For the first time, all DeKalb County School District classrooms have wireless access.

Superintendent Michael Thurmond announced Monday that an installation process that started early this year has been completed within budget at a cost of $4.5 million.

The ubiquitous access means students don’t have to take turns in a computer lab, and “technology-based learning” can occur in the classroom. Teachers will have flexible access to grade books, student data and other content while administrators will be able to use mobile devices to observe classrooms, monitor student behavior and make testing easier and more efficient, according to the district.
