Educational policymakers and practitioners seem to be in agreement that a seamless transition from high school to college is important. Higher education has realized its responsibility and vested interest in working with the K-12 sector and has a long history of such collaboration.

The annotated bibliography lists 20 resources, all of which are in the ERIC database. (SLD)
