Yes, it’s true that some of the events in “Abbott Elementary” really happened.
Brunson said,
“Abbott Elementary” is set in Philadelphia and is “loosely based” on my mother’s experience as a public school teacher in Philadelphia; “she simply had many anecdotes during her 40 years serving the Philadelphia school system,”
Brunson is also acquainted with the Philadelphia public school system, and she drew on her personal experiences there to shape the show’s narrative.
