Practical evaluation guide

What is an evaluation indicator? Types, examples, development and differences from KPIs

Organize program and nonprofit evaluation indicators through types, examples and differences from KPIs. Includes a definition table for numerators, denominators, missing data and collection responsibilities, and fictional consultation-support entries. Use the free worksheet to specify your own indicators.

Turn questions into observable indicators

For proportions, make the numerator and denominator explicit. Keep indicators separate from target values that specify how far you aim to go. Read the full explanation

Main takeaway

An evaluation indicator expresses a change or implementation condition of interest in observable terms. Indicators can be qualitative descriptions as well as numbers. A good indicator corresponds to an evaluation question, defines the period, what is being judged and how data will be obtained, and specifies the numerator and denominator for proportions, so that it can inform decisions after collection. Keep targets describing the desired level separate. [1]

An evaluation indicator expresses a change or implementation condition of interest in observable terms. It concerns what to measure and is treated separately from a target defining the desired level.

Start by deciding the questions the evaluation should answer, rather than listing indicators. Adding indicators while questions remain vague can produce data without enabling judgment. This guide covers indicator types, development steps, characteristics of good indicators and practical selection checks. It explains evaluation of programs run by municipalities, nonprofits and similar organizations.

Create indicators that fit the question

Distinguish types of indicators and specify what to observe and how to measure it.

Indicator types and development from questions

Indicator types differ according to the program stage being examined. The table below is this site's practical classification. Names and categories vary by scheme and grant form, so prioritize the recipient's terminology.

After understanding the types, develop indicators from evaluation questions. If the question is whether training changed participants' practice, satisfaction is insufficient. Candidates include how often participants practiced afterward, products they created and sharing with supervisors or colleagues.

Conversely, if the question is whether the program is reaching the intended group as planned, process indicators such as participation rates, target characteristics, attrition and delivery counts become important.

Differences between output and outcome indicators

This guide distinguishes indicators of delivery volume from indicators of changes for the target group. Consultation counts and material distribution counts establish how much was delivered; behavior after consultation and similar measures examine subsequent change.

The table below is this site's classification example. The OECD's 2023 glossary includes changes in knowledge and skills directly produced by activities within Outputs, so classification may differ from this table, which treats learning as a short-term outcome. Check the recipient's definitions.

Output indicatorsWhat was done or providedTraining sessions, participants and consultations
Initial outcome indicatorsChanges in understanding, awareness and confidenceUnderstanding tests, self-efficacy and knowledge scores
Medium-term outcome indicatorsChanges in behavior and practiceFrequency of practice, products created and actions after consultation
Long-term outcome indicatorsChanges in conditions and resultsEmployment retention, learning attainment and organizational improvement
[2]

Characteristics of good indicators

Good indicators can inform decisions as well as be measured. Selecting them solely because numbers are easy to obtain can move the evaluation away from the changes of real interest.

Limit indicators to those needed to answer the questions. There is no fixed appropriate count. Test who records information and how many minutes it takes, and review indicators unused in decisions or excessively burdensome.

  • Directly corresponds to an evaluation question
  • Clearly identifies what changes and for whom
  • Data sources and collection methods are feasible
  • Can inform judgment or improvement after collection
  • Distinguishes short-, medium- and long-term horizons
[1]

Indicator definition table: align measurement conditions

Where there are multiple candidates, imagine how evaluation results will be used rather than considering ease of measurement alone. It may be necessary to exclude from the main indicators numbers that cannot inform meeting decisions, do not lead to improvement, or are too costly to collect.

Quantitative indicators alone may not reveal why change occurred. Combining main outcome indicators with qualitative information such as open responses, brief interviews and case records makes interpretation and consideration of improvements easier.

Indicator names alone do not ensure comparable aggregation. The table below contains entries proposed by this site. Specify calculation conditions for quantitative indicators and what to record and how to judge it for qualitative indicators. Do not fill gaps by guessing; assign responsibility and timing for checking them.

  • The indicator can answer the evaluation question
  • Staff use consistent data definitions
  • Collection frequency and responsibility assignments are feasible
  • Improvement actions can be anticipated after reviewing increases or decreases

Data sources and collection responsibilityConsultation staff check follow-up records obtained with consentCheck participant burden and information handling
Judgment criteria and targetsAgree these with stakeholders beforehand and keep them separate from observed resultsDo not turn the observed result of 9 people into a target
Use and limitations of resultsCheck barriers to starting applications and review supportDo not infer a causal effect of consultation from the proportion alone
Practical framework or suggestion
Fictional example; not actual results

Make progress toward applications countable

A fictional example for illustration: define delivery volume and behavioral change in follow-up of consultation support.

ItemExample entryReason
IndicatorNumber starting an application within 1 month of consultationFix the period between consultation and checking
Denominator20 follow-up targets, 15 with known statusKeep the 5 unconfirmed cases visible
Illustrative result9 of 15 started60% of those with known status
Supplementary informationClassify reasons people could not startConsider improvements in light of changes in counts
Proportion with known status15 of 20, or 75%Also state the scope for which status is known

What this example supports

Do not treat people whose status is unconfirmed as zero or remove them from the denominator without explanation. Keep targets and observations in separate fields. The 60% from 9÷15 is the proportion among people with known status. The proportion of all 20 targets confirmed as starting is 9÷20, or 45%, but with 5 unconfirmed people it is not the actual starting proportion for the entire target group. These numbers alone also cannot establish the effect of consultation.

Common errors in judgment

Use easily measured satisfaction as the only main indicator

How to revise: If application behavior is the concern, check starting status and barriers

Reason: This prevents mismatch between questions and indicators.

Write only utilization rate and let staff use different denominators

How to revise: Define the period, numerator, denominator, exclusions and missing-data treatment

Reason: The same name can otherwise represent different numbers.

Frequently asked questions

What is an evaluation indicator?

An item expressing changes or implementation conditions of interest in observable terms. It can be a qualitative description as well as a number. An indicator specifies what to measure and is kept separate from a target specifying the desired level.

Are KPIs and evaluation indicators the same?

They overlap but are not identical. KPIs are key management indicators, while evaluation indicators provide evidence for answering evaluation questions.

Is satisfaction an outcome indicator?

Satisfaction is useful supplementary information but weak evidence of outcomes on its own. Combine it with changes in understanding, behavior and conditions.

How many indicators are needed?

There is no universally appropriate count. Select indicators needed for the main questions and adjust the volume so that those responsible can sustain collection and analysis.
