Students in Anne Arundel County won't go to school for 180 days this year, thanks to last month's record-breaking snowstorms. State schools Superintendent Nancy S. Grasmick has granted the county's request for a five-day calendar waiver. That means the school year will end June 15, so long as there are no more emergency closings. Anne Arundel schools built four snow days into the calendar but have used 10 this winter. Grasmick says she granted the waiver because the system added one day to the end of the school year and because it plans to "concentrate instructional time to make up for lost school days." The state school board gave Grasmick the authority to grant waivers on a case-by-case basis. Officials with the Maryland State Department of Education say Grasmick also granted waivers to five other counties: Charles, Frederick, Kent, Prince George's and St. Mary's. In Kent, Prince George's and St. Mary's counties, students will be in class for 175 days this school year. Charles and Frederick counties received three-day waivers, meaning they'll have 177 instructional days.
