How to write an evaluation plan: purpose, questions, indicators and data collection

An explanation of evaluation plan components and how to specify purpose, evaluation questions, indicators, data collection, analysis, ethics and use.

Connect the parts of the plan before evaluation begins

Connect the questions, indicators, collection methods, analysis, and use of findings, and agree them with stakeholders. Read the full explanation

Main takeaway

An evaluation plan brings together the purpose, users, evaluation questions, judgment criteria, indicators, data collection and analysis methods, schedule, ethical considerations and use of results. Agreeing it with stakeholders before evaluation helps prevent the work from losing direction later. [1]

An evaluation plan is a blueprint for evaluation. Before starting questionnaire surveys or interviews, agree why the evaluation is being conducted, who will use its results and which questions it will answer.

A good plan is a document usable for implementation and decisions, rather than a thick document. A few pages may suffice for a small program, but the evaluation purpose and data collection plan must be specific.

Connect the elements of the evaluation plan

Build the plan while checking the links between purpose, questions, data collection, and responsibilities.

Core evaluation plan components

Include the background, purpose, users, program overview, evaluation questions, judgment criteria, indicators, data collection and analysis methods, arrangements, schedule, ethical considerations and planned use of results.

Link evaluation questions, judgment criteria, indicators and collection methods. One question may require multiple indicators, and one source may support multiple questions. Traceability of the grounds for judgment matters more than a one-to-one relationship.

  • Evaluation purpose and intended users
  • Program overview and logic model
  • Evaluation questions and judgment criteria
  • Indicators and data collection methods
  • Analysis and reporting methods
  • Schedule, arrangements and ethics
[1]

Prioritize evaluation questions

Too many questions for the evaluation purpose can make it impossible to collect the evidence needed. Effects, reach and improvement can be addressed together, but estimate the design and burden for each question and agree priorities.

Confirm who will use the results for which decisions and prioritize questions needed for those decisions. For example, if deciding whether to continue, effectiveness, reach and value for cost become important.

  1. Identify users of evaluation results
  2. Confirm decisions to be made after evaluation
  3. Identify questions needed for those decisions
  4. Select main evaluation questions according to intended use and collection burden
  5. Set judgment criteria for each question
Practical framework or suggestion

Specify the data collection plan

Indicator names alone are insufficient in an evaluation plan. Specify from whom, when, how and approximately how many records will be collected, and whether existing data or new research will be used.

Decide ethical arrangements at planning, including personal information, consent, audio and video recording, anonymization and retention periods. Evaluation credibility depends on data management as well as methods.

Practical framework or suggestion

Establish stakeholder agreement

Use the evaluation plan as a document of stakeholder agreement rather than treating completion as the end. Check that program staff and managers share an understanding of purpose, questions, data provision burden and reporting timing.

When external evaluators are involved, design must protect both evaluation independence and frontline learning. Agree participant contact arrangements, data access rights, interim reporting and the scope of final-report publication beforehand to avoid later friction.

  • Document who will use results and for what
  • Check data provision burden and deadlines
  • Set procedures for changes during implementation
  • Agree publication scope and anonymization policy
Practical framework or suggestion
Fictional example; not actual results

Assign responsibilities and deadlines for evaluating consultation support

A fictional example for illustration: a plan to review consultation support methods for the next year.

Evaluation questionInformation and methodsResponsibility and timing
Did support reach people who needed it?Consultation numbers by referral route and reasons for non-useReception staff aggregate at month-end
Did people proceed with applications?Check status after 1 month with people who consentResearch staff who do not provide consultation
What should improve?Compare records with users' experiencesThe responsible manager decides at the next planning meeting

What this example supports

Do not include contact details in public records. Record the number who cannot be followed up, reasons for changes to methods and the final decision-maker in the plan.

Common errors in judgment

Assume questions and indicators must always correspond one to one

How to revise: Use a matrix supporting one question with multiple sources of evidence

Reason: One number cannot explain reach or reasons for change.

Change only the success criteria after seeing results

How to revise: Retain the original criteria and record reasons and implications of changes

Reason: This prevents later judgments from becoming selectively favorable.

Put it into practice next

Link main questions to judgment criteria, sources, responsibilities and deadlines

Frequently asked questions

How many pages should an evaluation plan have?

Follow the recipient's requirements where specified. Otherwise, use sufficient length to make purpose, questions, judgment criteria, collection, responsibilities and use clear, and place questionnaires and similar instruments in appendices.

Who writes an evaluation plan?

The evaluation lead drafts it and obtains agreement from program staff, managers, frontline staff and, as needed, external evaluators and stakeholders.

Can an evaluation plan change during implementation?

Yes. However, record the reasons, date and affected indicators or collection methods.
