CPE's "double the numbers" plan calls for 397,000 bachelor's degrees to be awarded between 2005 and 2020. It also identifies changes we'll need to make further back in the "pipeline" that leads to those degrees, including these:
postsecondary enrollment from 3.6 percent to 4.5 percent of the adult population. I haven't yet worked out how to put numbers on that part of the change.
Note: The diploma and GED numbers above are listed in the plan document (here). Moving the high school direct to college rate from 62% to 74% and the GED to college rate from 19% to 36% produces the other numbers.
