The entire staff at the theme park in Langhorne, Pennsylvania, has completed autism sensitivity and awareness training.
The completion designates Sesame Place as a Certified Autism Center.
"As the first theme park in the world to complete the training and become a CAC, Sesame Place is better equipped to offer families inclusive activities for children with autism and other special needs," Sesame Place park president Cathy Valeriano said in a statement.
The certification comes at the start of National Autism Awareness Month.
Sesame Place opens for its 38th season on April 28.
