Graduates at a Southern California high school were given diploma covers with a typo.
Ontario High School handed out diploma covers with the letters "h" and "c" transposed in the word "school."
School officials said the misspelling was a printing error made by the graduation products company.
"The principal has informed all Ontario graduates that the company has been contacted
"They will mail a corrected diploma cover to each graduate along with an apology letter," Chaffey Joint Union High School District Superintendent Mathew Holton said.
The diploma covers were distributed to about 550 seniors at a Thursday evening commencement ceremony.
