UN and IO consultancy contracts: how individual contractor agreements actually work

A large share of real hiring across the UN system, the development banks and the INGOs never touches a graded staff post at all — it moves through an individual consultancy: a fixed-scope contract against specific terms of reference (ToR) rather than an ongoing job. For many candidates, especially early in a career or moving between organizations, a consultancy is the fastest door in, and for the organizations themselves it's how a large amount of technical, surge and short-cycle work actually gets delivered.

This guide explains what a consultancy contract actually is, how it differs from staff employment, where the terms of reference are posted, how selection works, and what it takes to win a first one. For how staff hiring works by contrast, see how to get a job at the UN; for the early-career routes that often lead through a consultancy, see the early-career routes guide.

What a consultancy contract actually is

A consultancy is an agreement to deliver a defined piece of work — a report, a review, a set of trainings, coverage of a specific function for a fixed period — against terms of reference that spell out deliverables, a timeline and a fee, rather than an open-ended job description. The contract is with the organization directly, not through a staffing agency, and the individual is engaged as a non-staff contractor: no letter of appointment, no staff ID in the same category as regular personnel, and none of the entitlements that come with a staff contract. It is a real, common and entirely legitimate way to work across this sector — not a workaround.

Contract types: IC, SSA, PSA, LICA — same idea, different name

Every organization uses its own label for essentially the same instrument, which is why the terminology across job boards looks more fragmented than it is:

• Individual Contractor Agreement (ICA) — UNDP, UNOPS and several UN funds and programmes' standard vehicle for engaging individuals against a ToR, usually paid on a lump-sum or deliverable basis.
• Special Service Agreement (SSA) — used across much of the UN common system (WHO, FAO and others) for short-term, deliverable-based individual engagements.
• Personal Services Agreement/Contract (PSA/PSC) — common at UNFPA, UNHCR and a number of agencies for longer-running individual functions that sit closer to a role than a single deliverable.
• Local/International Individual Contractor Agreement (LICA) — UNOPS's naming for the same instrument, split by whether the contractor is recruited locally or internationally.
• Short-term/extended-term consultant (STC/ETC) — the World Bank Group and regional development banks' equivalent, covered in the MDB recruitment guide.

The exact name, ceiling on renewals and administrative rules differ by organization and are set out in that organization's own contractual policy — the vacancy notice or ToR is the authoritative source for a given engagement, not a general rule of thumb.

Consultant vs staff: what actually changes

The practical differences are consistent across almost every organization that uses both tracks:

• No staff benefits. No post adjustment, no dependency allowances, no pension-fund participation, and typically no organization-paid health insurance — consultants are generally expected to arrange their own coverage and are paid a fee, not a salary built on the ICSC scale.
• Fee, not grade. Consultancy pay is set per ToR — often benchmarked loosely against the equivalent staff grade for the seniority of the work — rather than placed on a step within the common system scale described in the ICSC salary guide.
• Fixed scope, fixed end date. A consultancy exists to deliver specific outputs by a specific date; it does not carry the expectation of renewal that a staff post's performance cycle does, even where consultancies are in practice renewed repeatedly.
• Own tax and social security. Consultants are usually responsible for their own tax filing and social security contributions in their country of residence — organizations generally do not withhold or pay these on a contractor's behalf, unlike for staff in many duty stations.
• Caps on consecutive engagement. Most organizations cap how long, or how many cumulative days, an individual can be engaged as a consultant before a break or a conversion to staff is required — the specific cap is set by each organization's own policy and changes over time, so check the current rule rather than a past contract's terms.

Where consultancy ToRs are posted

Consultancies are advertised through the same channels as staff vacancies — an organization's careers site, UNjobs-style aggregators and this board among them — but they move faster and with a shorter shelf life than a staff post, and a meaningful share never get advertised publicly at all: a programme manager who already knows a specialist's work simply issues a ToR to them directly. That's why a consultancy career, more than a staff career, runs on network as much as on job boards — see the early-career guide for how a first consultancy tends to open the door to the next one.

How a consultancy is actually selected

1. A hiring manager or technical unit drafts the ToR: objectives, deliverables, timeline and required qualifications.
2. The ToR is advertised (or, informally, circulated within a known network) and applications are collected — usually a CV plus a short technical/financial proposal or cover note rather than a full application form.
3. A light technical review against the ToR's stated qualifications — there is rarely a formal panel interview process as structured as staff recruitment, though a call or short interview is common for higher-value engagements.
4. Reference or past-performance checks, especially for repeat engagements with the same organization or unit.
5. Contract issuance directly against the ToR, with payment tied to accepted deliverables rather than a monthly salary run.

The repeat-hire pattern and its limits

Because consultancy hiring is faster and less procedurally heavy than staff recruitment, it's common for the same individual to be re-engaged by the same unit across several consecutive ToRs — in effect functioning like a role, even though each contract is legally a separate, fixed-scope engagement. Organizations are increasingly attentive to this pattern (it can create legal and budgetary exposure if a "consultant" is functioning as de facto staff), which is behind the caps on consecutive engagement noted above. Treat a long run of consultancies with one organization as a strong signal to watch for the next staff vacancy in that unit, not as a substitute for one.

How to win your first consultancy

• Lead with deliverables, not duties. A ToR is scored against what you can produce by when — name outputs you've delivered (reports, evaluations, curricula, systems) rather than responsibilities you held.
• Price it realistically. Where a proposal asks for a daily or lump-sum fee, benchmark against the seniority level implied by the ToR rather than under- or over-pricing — both read as a lack of familiarity with the sector.
• Build the network before you need it. Because many ToRs circulate informally, being known to a technical unit — through prior work, a conference, a shared professional network — matters as much as a strong application to a posted one.
• Treat every consultancy as a reference for the next. Deliverables completed on time and well are what turn a first short engagement into a repeat client relationship, which is how most consultancy careers in this sector actually compound.
• Know your own tax and insurance position. Understand what a consultancy fee needs to cover — tax, social security, health insurance — before comparing it directly to a staff salary figure; the headline fee and the staff salary for equivalent work are not the same number once those are accounted for.

A consultancy is not a lesser door into this sector — it's often the fastest one, and for many specialists it's a durable way to work across several organizations rather than a single employer.
