NASHVILLE (AP) — Tennessee has been recognized as one of the top states in the nation for its efficient use of digital technology.

Gov. Bill Haslam announced this week that the state was among six to receive an A-minus in the 2012 Digital States Survey, one of the nation's longest running examinations of technology use in state government.

Tennessee's grade was up from a B-plus, which it got in the 2010 survey. Michigan and Utah were the only two states to receive an "A."

Criteria used to grade states include savings or benefits, progress over the last two years, innovative solutions or approaches, and effective collaboration.

Haslam says Tennessee is always looking for ways to improve the delivery of state services to taxpayers, and "will continue to enhance online options."
