We are the European Union’s (EU) external auditor.

The ECA’s College is made up of the individual Members assigned by each Member State and is supported by some 900 staff of all EU nationalities.

Our mission

Through our independent, professional and impactful audit work, our mission is to assess the economy, effectiveness, efficiency, legality and regularity of EU action in order to improve accountability, transparency and financial management, thereby enhancing citizens’ trust and responding effectively to current and future challenges facing the EU.

Our vision

We aim to be at the forefront of the public audit profession, and to contribute to a more resilient and sustainable EU that upholds the values on which it is based.

We base our work on the following values:

  • Independence

    We carry out our work free from any influence that may compromise or be seen to compromise our professional judgement.

  • Integrity

    We act honestly, reliably and solely in the EU public’s interest, and aim to lead by example in both our professional work and the way in which we manage our institution.

  • Objectivity

    We are impartial and unbiased, and base our audit conclusions on sufficient relevant and reliable evidence.

  • Transparency

    We communicate our findings in clear, comprehensive and accessible reports, which are published in all EU languages and respect confidentiality and data protection requirements.

  • Professionalism

    In line with the international auditing standards, we acquire, develop and maintain the highest levels of knowledge, expertise and skill in relation to both the public audit profession, and EU financial and policy management.
