This episode follows where students and degrees went instead, from Germany, France, Japan and South Korea to partnerships and branch campuses abroad, and why quality assurance and recognition have not kept pace. It closes with the white paper's Four Routes test for deciding how to internationalize.

This episode looks at why: what employers actually do, which credentials pay, how AI is weakening cheap signals, and where the evidence is thin. It closes with the Proof-of-Skill Ladder, a way to judge whether a skill claim is strong enough to hire on.

This episode looks at trials at Harvard, in Nigeria, in UK schools, at the University of Maryland and in Turkey to ask what teachers contribute when AI can tutor, and sets out WAC's Access-to-Evidence Ladder for campus-wide AI.

Detection, grade compression and the return of admission tests are usually reported as three stories. This episode treats them as one, weighs what the evidence shows and where it is contested, and sets out what universities can do through assessment design.
