Shankerdas commented, "When I first heard about Ms. Marvel being this brown teenage girl, I thought it was really cool that we’re finally represented. On top of that, we were represented in the Marvel Universe, and I thought that was really cool, because it’s a big company."

The school's principal is Thomas Macagnano. Core members of the school's administration include the assistant principal.

The high school that Marvel superhero Ms. Marvel goes to is named "Coles Academic High School," which is loosely based on McNair Academic.
