Some Wisconsin parents are complaining that state grants for college tuition are falling far short of what they thought Gov. Jim Doyle had promised, the Associated Press reported. The Wisconsin Covenant program has enrolled 50,000 eighth graders over the past three years, but Governor Doyle, a Democrat, only recently announced details of the grants it would pay. Those range from $250 to $2,500, based on family income. At a legislative hearing on Monday, some parents complained that they had thought the grants would cover the entire cost of college.
