New Orleans College Prep, the charter school that manages Walter L. Cohen High School, may have to dip into its reserves to cover a $300,000 gap between expenses and revenues in its $11.2 million budget for the coming year, if fundraisers and donations cannot fill the shortfall, according to a report by Yomi Akinyemi for The Lens. The budget hole comes from the expiration of previous startup grants and College Prep’s increasing portion of the costs of the Cohen building.
