors Do Both

Some factors do both. Dynamic criminogenic needs can:

  • predict recidivism
  • serve as intervention targets

That overlap matters, but it does not make prediction and intervention the same thing.

Why This Matters

  • Prediction is not the same as intervention
  • Some strong predictors are not easily changeable
  • Effective correctional practice requires both risk and needs assessment

Bottom Line

Good prediction does not automatically tell us what to treat. Risk assessment helps estimate likelihood; needs assessment helps identify intervention targets.
