How to write an indicator reference sheet

By the EMPOBase team · · 4 min read

Short answer

An indicator reference sheet is a one-page record for a single indicator. It states the exact definition, the formula, the data source, how often you collect it, who collects it, how it is broken down by group, and its known limits. Write it before data collection starts, so every officer counts the same thing in the same way across sites and reporting periods.

Key points

  • One sheet per indicator, written before the first data is collected.
  • The definition must say what counts and what does not; the formula must be something a new officer could repeat.
  • Name the data source, the collector and the frequency, so no one has to guess.
  • Version the sheet and record why each change was made.

Why does an indicator need a reference sheet?

Take the indicator “number of people trained”. One officer counts everyone who walked in. Another counts only people who attended all three days. A third counts the same person once for each course. The numbers look alike in a report, but they mean different things.

A reference sheet stops this. It writes down, in one place, what the indicator means and how to produce it. New staff can follow it. A reviewer can check a result against it. A donor can see that the figure follows a stable rule.

What fields should the sheet contain?

Keep the sheet to one page. These fields cover most needs.

FieldWhat to write
Indicator nameThe exact wording used in the results framework
Result levelOutput, outcome or impact
DefinitionWhat counts, what does not, and key terms explained
UnitPerson, household, session, item, percent
FormulaNumerator and denominator, or the counting rule
Data sourceAttendance sheet, survey, registry, partner report
Method and frequencyHow and how often the data is collected
ResponsibleThe role that collects, and the role that checks
DisaggregationGroups to break the result down by
Baseline and targetValues and the dates they apply to
LimitsKnown weaknesses, such as self-reported data
VersionNumber, date and a short change note

How do you write a clear definition?

A good definition lets two people reach the same number. Use this order:

  1. Name the thing counted. “A person who completed at least two of three training sessions.”
  2. Say what is excluded. “Staff of partner organizations are not counted.”
  3. Define the hard words. If you write “vulnerable household”, say how you decide.
  4. Set the time window. “Counted in the quarter in which the third session ended.”
  5. Say how to handle repeats. Decide whether a person who attends twice counts once or twice, and write it down.

If the definition needs a paragraph, the indicator may be trying to measure too much. Consider splitting it in two.

How do you state the formula?

For a count, the formula is the counting rule: “Total number of unique participants who meet the definition.” For a percentage, give both parts:

  • Numerator: households that report eating two or more meals a day.
  • Denominator: all households surveyed in the round.
  • Result: numerator divided by denominator, times 100.

State what happens when the denominator is zero or the data is missing. A rule written now saves an argument later.

Where does the data come from, and who is responsible?

Name the source in plain terms: “signed attendance sheets entered by the training officer”, or “household survey of a random sample”. Then name the roles:

  • Collector: the person who gathers the raw data.
  • Checker: the person who reviews it before it counts.
  • Owner: the person who answers questions about the indicator.

Use roles, not personal names, so the sheet survives staff changes. Our article on how to check field data quality covers the checker’s job in detail.

What should you do about disaggregation and limits?

List the groups you will break the result down by, such as sex, age band and disability status. Keep the list short and only include breakdowns you can really collect. The article on disaggregating by sex, age and disability explains how to choose.

Then write the limits honestly. “Data is self-reported.” “Only people with a phone can be reached.” A limit stated in the sheet is a caveat. A limit found later by a donor is a problem.

How do you keep the sheets current?

Treat each sheet as a controlled document.

  • Give it a version number and a date.
  • Record every change, with the reason and who approved it.
  • Say whether earlier results can still be compared with new ones.
  • Review all sheets at the start of each reporting year, and when a donor changes its requirements.

Store the sheets where the whole team can read them. A sheet that sits on one person’s laptop is not a standard.

Where EMPOBase fits

EMPOBase includes a library of 235 indicators in 8 sectors. Each entry has a definition, means of verification and disaggregation guidance that you can adapt for your own sheet. You review and adapt the wording to your donor’s requirements; the library is a starting point, not a certification of compliance. The library text does not create an automatic live link between a results framework row and indicator results. You can see how indicators are organized on the indicators page, or look at how the field-to-results workflow handles data once it is collected.

Questions people ask

Who should approve an indicator reference sheet?

The MEAL lead usually writes it, and the project manager signs it off. If a donor set the indicator, check that your wording matches the donor's definition.

Is an indicator reference sheet the same as a PIRS?

Yes, in most cases. PIRS stands for performance indicator reference sheet, a name used by some donors. Other organizations say indicator definition sheet or indicator protocol.

Can we change a definition during the project?

Yes, but treat it as a controlled change. Record the old and new wording, the date and the reason, and say whether earlier figures are still comparable.
