More than 16,000 score free college tuition
By Marie Szaniszlo Boston Post September 16, 2006

State education officials yesterday mailed letters to each of the 16,169 class of 2007 high school students who qualify for a John and Abigail Adams Scholarship, offering four years of free tuition at any public Massachusetts college.

"*A 2 child family earning $50,000 gets $2,050 or 1/5 the cost of public college for one kid."

Oklahoma Higher Learning Access Program: Oklahoma residents with a family income of less than $50,000 at the time of enrollment who maintain a 2.5 high school GPA and take a set of required college-preparatory courses can receive free tuition at Oklahoma public institutions and partial tuition at Oklahoma private schools if they maintain a 1.7 GPA for their first 30 credit hours and a 2.0 GPA after that.
