Graduates of a Southern California high school received a head-scratching surprise on their diploma covers Thursday.

Students of the Ontario High School class of 2016 received their diploma covers with an egregious spelling error on the front. Photos on social media showed the cover was spelled as “Ontario High Shcool.”

A Chaffey Joint Union High School District official told KTLA Friday that a “printing error” was to blame for the typo that was on the covers.

“The misspelling was a printing error made by the grad products company,” Chaffey Joint Union High School District Superintendent Mathew Holton said in a statement to KTLA.

Holton said that all graduates will be given a corrected diploma cover along with an apology letter.
