Portugal views its education system as a key driver of social mobility since the 1974 revolution, but this 'elevator' is increasingly restricted. A new study by the La Caixa Foundation and BPI reveals that 20% of students—rising to one in three in secondary education—rely on private tutoring, costing families nearly 300 million euros annually. Wealthier families spend 30% more on these services, gaining a competitive edge in grades and national exams. While the system still promotes some mobility, it is increasingly reinforcing inequality, as academic success becomes tied to the ability to pay for extra support and elite schooling.
