The UNEG Norms and Standards for Evaluation

What the instrument is

The United Nations Evaluation Group — the professional network of the evaluation offices of UN agencies, funds and programmes — maintains one foundational document for the whole system: the Norms and Standards for Evaluation. The originals were adopted in 2005; a full revision was adopted unanimously at the UNEG Annual General Meeting in April 2016, and the 2016 text is the version in force today [1].

The document’s ambition is narrow and useful: not to prescribe methods, but to define the conditions under which an evaluation deserves to be believed and used. It does this in two layers. The norms say what evaluation in the UN system must be — independent, impartial, credible, ethical, transparent, useful. The standards say what an evaluation function must do — how it is institutionally situated, managed, staffed and conducted — for those properties to hold in practice. Reading the instrument as a single list flattens it; the two layers answer different questions and are used by different people. A programme officer citing “independence” is invoking a norm; the evaluation office defending its reporting line to the governing body is implementing a standard.

The general norms

The 2016 revision distinguishes general norms, to be upheld in the conduct of any evaluation, from institutional norms, to be reflected in the management and governance of evaluation functions [1]. The general norms, by their published titles, are:

Internationally agreed principles, goals and targets — evaluation in the UN system is anchored to the commitments member states have actually made, not to free-floating notions of merit.
Utility — evaluation exists to inform decisions; an unused evaluation has failed regardless of its rigour.
Credibility — the grounds a reader has for believing findings: sound methods, adequate evidence, competent people.
Independence — the evaluation function and its evaluators must be free of undue influence from those who design, implement or fund what is evaluated.
Impartiality — the absence of bias at every stage: scoping, evidence gathering, analysis and reporting.
Ethics — evaluations must respect the rights and dignity of participants and do no harm in the gathering and handling of evidence.
Transparency — open terms of reference, disclosed methods and limitations, and accessible reports.
Human rights and gender equality — evaluation must be informed by, and interrogate performance against, the UN’s universal commitments.
National evaluation capacities — evaluation practice should strengthen, not substitute for, countries’ own evaluation systems.
Professionalism — evaluation is skilled work; the norm anchors competencies, ethical conduct and peer accountability.

The set is not closed. In February 2025, UNEG approved an additional norm and standard on environmental and social impacts, extending the instrument to cover the environmental consequences of the interventions evaluated and of evaluation practice itself [1]. If you cite the Norms and Standards in a policy document, cite the 2016 edition and check the UNEG site for subsequently approved additions — the instrument is maintained, not frozen.

Alongside the general norms sit four institutional norms addressed not to individual evaluations but to organisations: they concern the enabling environment for evaluation, the existence of an evaluation policy, clear responsibility for the evaluation function, and arrangements for the use and follow-up of findings [1].

The standards layer

The standards translate the norms into observable practice. They cover the ground an assessor of an evaluation function — as opposed to a single report — would examine: the institutional framework in which evaluation sits; the management of the evaluation function; the competencies and ethics of the people doing the work; the conduct of individual evaluations across their lifecycle; and the quality of what is produced [1]. The direction of travel matters: each standard exists because some norm is empty without it. Independence (a norm) is delivered by structural arrangements — reporting lines, budget protection, unedited publication rights — that are standards. Professionalism (a norm) is delivered through competency frameworks and recruitment practice. When an organisation claims conformity with the norms but cannot point to the corresponding standards in its own arrangements, the claim is decorative.

Figure 1. The two-layer architecture: norms define what evaluation must be; standards define how an evaluation function delivers it. Companion instruments — the Ethical Guidelines (2020) and the Quality Checklist (2010) — operationalise specific norms at the level of individual conduct and individual reports.Structure follows UNEG, Norms and Standards for Evaluation (2016).

The companion instruments

Two UNEG documents do the operational work the Norms and Standards deliberately leave open.

The UNEG Ethical Guidelines for Evaluation cash out the ethics norm at the level of individual conduct. First issued in 2008 and revised in 2020, they bind everyone involved in an evaluation — commissioners and managers as well as evaluators — and cover integrity, accountability, respect and beneficence in the treatment of participants and evidence [2]. If your organisation’s evaluations touch human participants at all, this is the document to put in every consultant contract; our page on ethics and consent covers the field-level practice.

The UNEG Quality Checklist for Evaluation Reports, approved in 2010, operationalises the credibility and transparency norms at the level of the finished product: a structured instrument for reviewing whether a report describes its object and methods, supports findings with evidence, and draws conclusions and recommendations that follow from them [3]. It is the backbone of many organisations’ report review grids — treated in depth on evaluation quality assessment.

Using the Norms and Standards outside the UN

Nothing restricts the instrument to UN entities, and adoption beyond the system is common: NGOs writing their first evaluation policy, government M&E units seeking an external reference, and philanthropic funders standardising commissioning practice all borrow it. What declared conformity buys is real but limited:

A shared vocabulary. “Independence”, “impartiality” and “credibility” acquire agreed, citable meanings, which shortens arguments about terms of reference and reviewer comments.
A design template. The institutional norms and the standards amount to a checklist for setting up an evaluation function: policy, reporting line, budget, competencies, disclosure practice.
An external anchor for disputes. When an evaluation is challenged — findings suppressed, scope narrowed mid-stream — pointing to a published international norm is stronger than pointing to internal preference.

Be equally honest about what it does not buy. There is no conformity assessment, no certification and no enforcement: an organisation can claim adherence while violating the independence norm daily, and no external body will say otherwise. Conformity claims are only as good as the internal arrangements — and ideally the published evidence, such as disclosed reports and management responses — behind them.

Relation to the OECD DAC Quality Standards

The UNEG instrument’s closest counterpart is the OECD DAC’s Quality Standards for Development Evaluation (2010), the bilateral donor community’s agreed process standard, endorsed by the DAC in February 2010 [4]. They are complementary rather than competing: the UNEG document is strongest on what evaluation is and how a function is governed; the DAC document is organised around the process of a single evaluation, from purpose and planning through implementation, reporting and follow-up [4]. Note the standing confusion of names: the DAC Quality Standards are a different instrument from the DAC evaluation criteria (relevance, coherence and the rest). This site does not restate the criteria — see the OECD-DAC evaluation criteria explainer on monival.com for those.

Table 1. What each instrument governs, and where a non-UN organisation would reach for it.

A national evaluation policy will typically cite two or three of these at once — UNEG for the norms layer, the DAC standards for process, and sometimes a regional instrument such as the African Evaluation Principles for context. That is not redundancy; it is the layers doing different jobs.

What to take from this page

Treat the UNEG Norms and Standards as the system’s constitution rather than its procedures manual: short, principled, and dependent on subsidiary instruments for enforcement of anything. When you adopt it, adopt the layer structure too — write your evaluation policy so that every principle you claim is traceable to an arrangement someone could inspect. And when you assess an evaluation or an evaluation function against it, say which layer you are assessing: a fine report can come out of a captured function, and an independent function can still produce weak reports. The instruments for judging the reports themselves are the subject of evaluation quality assessment.
