UPPER MARLBORO, Md. (AP) — High school diplomas in Prince George’s County are being reprinted because they contain a spelling error.

All of the diplomas distributed last week misspelled the word “program.” County officials say they noticed the mistake after commencements were underway.

The Fairfax County vendor that printed the nearly 8,000 diplomas, National Quality Products, has apologized to the Class of 2012 for the mistake. Briant Coleman, a spokesman for the schools, said the vendor will reprint the diplomas for free.

The corrected diplomas will be mailed to students in a little more than a month.
