It's a lesson as fundamental as the ABCs: Students can't learn if they don't show up.
Research shows that kids in poverty coming to class can single-handedly improve student achievement. Schools across the Twin Cities offer rewards and mentoring to keep kids in school. Despite all the attention and effort, Minnesota has no clear handle on the hundreds of schools with serious attendance problems.
Now the state is buckling down on efforts to bring those kids back to class and rethinking the way it tracks school success, spurred by a change in federal law. If all goes as planned, in addition to keeping tabs on test scores and graduation rates, Minnesota will pinpoint the number of kids with severe absence streaks starting in fall 2018.
"Research says it's a strong predictor of whether students will drop out, and a strong predictor of a student that may fall behind academically," said Stephanie Graff, the Minnesota Department of Education's chief accountability officer.
The push to refill vacant classroom seats is winning nationally. At least seven other states and Washington, D.C., have made some plan to focus on this issue, called chronic absenteeism.
Minnesota's focus on chronic absenteeism is part of a school improvement plan that will be shipped off for federal approval in September. The plan would identify schools falling short on a combination of student achievement factors, including high numbers of absent students.
One count of state numbers shows that one in 10 kids across Minnesota — many in urban schools — missed roughly a month of school last year, or more than 10 percent of all school days.
"We're starting to see really promising evidence that if you turn it around, we can make a difference," said Hedy N. Chang, who heads up Attendance Works, a national group that has monitored student attendance and urges districts to do so, too. A study using data from the 2013-14 school year found that half of the 6.5 million chronically absent students nationally are in 4 percent of school districts.
