Higher Education, Credentialism, and the Hidden Curriculum

Randall Collins's credential society thesis, articulated in his 1979 book The Credential Society, argues that the dramatic expansion of educational requirements for employment has less to do with increasing technical demands of work than with the use of educational credentials as tools of social closure and status competition. Collins observed that the knowledge and skills actually used in most occupations are learned primarily on the job, not in formal educational settings, yet employers increasingly demand degrees and certifications as prerequisites for hiring.

This credentialism functions as a mechanism of social stratification, restricting access to desirable occupations to those who possess the resources — financial, cultural, and social — to acquire ever-higher credentials. The massification of higher education in the twentieth and twenty-first centuries dramatically transformed what was once an elite institution serving a small fraction of the population into a mass institution enrolling millions. In the United States, enrollment in higher education grew from roughly fifteen percent of the eighteen-to-twenty-four age cohort in 1940 to over sixty percent by the 2010s.

Martin Trow's typology distinguishes elite systems enrolling under fifteen percent, mass systems enrolling fifteen to fifty percent, and universal systems enrolling over fifty percent of the age cohort. This expansion was driven by multiple forces: the post-World War II GI Bill, the civil rights movement's push for equal access, the expansion of the knowledge economy, and credential inflation itself, which pressured individuals to acquire degrees simply to maintain competitive positions in the labor market.

Critics argue that massification has not eliminated but rather restructured inequality. While more people attend college than ever before, the system has become vertically stratified, with elite institutions serving the wealthy and less prestigious institutions absorbing the influx of first-generation and lower-income students. This stratification within higher education reproduces the very inequality that expansion was supposed to address.
