Effectiveness Accreditation 2027-2029
Key information
The IPA is dedicated to helping UK agencies and their clients succeed by providing practical support through initiatives like CPD Gold, specialised training, and thought-provoking leadership events. With a clear focus on what drives measurable success, the IPA is uniquely equipped to guide agencies in building a culture of effectiveness, backed by cutting-edge research, valuable events, and hands-on resources.
UK agencies are globally recognised as leaders in effectiveness, with their strong presence in the IPA Effectiveness Awards as clear evidence of this standard. Building an effectiveness-driven culture is essential not only for producing award-winning work but also for achieving the powerful results that clients seek. The IPA commitment to fostering this culture empowers agencies to lead, deliver, and set the global benchmark for impactful, results-focused work.
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.
