Matthew Effect in education refers to the cumulative advantage process in which learners who begin with stronger skills, knowledge, or support tend to gain increasingly more over time, while those who start with fewer resources or weaker foundations fall progressively behind ^[1][2]. In educational contexts, it is commonly observed in literacy, language, and academic achievement trajectories, where early differences are amplified through unequal access to practice, feedback, expectations, and opportunities ^[1][2]. The concept is characterized by self-reinforcing divergence: prior success increases the probability of future success, and prior difficulty increases risk of continued underperformance. As an analytical term, it denotes a dynamic mechanism of widening educational inequality over time, rather than a single-point difference in achievement
