In 1980, when William Winter became governor of Mississippi, there was no state funded kindergarten. School attendance was not compulsory. Mississippi ranked last in the nation among most educational indicators. And in the more than 25 years that had passed since the 1954 Brown vs. Board of Education decision, the state had not been able to come to terms with school desegregation.
In 1982, Gov. Winter succeeded, against all odds, in passing the most sweeping education reform the state had ever seen, which among other things established kindergarten for all Mississippians.
