NEW YORK (TheStreet) -- In the U.S., an average of only 55.5% of college students graduate within six years, while just 69% of students earn their high school diploma.
Despite these grim numbers, a report released by the America's Promise Alliance said the country is on the right track, estimating that by 2020 the high schools in the country will be able to achieve a 90% graduation rate.
The American Legislative Exchange Council recently published the 18th edition of its state education rankings the Report Card on American Education.
The Report Card "is a comprehensive overview of educational achievement levels, focusing on performance and gains for low-income students" and ranks states based on several criteria including state academic standards, private school choice programs, charter schools, teacher quality and online learning opportunities.
Just because a state has a low overall education grade doesn't necessarily mean that their education policy is not on the right track. Oklahoma is ranked as the 9th worst state on this list, but its overall education grade of "B+" indicates that its policy is on the right track, according to the ALEC.
Here is a list of the 10 states ranked last in the report.
Education Policy Grade: C-
Teacher Quality and Policies Grade: C
Per Pupil Expenditure: $10,555
Kentucky ranks 35th in country with 47.8% of college students graduating with a bachelor's degree within six years. Of the students who graduate high school and go on to college, 71.8% of Kentucky's college freshman go on to their sophomore year, ranking the state 38th in the country for college retention rates.
