Credential inflation, also called academic inflation, refers to the devaluation of educational or academic credentials over time and a corresponding decrease in the expected advantage given a degree holder in the job market, due to an excess of higher educated people who compete for too few jobs that require these degrees. Credential inflation is thus similar to
price inflation, and describes the declining value of earned certificates and degrees. Credential inflation in the form of increased educational requirements and testing, can also create artificial labor shortages. Credential inflation has been recognized as an enduring trend over the past century in Western
higher education, and is also known to have occurred in ancient China and Japan, and at Spanish universities of the 17th century. The term "academic inflation" was popularized by
Ken Robinson in his
TED Talk entitled "Schools Kill Creativity". It has been analogized to the inflation of paper currencies where too much currency chases too few commodities.
Examples For instance, in the late 1980s, a bachelor's degree was the standard qualification to enter the profession of physical therapy. By the 1990s, a master's degree was expected. Today, a
doctorate is becoming the norm. State requirements that registered nurses must hold bachelor's degrees have also contributed to a nursing shortage.
Indications A good example of credential inflation is the decline in the value of the US
high school diploma since the beginning of the 20th century, when it was held by less than 10 percent of the population. At the time, high school diplomas attested to middle-class respectability and for many years even provided access to managerial level jobs. In the 21st century, however, a high school diploma often barely qualifies the graduate for menial service work. One indicator of credential inflation is the relative decline in the wage differential between those with college degrees and those with only high school diplomas. An additional indicator is the gap between the credentials requested by employers in job postings and the qualifications of those already in those occupations. A 2014 study in the United States found, for example, that 65% of job postings for executive secretaries and executive assistants now call for a bachelor's degree, but only 19% of those currently employed in these roles have a degree. Jobs that were open to high school graduates decades ago now routinely require higher education as well—without an appreciable change in required skills. In some cases, such as IT help desk roles, a study found there was little difference in advertised skill requirements between jobs requiring a college degree and those that do not. That distribution has remained largely unchanged for thirty years, although the chance of being underemployed in a good job has gone down 28.0% for recent hirings, and 20.6% overall.
Causes The causes of credential inflation are controversial, but it is generally thought to be the result of increased access to higher education. This has resulted in entry-level jobs requesting a bachelor's (or higher) degree when they were once open to high school graduates. Potential sources of credential inflation include: degree requirements by employers, self-interest of individuals and families, increased standards of living which allow for additional years of education, cultural pushes for being educated, and the availability of federal student loans which allow many more individuals to obtain credentials than could otherwise afford to do so. In particular, the internal dynamics of credential inflation threaten higher education initiatives around the world because credential inflation appears to operate independently of market demand for credentials. The push for more Americans to get a higher education rests on the well-evidenced idea that those without a college degree are less employable. Many critics of higher education, in turn, complain that a surplus of college graduates has produced an "employer's market". Economist
Bryan Caplan has argued the combination of more college graduates and weaker learning outcomes has led to employers asking for college degrees for jobs that do not need one and previously did not require one.
Problems Credential inflation is a controversial topic. There is very little consensus on how, or if, this type of inflation impacts higher education, the job market, and salaries. Some common concerns discussed in this topic are: • The proliferation of a grandiose and superficial culture has engendered a paradoxical phenomenon within China's employment landscape, particularly evident in the disproportionate educational requirements for roles traditionally devoid of such stipulations. Previously, there were no academic qualifications required for security guard positions. However, it has come to light that some employers are now demanding that applicants for such roles possess a master's degree or higher. And in fact, many jobs do not require formal education and can be adequately performed after on-the-job training or apprenticeships and those applicants who meet the educational requirements and are hired by employers often find that the subject of their diploma does not align with the work they are doing. They have to start from scratch in their jobs, causing a waste of educational resources. • College
tuition and fee increases have been blamed on degree inflation, though the current data does not generally support this assertion. • Credential-driven students may be less engaged than those who are attending college for personal enrichment. • Credentialism is prevalent in China, where children from impoverished families pursue higher education but cannot afford the associated costs. They are often forced to attend public schools or non-profit charitable universities, which have lower tuition than private institutions, yet even these fees remain a heavy burden. To pay for tuition, they economize on living expenses to the extreme. This situation, coupled with education inflation leading to the rapid devaluation of university degrees, means that when these graduates enter the job market, their employment prospects are often worse than anticipated. Since the tuition paid consumed a large portion of their poor families' expenditure, this disproportionate return on investment leads to feelings of disappointment and dissatisfaction among the children from these families. On the other hand, education inflation has led to many people holding a bachelor's degree or higher, and these highly educated individuals often have high expectations when job searching, believing they can secure high-paying positions commensurate with their academic qualifications. However, in reality, the professional skills of many graduates are misaligned with market demands; the market under-demands certain skills while certain specializations suffer from oversupply. Consequently, they are forced to accept jobs that are either mismatched with their majors or low-end positions for which they are overqualified. This mismatch of education to job results in a severe misallocation of human resources, and low-end employment leads to a waste of social resources. Furthermore, the vast gap between their ideals and reality forces these highly educated individuals to endure the heavy toll of mental exhaustion and low spirits over the long term. • Devaluation of other forms of learning. • Before educational inflation, the diploma gap was not significant, and employers did not have high diploma requirements for job applicants. After educational inflation, people's educational qualifications became uneven, and employers raised the diploma requirements for recruitment. Those who could not meet the diploma threshold for recruitment had to resort to joining the underworld out of desperation to make a living, while women were forced to become hostesses or sex workers – jobs that do not require diplomas. Moreover, not all individuals lacking the relevant diplomas are poor students. Some students who excel in specific areas may struggle with the comprehensive general education requirements, preventing them from obtaining the necessary diplomas. •
Opportunity costs of attending graduate school, which can include delayed savings, fewer years in work force (and less earnings), and postponement of starting families. • Educational inflation has made mate selection difficult for women, who prefer partners with equal or higher education. In China, for example, mate selection was relatively easier for women before educational inflation because educational disparities were smaller. However, after educational inflation, the gap in academic qualifications has widened, the length of education has increased, and the time to enter the workforce has been delayed; in addition, women are unwilling to marry men with lower educational qualifications than themselves, leading to a significant increase in the number of single women in China. Even if a man is exceptionally talented, a mere lack of sufficient educational credentials is enough to deter women from even wanting to get to know him. • Lack of adequately trained faculty and rises in the number of
adjunct professors which can adversely impact quality of education. • Grade inflation has been correlated to degree inflation by some academics, though the causal direction is debated. • Some in-service employees or government officials in China, despite being experienced in their work, are forced to pursue higher education, such as associate degree to bachelor's degree, master's or doctoral degrees, due to the lack of high educational requirements when they were first hired. This diverts their energy from work, and sometimes the field of study is not relevant to their job. As a result, obtaining a degree does not necessarily improve their work abilities • Although honorary doctorates are intended to honor individuals for their exceptional contributions or social influence in a specific field, and do not require coursework, exams, or thesis defenses, the proliferation of regular doctoral degrees has diluted the prestige of honorary doctorates • In April 2025, Peking Union Medical College in China was exposed by the media to have launched a clinical medicine doctoral training program in 2018 known as the "4+4" model, which consists of 4 years of non-medical undergraduate education followed by 4 years of medical professional education. The program uses the theory of liberal education as a justification, arguing that doctors should possess a broader knowledge base beyond medicine. This has sparked a debate between liberal education and specialized education. The public has expressed disapproval, claiming that it not only wastes the first four years of undergraduate study but also results in doctors trained under the liberal education theory lacking adequate medical skills. Furthermore, the program has been criticized as a shortcut for children of powerful and wealthy families to quickly obtain a doctoral degree. ==Grade inflation==
