NEW YORK — Folks on Sesame Street have a way of making everyone feel accepted.

That certainly goes for Julia, a Muppet youngster with blazing red hair, bright green eyes — and autism. Rather than being treated like an outsider, which too often is the plight of kids on the spectrum, Julia is one of the gang.

On this friendliest of streets (actually Studio J at New York’s Kaufman Astoria Studios, where “Sesame Street” lives) Julia is about to play a game with Oscar, Abby and Grover. In this scene being taped for airing next season, these Muppet chums have been challenged to spot objects shaped like squares, circles or triangles.

“You’re lucky,” says Abby to Grover. “You have Julia on your team, and she is really good at finding shapes!”

With that, they skedaddle, an exit that calls for the six Muppeteers squatted out of sight below them to scramble accordingly. Joining her pals, Julia (performed by Stacey Gordon) takes off hunting.

For more than a year, Julia has existed in print and digital illustrations as the centerpiece of a multifaceted initiative by Sesame Workshop called “Sesame Street and Autism: See Amazing in All Children.”

She has been the subject of a storybook released along with videos, e-books, an app and website. The goal is to promote a better understanding of what the Autism Speaks advocacy group describes as “a range of conditions characterized by challenges with social skills, repetitive behaviors, speech and nonverbal communication, as well as by unique strengths and differences.”

But now Julia has been brought to life in fine Muppet fettle. She makes her TV debut on “Sesame Street” in the “Meet Julia” episode airing April 10 on both PBS and HBO. Additional videos featuring Julia will be available online.

Developing Julia and all the other components of this campaign has required years of consultation with organizations, experts and families within the autism community, according to Jeanette Betancourt, Sesame Workshop’s senior vice president of U.S. social impact.

“In the U.S., one in 68 children is diagnosed with autism spectrum disorder,” she says. “We wanted to promote a better understanding and reduce the stigma often found around these children. We’re modeling the way both children and adults can look at autism from a strength-based perspective: finding things that all children share.”

Julia is at the heart of this effort. But while she represents the full range of children on the spectrum, she isn’t meant to typify each one of them: “Just as we look at all children as being unique, we should do the same thing when we’re looking at children with autism,” Betancourt says.
