True or False: "School is all about signaling, not skill-building"

I read Professor Caplan’s LA Times article “What students know that experts don’t: School is all about signaling, not skill-building” again.

This work product can only have been produced by one immersed in academia and unfamiliar with the reality of today’s workplace.

Professor Bryan Caplan’s article attempts to support two assumptions:

  1. The main reason firms reward education is because it certifies (or “signals”) brains, work ethic, and conformity."

  2. Educational austerity is the simplest path back to an economy in which serious on-the-job learning starts during high school–not after college.

With respect to point #1, Professor Caplan might be confusing the granting of an interview with a job offer. Firms grant job interviews to those meeting certain requirements. Job offers are made to those who pass multiple screening tests.

Regarding point #2, serious learning does begin in high school. Maybe Professor Caplan is confusing trade schools with the primary goals of education: Communication Skills & Problem Solving Skills.
