Every year in Minnesota, thousands of the state's children enter school unprepared for kindergarten.
And every year, the cost to the K-12 system of those children not being ready is about $113 million, according to a study released Monday.
From lost revenue after students drop out to increased safety and special education costs, the system takes a hit when students aren't ready for school, according to Robert Chase of Wilder Research, which released the study.
"The schools are losing $42 million a year just because of students dropping out early," said Chase, a consulting scientist with the St. Paul research company. "They start behind and they don't catch up."
Previous research has shown that when the state invests in early childhood education for at-risk children, there's about a 16 percent annual rate of return. But for schools, a quality two-year program for at-risk 3-year-olds would cost about $377 million per year, or more than three times the $113 million it would save, the study shows.
The moral of the story?
Maybe more than schools should be footing the early-education bill, some officials say.
"If the state is investing strategically, it would recognize that many parts of the state budget would benefit from investing in early childhood education," said Rob Grunewald, associate economist with the Federal Reserve Bank of Minneapolis. "The benefits tend to be spread out through many parts of our public budget."
