Accessibility Indicator System

DIEGO FERRE 1 1

Spaces for everyone,
without exception

The AIS certification is the most comprehensive international accessibility standard globally, backed by the ARS Foundation. It evaluates and accredits the accessibility conditions of physical spaces, services, websites, and products, recognizing up to five levels of excellence through a star system.
‍
With more than 4,000 certificates issued in 32 countries and clients such as Google, Coca-Cola, Real Madrid, and BBVA, AIS has become the benchmark for organizations that want to demonstrate their commitment to inclusion in an objective and verifiable way.

How does it work?

AIS evaluates accessibility conditions through an authorized advisor, who performs an assessment and supports the improvement process. Once the criteria are met, the ARS Foundation issues the certificate with a level of 1 to 5 stars based on the degree of excellence achieved, which is then published in the AIS Public Registry.

Investment

The cost varies depending on the type of asset (physical space, website, or product) and its complexity. At Leaf, we support the entire process as authorized advisors, helping you plan improvements efficiently to minimize investment.

Who is it for?

Any organization that wants to certify its commitment to accessibility: shopping centers, office buildings, hospitals, hotels, educational institutions, airports, and companies with a digital presence. It is especially relevant for organizations with active ESG, DEI, or CSR policies.

Requirements

Comply with the accessibility criteria defined by AIS according to the type of asset, using the current regulations in each country as a reference. The process begins with an assessment and concludes when the asset reaches a minimum level of 1 star.

Each star reflects a higher degree of excellence in accessibility. To obtain 1 star, minimum criteria must be met, while higher levels require more comprehensive improvements. Investment and timelines depend on the type of asset, its complexity, and its current conditions.

Can a space that is already built and in operation be certified?

What is Leaf's role during this AIS certification process?
