The Autism Research Institute’s strong financial health and commitment to accountability and transparency have once again earned it Charity Navigator’s highest rating (“4 stars”) and Candid GuideStar’s highest rating (“Platinum”).

In a letter to the organization, Michael Thatcher, president and CEO of Charity Navigator congratulated ARI for demonstrating strong financial health and commitment to accountability and transparency. “Based on the most recent information available, we have issued a new rating for your organization. We are proud to announce Autism Research Institute has earned our fifth consecutive 4-star rating. This is our highest possible rating and indicates that your organization adheres to sector best practices and executes its mission in a financially efficient way. Attaining a 4-star rating verifies that Autism Research Institute exceeds industry standards and outperforms most charities in your area of work. Only 17% of the charities we evaluate have received at least 5 consecutive 4-star evaluations, indicating that Autism Research Institute outperforms most other charities in America. This exceptional designation from Charity Navigator sets Autism Research Institute apart from its peers and demonstrates to the public its trustworthiness.”

 “It’s important that our donors continue to trust that we’re using their gifts wisely in order to accomplish our mission to support the health and well-being of people affected by autism through innovative, impactful research and education,” said Stephen M. Edelson, Ph.D., Executive Director of ARI.  “These ratings demonstrate our transparency, good governance, and financial accountability.”

Established in 1967 by psychologist and renowned father of modern autism research Dr. Bernard Rimland, ARI continues to pioneer in research, outreach, and cooperative efforts with other organizations worldwide. ARI advocates for the rights of people with ASD, and operates without funding from special-interest groups. Visit us online at
