Quick answer
Quality assurance standards, primarily ISO 9001, are management system certifications that contracting authorities may require as evidence of technical and professional ability, confirming that a supplier has a documented, audited system for consistently managing quality across its operations and service delivery.
ISO 9001 is the internationally recognised standard for quality management systems (QMS). In public procurement across Europe, it is frequently specified as a minimum technical and professional ability criterion because it provides an independent, third-party-audited assurance that a supplier has systematic processes for managing the quality of its work. Buyers cannot independently audit every supplier's internal processes, so certification to a recognised standard acts as a credible proxy.
What are Quality Assurance Standards (ISO 9001)?
Article 62 of Directive 2014/24/EU addresses quality assurance and environmental management standards in public procurement. Where a contracting authority requires a supplier to hold certification to a quality assurance standard, it must accept ISO 9001 or equivalent certification as evidence of compliance. The authority may not insist on a specific certifying body or a specific national variant of the standard.
ISO 9001 sets requirements for a quality management system covering:
Customer focus and leadership. The organisation must define quality objectives linked to customer requirements and ensure top management demonstrates commitment to the QMS.
Risk-based thinking and process management. Processes must be identified, documented, and controlled. Risks and opportunities affecting quality must be assessed and addressed.
Operational controls. Requirements for planning, design and development (where applicable), production and service delivery, and control of externally provided products and services (supply chain management).
Performance evaluation and improvement. Measurement, monitoring, internal audits, management reviews, and systematic continual improvement of the QMS.
ISO 9001 is published by the International Organization for Standardization and is revised periodically; the current version is ISO 9001:2015. Certification is granted by accredited certification bodies and renewed through regular surveillance audits.
Contracting authorities must also accept equivalent quality assurance schemes, such as sector-specific quality standards (for example, AS9100 for aerospace or ISO 13485 for medical devices), or other evidence of equivalent quality management capability, if a supplier can demonstrate it does not have access to ISO 9001 certification within the required timescale or for justified reasons. In practice, for most buyers, ISO 9001 is the clearest and most widely accepted evidence.
Why ISO 9001 Matters for Bidders
ISO 9001 certification is a gate criterion in many European public procurements, particularly for service contracts above a certain value. A supplier without certification faces the choice of obtaining it (a process taking several months at minimum), demonstrating equivalent capability by other means, or being excluded from those competitions. For suppliers targeting significant volume in public markets, certification is almost always worthwhile.
Beyond selection criteria, ISO 9001 has practical benefits: it disciplines internal processes, reduces errors and rework, and provides a documented evidence base that is also useful in quality submissions at the award stage. The investment in certification typically delivers returns across both public and private sector business.
Example
An Austrian healthcare technology firm bids for a national patient records system contract. The selection criteria require ISO 9001:2015 certification covering software development and implementation services. The firm holds certification for its core software products but its implementation services division has not been included in the scope of its certificate. The certifying body confirms that extending the scope of the certificate to include implementation services can be completed within three months. The firm requests and obtains a scope extension before the bid submission deadline and includes the updated certificate in its selection questionnaire (SQ).
Frequently Asked Questions
What is the difference between ISO 9001 and ISO 27001?
ISO 9001 covers general quality management. ISO 27001 covers information security management. Both are sometimes required in IT and data-handling contracts, either as separate selection criteria or combined. A supplier may hold both certifications, which cover different aspects of operational risk.
Can a supplier use a parent company's ISO 9001 certificate?
Generally only if the parent's certificate explicitly covers the subsidiary's activities and geographic location. Certificates are scoped to specific sites, processes, and activities. A certificate issued to a parent holding company does not automatically cover an operating subsidiary unless that subsidiary is named within the certificate scope.
Does ISO 9001 certification expire?
No, it does not expire, but it requires ongoing maintenance through annual surveillance audits and a full recertification audit every three years. A certificate that has lapsed because surveillance audits were not completed is no longer valid and will not satisfy a procurement requirement.

Technical and Professional Ability
Technical and professional ability is the selection criterion category under which a contracting authority assesses a supplier's proven delivery capability, including past contract references, key staff qualifications, equipment, quality certifications, and subcontracting capacity, to confirm it can perform the specific contract being procured.
ViewSelection Criteria
Selection criteria are the minimum standards of suitability that a contracting authority applies to determine whether a supplier is capable of performing a contract, covering economic and financial standing, technical ability, and legal eligibility before any evaluation of the tender itself begins.
ViewEnvironmental Management Standards (ISO 14001)
Environmental management standards, primarily ISO 14001 and the EU Eco-Management and Audit Scheme (EMAS), are system certifications that contracting authorities may require as evidence of technical and professional ability, confirming that a supplier has a structured approach to identifying, managing, and reducing its environmental impacts.
ViewRelevant Experience Requirement
A relevant experience requirement is a technical and professional ability criterion under which a contracting authority requires suppliers to demonstrate a specified number of comparable past contracts within a defined reference period, typically the last three to five years, in order to prove proven delivery capability before being permitted to bid.
ViewPre-Qualification Questionnaire (PQQ)
A Pre-Qualification Questionnaire (PQQ) is a structured document used by contracting authorities in restricted and other multi-stage procedures to assess suppliers' suitability before inviting them to tender, covering exclusion grounds, economic and financial standing, and technical and professional ability to create a shortlist of qualified bidders.
