It&#x27;s easy to quantify quality of instruction. Just longitudinal analysis. Messy? Probably. But in serious industries, it would be done. But higher education administrators would rather listen to instructors than students and instructors <i>really</i> don&#x27;t like the idea.<p>If parents had to pay directly for college, I suspect longitudinal tracking of students to assess influence of prior instructors would start in a hurry.<p>As a med student, I presented a poster at a medical education conference. The most common comment was &quot;Woah! Data!&quot; A brief tour of the faculty presentations indicated this field of study is a protectionist racket. Nothing good will come of it.
