Furthermore, this picture understates the region’s dominance because it excludes mainland China from certain datasets. While China was not part of that specific dataset, its major metropolitan areas—specifically Beijing, Shanghai, Jiangsu, and Zhejiang, collectively known as BSJZ—actually ranked higher than Singapore in the 2018 PISA results. East Asian educational systems demonstrate similar strength in reading comprehension, claiming four of the top five spots globally. This achievement is particularly striking when considering that writing systems based on characters, such as those utilized in Japan and China, are substantially more complex and demanding to learn than the alphabetic systems employed across most European languages.
The most immediate explanation offered by researchers for this sustained scholastic performance is cultural. Of the six East Asian countries that top the PISA rankings in mathematics, all but Japan exceed the Organization for Economic Cooperation and Development (OECD) average for weekly hours spent on classwork. When including the combined Chinese cities of BSJZ, three jurisdictions rank in the global top seven for total hours dedicated to studying. Beyond the standard school day, many students in these high-performing countries attend evening "cram" schools long after their regular classes have concluded.
Whether this intense focus on academics represents a net positive for society remains a subject of considerable debate. On one hand, a fiercely competitive academic culture can severely limit opportunities for children to play, socialize, and develop outside the classroom. To the extent that the specialized academic knowledge acquired during these years proves irrelevant to many future professions, critics argue that this intensive approach may act as a net-negative that places a drag on societal well-being and economic flexibility.
Conversely, it is difficult to ignore the extraordinary economic performance of East Asian economies—most notably the Four Asian Tigers of Hong Kong, Singapore, South Korea, and Taiwan—particularly within high-technology manufacturing and global trade. It is hard to look at these advanced economies and conclude that an intense societal focus on mathematics and science has not yielded profound economic dividends.
While researchers and policymakers frequently debate the relative merits of different educational philosophies—including intriguing outliers within East Asia, such as Japan’s ability to secure high student achievement with comparatively fewer weekly hours of study—a deeper historical question remains. What are the true origins of these educational cultures? Why did such an intense, enduring societal emphasis on educational attainment develop in East Asia in the first place?
The Keju: 1,300 Years of Studying
One compelling historical explanation for the contemporary cultural emphasis on education traces back to the long-lasting influence of the Chinese civil service examinations, known historically as the keju. While medieval Europe was developing feudal structures rooted in hereditary land tenure and noble birthrights, the imperial Chinese state was staffed by a sophisticated, meritocratic bureaucracy. This bureaucracy was populated entirely by graduates of some of the most competitive, rigorous examinations the world has ever witnessed.
To understand the mechanics and societal implications of this system, scholars often examine historical analyses such as Ichisada Miyazaki’s classic study, "China’s Examination Hell," which details both the profound benefits and the immense human costs generated by the system. Initiated during the Sui dynasty in 605 CE, the civil service examinations were originally conceived as a political tool to circumvent powerful aristocratic families who wielded dangerous levels of control over the imperial government.
In theory, these examinations were open to virtually all men, offering a theoretical pathway of social mobility that was revolutionary for its era. Any male subject, ranging from the son of a wealthy noble family down to a peasant commoner, was permitted to sit for the preliminary tests. In practice, however, the immense financial burdens associated with years of full-time study meant that very few individuals outside of already privileged backgrounds could seriously pursue them.
Nevertheless, the system provided a tangible degree of social mobility, helped legitimize imperial rule across changing dynasties, and served as a powerful mechanism to centralize political power. For these fundamental reasons, despite dynastic collapses, internal rebellions, and even foreign conquests, the examination system persisted for thirteen centuries. It was finally abolished only in the waning days of the Qing dynasty.
Even historical figures who suffered under the system’s crushing pressure acknowledged its inescapable necessity. Hong Xiuquan, who suffered a nervous breakdown after failing multiple times to become a licentiate, subsequently convinced himself that he was the younger brother of Jesus Christ and launched a devastating civil war that cost tens of millions of lives. Yet, despite his personal trauma, Hong still established his own version of the examination system within the territories under his control. The exams were simply viewed as an essential component of governance and social order.
What Was It Like Taking the Exams?
Historical accounts of the examination halls highlight not only the vast scope of the curriculum—which centered on the exhaustive memorization of the classical Chinese philosophical texts—but also the grueling physical and psychological realities experienced by the test-takers. At the peak of their complexity during the late Qing dynasty, the examinations were divided into three major tiers: provincial, metropolitan, and palace examinations.
The provincial examinations, held nominally every three years, required candidates to be locked inside tiny, isolated cells within massive, labyrinthian examination compounds for three continuous days. Each candidate was provided with just three wooden boards: one configured for sleeping, one for sitting, and one to serve as a writing desk. Because these sprawling facilities were used so infrequently, they were frequently dilapidated, forcing students to desperately shelter their precious answer sheets from leaking rainwater.
Test-takers faced not only harsh physical confinement, but also profound psychological pressures, including pervasive fears of supernatural retribution. It was widely believed within the culture that divine or ghostly forces would punish individuals guilty of hidden, unpunished crimes during their time in the exam cells. Seducers, swindlers, and wrongdoers anticipated being haunted, with numerous historical anecdotes attributing nervous breakdowns or suicides during the three-day confinement to a guilty conscience.
In other instances, karmic retribution manifested through frustrating accidents. A past transgression might allegedly result in lamp oil accidentally spilling across an answer sheet, a procedural violation that led invariably to immediate failure. Within this framework, any apparent unfairness in the grading results was frequently interpreted by contemporaries not as random bad luck, but as hidden moral transgressions being judged directly from heaven.
The few candidates who successfully navigated the provincial rounds made the long and expensive journey to the capital for the metropolitan examinations. In the early centuries of the keju, these served as the final stage of the scholar’s journey, after which a successful candidate secured a near-guaranteed appointment within the imperial bureaucracy.
Yet, this stage introduced political complications. Test-takers owed profound loyalty to the specific examiners who passed them, creating dangerous political factions within the government—much like modern academic researchers who frequently owe their career trajectories to prominent doctoral advisors. To prevent these loyalties from undermining the authority of the throne, the final palace examinations, judged personally by the emperor, were formally instituted. This structural adjustment ensured that successful graduates owed their ultimate gratitude and political allegiance directly to the emperor rather than an intermediary examiner.
Given the enormous career incentives at stake, the system was vulnerable to corruption, prompting authorities to implement elaborate anti-cheating measures. Candidates were thoroughly searched for smuggled reference materials before entering the cells. To prevent examiners from favoring specific families, graders were only given access to a candidate’s seat number rather than their name. In the higher-level examinations, scribes meticulously hand-copied every answer sheet to ensure that a candidate’s identity could not be guessed through distinctive handwriting. When corruption scandals did occasionally surface, the public backlash was so severe that authorities were strongly motivated to maintain the appearance of absolute integrity, and examiners found guilty of tampering were frequently exiled or executed.
The overall attrition rate was staggering. A candidate first had to pass a local qualifying exam just to enter the official system, an initial hurdle with a pass rate of only one to two percent. Provincial exams featured a pass rate of roughly five percent, while metropolitan exams hovered between 15 and 20 percent. Although very few candidates failed the final palace exams—which functioned more as a ranking ceremony than an eliminative test—the specific placement a scholar achieved profoundly influenced his subsequent career trajectory. Out of more than a hundred thousand initial hopefuls across the empire, perhaps only a dozen would ultimately see their ambitions fulfilled by achieving the highest classification of palace graduates.
Unlike modern university systems where academic credentials are acquired in early adulthood, the process of studying for and taking the imperial exams could span decades. It was entirely common for newly minted graduates to be elderly men with gray hair. In some instances, aging, persistent candidates were granted honorary degrees simply to acknowledge a lifetime of effort, knowing they had already surpassed the standard retirement age for official government posts.
Legacy of the Imperial Examination System
Determining the precise, quantifiable impact of China’s historical examination system on modern educational achievement across East Asia remains a complex challenge for researchers. One prominent empirical study utilized natural variations in historical exam intensity within China—measured by the density of high-level graduates per capita—and discovered that regions with a historically higher concentration of graduates currently exhibit higher levels of educational attainment today.
Other scholars remain skeptical about drawing such a direct, unbroken line across centuries. For generations, China exerted immense cultural influence over its neighbors. Even countries like Japan, which never adopted an indigenous imperial examination system, enthusiastically embraced broad aspects of Chinese civilization, ranging from writing systems to philosophical frameworks. It is entirely plausible that cultural attitudes toward learning diffused throughout the region even in the absence of a formalized bureaucratic testing apparatus.
Nevertheless, the historical legacy of the keju offers vital context for understanding modern educational priorities. For well over a thousand years, the examination system fostered a cultural reverence for formal education that had no historical parallel in Europe until much later centuries.
Despite its notable flaws and rigid conservatism, the keju was remarkably progressive for its time. Allocating state authority and government positions based on competitive merit rather than noble birthright was virtually unknown in Western societies until the nineteenth century. The fact that this structured meritocracy emerged concurrently with the rise of feudalism in Europe and endured until the dawn of the twentieth century remains a monumental historical achievement.
The cultural footprint of the keju extends far beyond the classroom, deeply influencing societal values regarding governance and military power. Historically, parallel military examinations existed alongside civilian ones, but success in military tests rarely translated into high social prestige or supreme government office. Military generals faced institutional limitations on their advancement, which helped ensure robust civilian control over the armed forces and contributed to long periods of internal stability.
At the same time, this extreme centralization of state power and bureaucratic control may have carried unintended long-term costs. While the system arguably fostered stability and peace, some economic historians argue that such rigid administrative centralization may have discouraged the decentralized, disruptive innovations that eventually catalyzed the Industrial Revolution in Europe.
Furthermore, the narrow content of the exams has invited enduring criticism. Although studying the classical texts was intended to cultivate moral judgment and administrative wisdom, the practical utility of memorizing ancient literature for modern governance has always been questionable. From a contemporary educational perspective, dedicating decades of a human life to mastering skills far removed from practical problem-solving appears profoundly inefficient.
This dynamic invites modern comparisons. As advanced economies experience credential inflation—where university degrees and advanced certifications become baseline requirements for jobs that do not necessarily demand specialized academic capital—society must grapple with its own educational priorities. Future generations may look back at contemporary obsession with standardized test scores, university rankings, and academic credentials with the same critical eye applied to the historical study of imperial classics.
Ultimately, whether future societies view the legacy of the keju as an essential, visionary forerunner to a meritocratic, knowledge-based society, or as an exorbitantly wasteful scholastic competition, reveals as much about the evolving role of education in modern culture as it does about the historical institution itself. The imperial examination system endures as a fascinating window into the deep-seated historical forces that continue to shape how societies value learning, competition, and human potential today.
