The announcement came earlier this month by Character.org. Well done!
From the press release … 
Character.org, the nonprofit organization that validates character initiatives in schools and communities around the world, today designated 83 schools and 4 districts from 21 states as 2017 National Schools and Districts of Character.
The School District of South Milwaukee is the only Wisconsin district currently designated as a National District of Character. South Milwaukee School Superintendent Rita Olson announced the news at a recent staff meeting. “This recognition is a testament to the hard work and relentless focus on character that our schools and community support. We are committed to educating the whole child and this is one way that we prepare our students for a successful future,” remarked Olson.
