When report cards went out for students in the Clarksville-Montgomery County school district in October, most of the 29,000-plus students did not have a printed version for their parents to sign.

That's because the district went largely paperless with its report cards for the first time, making grades available to parents with secure accounts online, says communications manager Michelle Newell. A growing number of districts nationwide are making the change says Ann Flynn, director of education technology with the National School Boards Association.
