The IPA Effectiveness Accreditation is an endorsement that your agency culture is dedicated to business effectiveness. It can turn what you already do into a competitive advantage for attracting clients and talent, as well as providing an incentive to maintain existing high standards.
Why Effectiveness Accreditation matters
Effectiveness Accreditation 2027-2029
Key information
Launched in 2021, the IPA Effectiveness Accreditation is a mark of distinction for agencies in an increasingly competitive market. It recognises agencies that understand marketing as a strategic investment with measurable returns, not just a cost. Agencies with the IPA Effectiveness Accreditation have proven they have the tools, insights and framework to make effectiveness a core part of their culture, which is delivering value to their clients. Once achieved, the Accreditation will last for two years. Agencies will then have to reapply after two years to retain their status.
