Selection, Credential Quality, and Compensatory Returns: A Course-Level Event-Study of Academic Competition Awards and Student Achievement in Chinese Higher Education
Using a course-level event-study design on Chinese undergraduate data, this paper finds that academic competition awards primarily reflect a selection mechanism where high-achieving students are rewarded, while any compensatory benefits for lower-performing students are limited to specialized coursework and require genuine competitive success rather than mere participation.

In universities across China, a student's future often hinges on more than just classroom grades. Beyond the standard lectures and exams, there is a vast ecosystem of academic competitions. These are not casual extracurricular hobbies but highly organized events where students compete to solve problems, design products, or demonstrate mastery in specific fields. Winning these contests is a powerful credential; it can open doors to graduate school, secure scholarships, and signal to the world that a student is exceptional. For years, educators and policymakers have debated what these awards actually mean. Do they act as a certificate of pre-existing talent, simply identifying students who were already the smartest and most motivated? Or do they function as a form of education in themselves, where the intense preparation and competition actually build new skills and improve a student's future performance? The answer matters deeply. If awards merely sort the already successful, then expanding these programs might just deepen inequality. If they genuinely create ability, then they are a vital tool for helping students grow.
To settle this debate, researchers at a public university in southern China turned to a massive, four-year archive of student records. They tracked 418 undergraduate students in food science and related fields, linking every single course grade they earned to the exact moment they won a competition award. This approach allowed the team to look at the same student before and after their win, effectively watching their academic trajectory in real time. They could see if a student's grades were already high before they ever stepped onto the competition stage, or if the grades jumped up only after the award was secured. They also had the unique ability to distinguish between students who earned a prize through genuine competition and those who received a certificate simply for showing up, a distinction that had been blurred in previous studies.
The data revealed a clear and somewhat surprising picture. Before winning any award, the students who would eventually become champions were already outperforming their peers by a significant margin. In fact, their grades were already about 0.44 standard deviations higher than the average student in their first year, long before they had won anything. This suggests that the competition system is very good at selecting students who are already doing well. When the researchers looked at what happened after the awards were given, they found that the winners did see a small boost in their subsequent grades, but the increase was modest—roughly one-eighth the size of the advantage they already held. The study indicates that the primary driver of the "winner's advantage" is not the award itself creating new talent, but rather the fact that the award goes to those who were already ahead.
However, the story becomes more nuanced when looking at who benefits most from the competition experience. The researchers discovered that the small gains that did occur were not distributed equally. The students who saw the most improvement were those who had been struggling the most in their regular coursework. For these students, the competition seemed to act as a different kind of engagement, a way to re-engage with their studies when the traditional classroom setting was not working for them. In contrast, the students who were already at the top of their class saw very little additional benefit. Furthermore, the quality of the credential mattered immensely. Students who received a certificate simply for participating, without having to win a competitive event, saw no academic improvement at all. Only those who actually competed and earned a prize saw any measurable gain.
The researchers also observed a dip in performance just before the awards were won. Students tended to see their grades drop slightly in the terms leading up to their victory, likely because they were diverting time and energy into preparing for the contest. After the award, their grades recovered, but the data did not show a massive, lasting surge in ability that would suggest the competition fundamentally transformed their learning capacity. Instead, the findings point to a more complex reality: these awards are not magic keys that unlock hidden potential in everyone, nor are they purely empty certificates. They are a mechanism that largely rewards those who are already successful, yet they offer a small, compensatory boost to the students who need it most, provided the award is earned through genuine competition rather than mere participation.
This study suggests that the value of academic competitions lies less in their ability to raise the average grade of a university and more in their potential to reach specific students who are underserved by standard instruction. The evidence implies that if universities want to use these programs to improve student outcomes, they should not view them as a universal enrichment tool for the already successful. Instead, the focus should shift toward encouraging and supporting the students who are currently struggling, for whom the competition might serve as a vital alternative path to academic engagement. At the same time, the rules governing these awards should be precise; giving points for participation alone appears to be a waste of policy energy, as it carries no academic weight. The true power of the system lies in recognizing that while the winners are often the ones who were already leading, the process can still offer a meaningful lift to those who need it most.
