When we talk about impact indices we are referring to recognized frameworks that organize and standardize indicators (international, regional, national, among others) to measure programs and report results. Think about references such as SDG, IRIS+ or GRI, these help to compare, dialogue with funders and be accountable. But there is a challenge: balancing standardization and local relevance. Here we explain which frameworks exist, when it is convenient to use them and how to decide indicators judiciously, without losing the context of each evaluation.

What do we mean by impact indices?

In the social and environmental sector, there are catalogs and frameworks that define indicators, methodologies and quality criteria to measure. We call that here impact indices: shared references that facilitate comparability, consistency and traceability between organizations and countries.

To locate us, social impact is changing the lives of others. Impact assessment is measuring how it changes the lives of others. In a complete measurement, we distinguish outputs (what happens immediately), results (what takes time to happen), and impacts (what changed in the lives of others). Indices provide lists and criteria for selecting indicators at each level and documenting how they are measured.

Use indexes to speak common language, but don't sacrifice the relevance of context.

Most used frameworks and standards

Below is a practical overview of frequent references. It is not an exhaustive list, but it is a guide to choose well according to your needs:

  • SDG (Sustainable Development Goals, UN): Global framework with official goals and indicators by theme (poverty, education, climate, etc.). Useful for aligning programs with national and international agendas and reporting contribution to goals. When to use it: when your funder requires SDG alignment or you seek to communicate impacts in a universal language.
  • IRIS+ (GIIN): Taxonomy of indicators for impact investment by objective, sector and business model; includes definitions, calculation methods, and suggested sources. When to use it: if you need consistent indicators for portfolios, social enterprises or funds with impact thesis.
  • GRI (Global Reporting Initiative): Standards for sustainability reports (material issues, metrics, disclosure). Although it was created for companies, it is used in foundations and public-private alliances. When to use it: when you must integrate social/environmental performance into broad and governance reports.
  • IMP, Impact Management Standards / Impact Frontiers: Approach to defining “what, who, how much, contribution and risk” of impact. Helps structure measurement and attribution logic. When to use it: if you want a conceptual framework to prioritize indicators and demonstrate contribution.
  • OECD-DAC (Evaluation Criteria): Relevance, effectiveness, efficiency, coherence, impact and sustainability. It is not a set of indicators, but it guides which dimensions to evaluate. When to use it: in evaluations of public or cooperation programs that require comprehensive evaluative judgment.
  • ISO 37120/37122 (Cities): Sets of urban indicators (services, quality of life, open data). When to use it: in territorial projects that must dialogue with local governments and be compared between cities.
  • National frameworks (e.g.: SDG dashboards, sectoral guidelines, government M&E systems): They adapt global standards to the regulatory and statistical context of each country. When to use them: when you report to public entities or need official and locally comparable series.

Practical hint: Combine 1-2 “anchor” frameworks (e.g. SDG + IRIS+) and complement with a specific contextual layer of your intervention.

The trade-off when choosing indicators: comparability vs. relevance

Choosing indicators just because they fit perfectly into an international index can leave out key nuances of the territory and population. Going to the other extreme - very particular indicators - makes it difficult to compare, attract resources and learn from others. That's the trade-off.

Two opposite risks:

  • Too standardized: they are comparable, but they may not capture the significant change in your community, nor the real mechanism of your intervention.
  • Too particular: They describe your case very well, but they cannot be contrasted or replicated. You lose traceability and dialogue with recognized frameworks.

How ​​to decide wisely:

  1. Objective: decide what the evidence is for. Scale, adjust operations, prioritize resources or be accountable?
  2. Anchor with 1-2 frames: Select recognized indexes that fit your topic/sector.
  3. Adjust to the context: adapt definitions, disaggregations (age, gender, rurality) and thresholds so that the indicator “reads” your reality.
  4. Define the line of causality: map outputs → results → impacts onto your theory of change (roadmap to changing the lives of others).
  5. Validate measurement and cost: make sure the data is measurable with quality at a reasonable cost.
  6. Test and correct: pilot 1-2 cycles and refine technical sheets (source, periodicity, formula, responsible).

Balances standardization and relevance: comparable enough to dialogue, contextual enough to decide well.

How we choose indicators in Resolves

Our mentality is “decisions first.” We select indicators that are truly useful, and then map them to recognized indices for comparability.

This is how we work:

  1. Strategic question: we define the decision that the team will make with the evidence (improve, scale, close, redesign).
  2. Clear theory of change: we align the indicators to the causal path (outputs, results, impacts).
  3. Framework exploration: we review SDG, IRIS+, GRI and national frameworks of the project country, we choose the most relevant ones.
  4. Custom adaptation: we ground definitions, disaggregations and goals to the context (population, territory, data restrictions).
  5. Feasibility and quality: we evaluate available sources (surveys, records, systems), operational load and reliability.
  6. Technical data sheet and traceability: we document formula, unit, frequency, those responsible and data route, for audit and continuity.
  7. Pilot and continuous improvement: we test, adjust and only then close the final set.

Result: a set of indicators that aligns with recognized indices and, at the same time, is optimal for management and impact evaluation.

Practical tips for using indicators without losing context

  • Less is more: prioritize 8-15 well-measured indicators over 40 superficial ones.
  • Disaggregates the key: defines cuts by relevant subpopulations; That's where the impact usually “appears.”
  • Includes quality and use of the service: Don't stop at just coverage.
  • Differentiate levels: Label each indicator as output, result or impact to read the entire movie.
  • Ethical data plan: consent, privacy and return of results to participants.
  • Governance: assigns managers and calendars; Without owners, the indicators go cold.

Conclusion

Impact indices give you common language, discipline and credibility. But no framework is a substitute for judgment about your context. The art is in the balance: align with recognized references and adapt what is necessary so that your indicators guide real decisions.
