The notion of “Liberal Arts Colleges” and “National Universities” is a false dichotomy. A more useful classification construct is to place schools within a two dimensional continuum.
One dimension is the percentage of majors that offer graduate degrees. In this dimension a “Pure College” would represent the end of the spectrum with no graduate degrees and a “Pure University” would represent the end of the spectrum with 100% of majors with graduate degrees.
The second dimension is the percentage of degrees awarded in the Liberal Arts vs the Professions. In this dimension, a “Pure Liberal Arts School” would represent one end of the spectrum and a “Pure Professional School” would represent the other.
