Can this be extrapolated?

That problem is this: across the board, American colleges and universities are not doing a very good job of preparing their students for the workplace or their postgraduation lives. This was made clear by the work of two sociologists, Richard Arum and Josipa Roksa. In 2011 they released a landmark study titled “Academically Adrift,” which documented the lack of intellectual growth experienced by many people enrolled in college. The authors examined the results of tests taken at the beginning, middle and end of students’ undergraduate careers and concluded that 45% of students “did not demonstrate any significant improvement in learning” during their first two years of college, while 36% failed to demonstrate improved learning across all four years. In particular, Arum and Roksa found, college students were not developing the critical thinking, analytic reasoning and other higher-level skills that are necessary to thrive in today’s knowledge-based economy and to lead our nation in a time of complex challenges and dynamic change.
