Question

# What is the difference between a needs assessment and a program evaluation?

A needs assessment comes before a program and asks what a community needs. A program evaluation comes during and after and asks whether the program is working.

In short

A needs assessment comes first and asks what problems a community has and which ones to tackle. A program evaluation comes later and asks whether the program you chose is being delivered as planned and is making a difference. One tells you what to do; the other tells you whether it is working.

## The short version

|
Needs assessment |
Program evaluation |

When |
Before you choose or fund a program |
While the program runs and after |

Main question |
What does our community need most? |
Is our program working, and why? |

Typical data |
Existing data, community surveys, focus groups, key informant interviews |
Program records, participant surveys, outcome measures over time |

Result |
A set of priorities and a plan |
Findings on delivery and results, with recommendations |

## How they fit together

In SAMHSA's Strategic Prevention Framework, assessment is the first step and evaluation is the last, with capacity building, planning and implementation in between. The framework is a cycle, so your evaluation findings feed the next assessment.

## An example

A town worried about youth substance use might start with a needs assessment: a youth survey, local data and conversations with parents and school staff. If vaping stands out, the coalition chooses a prevention strategy and an evaluation then measures whether students' views and vaping rates change over the next survey cycles.

## Frequently asked questions

**Do we need both?**

Often, yes. Many grants expect a needs assessment to justify the program and an evaluation plan to measure it. The assessment's data also becomes the baseline your evaluation compares against.

**Can the same team do both?**

Yes, and it helps. When the same people run the assessment and the evaluation, the measures line up from the start.
