Consultants' Qualifications Selection (CQS)

Consultants' Qualifications Selection (CQS) is a streamlined method used by multilateral development banks for small or straightforward consulting assignments, where the bank selects the best-qualified firm on the basis of its track record and relevant experience alone, without requesting full competitive technical and financial proposals.

What is Consultants' Qualifications Selection?

CQS shortens the selection process by eliminating the full proposal stage. Instead of issuing a Request for Proposals and evaluating detailed technical and financial submissions, the bank or its borrower invites a shortlist of firms, reviews their qualifications, selects the most appropriate one, and negotiates the scope and fee directly. The selection criteria focus on the firm's relevant experience in similar assignments, the calibre of key staff available, and demonstrated capacity to complete the work.

The method is reserved for assignments where the scope is well-defined, the risks are low, and the contract value falls below the threshold at which the more competitive qcbs or qbs methods are warranted. The World Bank applies CQS for consulting contracts generally below USD 300,000, though thresholds vary by country and project. ADB uses CQS under the same logic: straightforward assignments where a qualifications review is sufficient to identify a capable firm.

Because CQS bypasses the full proposal cycle, the Terms of Reference (tor) must still be clear enough to allow the firm to price the work during negotiation. The bank negotiates with the first-ranked firm and, if agreement is not reached, moves to the next.

Why CQS matters for bidders

CQS is often underestimated by consulting firms that focus only on large QCBS competitions. For a firm building a track record in a new region or sector, CQS assignments provide a lower-competition entry point into development-bank-financed work, because the decision turns almost entirely on the depth of the firm's relevant experience and the availability of suitably credentialled staff. Maintaining a detailed, well-organised qualifications profile covering past assignments by sector, geography, client type, and contract value directly improves a firm's standing in CQS shortlisting. Firms that win CQS assignments build the track record that later strengthens their qcbs proposals.

Example

A World Bank-financed urban water project in Indonesia may require a short advisory assignment to review tariff-setting methodology. The value of the assignment falls below the QCBS threshold, so the implementing agency uses CQS, invites three or four firms with demonstrated tariff advisory experience in Southeast Asia, assesses their qualifications, and negotiates terms with the highest-ranked firm. No full proposal is required, and the process can be completed in weeks rather than months.

Frequently Asked Questions

How does CQS differ from QCBS?

Under qcbs, competing firms submit full technical and financial proposals that are scored and combined with a published weighting. Under CQS, the bank shortlists and ranks firms on qualifications alone and negotiates directly with the top-ranked firm, without a competitive proposal submission.

What contract values typically use CQS?

The World Bank applies CQS for consulting assignments generally below USD 300,000. The exact threshold varies by borrower country and project, and individual loan agreements may set lower prior-review thresholds that override the default.

Does CQS mean there is no competition at all?

There is still a shortlisting stage in which multiple firms are compared on qualifications, so it is not single-source selection. However, firms do not submit competing proposals, and the awarded contract is negotiated rather than determined by scored evaluation.
