(NPN) -- Four of the 10 states in the nation that do not provide state-funded pre-school are in the Northern Plains—South Dakota, North Dakota, Montana and Wyoming—according to a new report released the U.S. Department of Education.

Iowa, Nebraska and Minnesota do offer state funding for 3 and 4-year-olds to attend pre-school.

Iowa had one of the highest rates of 3 and 4-year-olds participating in state-supported pre-school at 32.4 percent. Nebraska had 18.6 percent of its toddlers and Minnesota had 1.2 percent.

Nationally, the study noted that states with funded programs had a rate of 17.6 of toddlers in pre-school and all schools (state funded and non-funded) had a rate of 16.4 percent.

Minnesota spent the most per child in the region at $7,292, followed by Iowa at $3,150 and Nebraska at $2,943.

As of July 2012, South Dakota had 24,086 3 and 4-year-olds, a decrease of 233 children from July 2011.

More than 70 percent of the 4-year-olds in Florida, Oklahoma, Vermont and the District of Columbia participate in pre-school, according to the report.
