Luxembourg's national primary education (cycles 2 to 4) had 37,329 pupils in 2025/2026, according to Luxembourg in Figures 2026 from STATEC and the education ministry. Pre-primary education had 13,368 pupils and early childhood education 5,129. National secondary education had 27,480 pupils in general secondary education and vocational training and 19,729 in classical secondary education.

The count of students abroad only includes residents who applied for financial aid for an eligible programme, so the true number may be higher. Since 2023/2024 it counts winter semester enrolments only.
