At a time when more high schools are looking to their graduates' college-remediation rates as a clue to how well they prepare students for college and careers, new research findings suggest a significant portion of students who test into remedial classes don't actually need them. Separate studies from Teachers College, Columbia University, and the Harvard Graduate School of Education come to the same conclusion. The problem is coming to the fore as more states move to align their academic standards for college and career readiness with the Common Core State Standards and federal Race to the Top requirements and more high schools receive data on how their graduates are faring in colleges.
