Expert competence
Competence is the demonstrated ability to apply knowledge and skill to a defined task in a given context. Qualifications, titles and years of experience are proxies for it, and in technical assistance they are often self-declared and lightly checked. This page sets out how competence is described, what evidence supports a claim, how weak verification turns into delivery risk, and what the institutions that select and supervise experts need to see.

The short answer.
Expert competence is the demonstrated ability to apply knowledge and skill to a defined task in a given context. Qualifications, titles and years of experience are proxies for it, often self-declared and lightly checked in technical assistance, so competence claims need verifiable evidence such as registrations, completion reports and references.

Expert competence: how the risk develops.
Skills, evidence and relevant experience. The dossier below sets out how the risk develops, what is measured, where the data come from, how it is modelled and who decides.
Credentials are proxies
A degree or professional title shows that training was completed at some point. It does not show performance on a comparable task, in a comparable institution, under comparable constraints. Evidence of applied work carries more weight than the credential alone.
Context limits transfer
Experience gained in one legal system, sector or language does not transfer automatically. Procurement law, public finance rules and safeguard regimes differ, and an expert strong in one setting can mislead in another.
Unverified claims compound
Curricula vitae are reused across proposals, and a claimed role on a past project is rarely checked against the project's own records. Key experts named at award are sometimes replaced after contract signature by less qualified substitutes.
Competence gaps cascade
An error in a feasibility study or a specification passes into tender documents, then into works contracts and safeguard plans. By the time it surfaces, correcting it means variations, delays and sometimes harm to affected people.
Terms used on this page.
Each term as this page uses it. Where a standard-setting body defines the term, the wording follows that body.
| Term | Definition |
|---|---|
| Key expert | An expert named in a winning proposal whose qualifications were scored in the award. |
| Substitution | Replacement of a key expert after contract award, which procurement rules usually allow only with equivalent qualifications. |
| Competence framework | A structured description of the skills and knowledge a role requires, such as ESCO. |
What is measured, and how well.
Each indicator carries its unit, its cadence, the kind of source behind it and the evidence label a value would carry. No values are shown: a programme supplies them under its own authority.
| Indicator | Unit | Cadence | Source type | Label |
|---|---|---|---|---|
| Competence claims supported by verifiable evidence | percent of claims | per engagement | Reference checks, project records, registers | REPORTED |
| Professional registrations confirmed with the issuing body | percent of registrations claimed | per engagement | Professional and regulatory registers | OFFICIAL |
| Key expert substitutions after contract award | count per contract | per contract | Procurement and contract records | OFFICIAL |
| References checked before engagement | percent of engagements | quarterly | Engagement records | REPORTED |
| Prior roles confirmed against completion reports or published activity data | percent of roles claimed | per engagement | Completion reports, IATI records | REPORTED |
| Performance evaluations completed at assignment end | percent of assignments | per assignment | Client and supervisor evaluations | REPORTED |
| Language and context requirements met | percent of requirements | per engagement | Terms of reference against evidence | DECLARED |
From sources to decisions.
The topic as a computational graph: named sources feed the methods, an evidence review gates the outputs, and the decisions stay with the authorities that hold them.
Fig. 02Nodes carry their type, two metric rows and a state; connectors show what feeds what; dashed frames name the owners; the timeline is the cadence. Design of the pipeline, not a record of a run.
Where the evidence comes from.
Named public datasets and institutional records, each with its licence class. Sources by agreement are used only under their terms and never republished.
| Source | What it gives | Licence class |
|---|---|---|
| ESCO classification (European Commission) | Multilingual taxonomy of occupations, skills and competences for describing expert profiles | Free and open, attribution under EU reuse policy |
| International Standard Classification of Occupations (ILO) | Occupational groups for consistent description of roles across countries | Free, attribution |
| National professional and regulatory registers | Licensure and registration of engineers, accountants, lawyers and health professionals | Public registers, terms per regulator |
| World Bank and regional development bank completion reports | Project records against which claimed past roles and outputs can be checked | Public documents under each bank's access to information policy |
| IATI Datastore | Participating organisations and documents of past activities | Open, licence declared per publisher |
| Procurement contract records on national portals | Named key experts, substitutions and contract variations | Public records, terms per procurement authority |
Who decides, and what the evidence serves.
Nexus Agency prepares evidence. The decisions below are taken by the authorities named, under their own rules, and never by the platform.
| Who decides | The question | Evidence this page serves |
|---|---|---|
| Client evaluation committee | Whether an expert's evidence meets the competence the terms of reference require | Competence profile with each claim labelled verified, declared or unverified |
| Funding agency procurement reviewer | Whether to give no objection to an award or a key expert substitution | Evidence for the proposed and substitute expert against the same criteria |
| Professional regulatory body | Whether a person is licensed to perform a reserved professional act in the jurisdiction | Registration status from the register, not from the curriculum vitae |
| Supervising project manager | Whether performance on the assignment matches the competence claimed | Deliverable acceptance records and structured performance evaluation |

- Substitution rules with equivalent-competence tests
What a reviewer needs to know.
- What exactly does the task require: which methods, tools, contexts and languages?
- What evidence shows that this person has applied those methods successfully?
- Who supervised or reviewed that work and can speak to it?
- Where are the gaps, and can supervision cover them?
Proxies mislead.
Titles and affiliations say little about whether someone can calibrate a hydrological model in a data-poor basin or design a privacy-preserving survey. Reliance on proxies tends to favour people already well connected, and it misses practitioners whose competence was built in operations rather than in publications.
Competence is also contextual. An expert in flood frequency analysis in one climate may need support to work in another; a strong software engineer may lack the domain knowledge to judge whether a model's output is plausible. Good matching reads the evidence against the specific task and names the support needed.
How competence is assessed.
- 01
Work products
Publications, models, code, datasets or project records the candidate can show and explain.
- 02
References
Named referees who supervised or reviewed the work, contacted only with consent.
- 03
Scoped tasks
Where the work needs it, a short exercise matched to the assignment and assessed against stated criteria.
- 04
Frameworks
Fields and methods are read against the STEM Commons, through systems engineering and decision analysis under uncertainty among others. No framework captures every skill, so reviewer judgement is recorded with its reasons.
