This paper provides a data-driven portrait of public education in Greece, documenting a series of stylized facts on learning trajectories, educational choices, university admissions, and student behavior. Drawing on newly linked administrative data that follow students across secondary education and into university applications and admissions, the paper examines how student achievement and school attendance evolve over time, how achievement gaps emerge and persist across subjects, and how academic progress varies across schools. The analysis also documents patterns in university study choices, retaking behavior in the National Exams, and the concentration of university demand across degree programs. Overall, the paper highlights emerging challenges facing the education system and identifies areas where policy debates would benefit from stronger evidence.
