Any metric can be gamed (often called Goodhart’s law )—and grades are no exception, gamed both by faculty who need good ratings from students and by students who want good grades from faculty. Apprenticeships are an ideal way to bring recent college graduates up to speed on skills they need. Critical thinking presents different issues.
