How much do international schools cost in Luxembourg in 2026?

The International School of Luxembourg (ISL) publishes total annual school fees that recently sit near €19,805 for Early Years to Grade 1, about €21,400 for Grades 2–5, and roughly €23,200–23,450 for middle and high school once the growth fund and stability reserve join tuition. Those figures already reflect Luxembourg’s private-school state subsidy; without it the school notes tuition would rise by a similar four-figure amount per child.

St George’s International School (British curriculum, Hamm area) publishes full-year totals commonly near €14,750 in early years, rising through the mid-teens into about €19,550 for upper years when building and stability funds sit with tuition. Application and deposit lines add further cash in year one.

European School Luxembourg I and II charge Category I (EU-institution) pupils differently from Category III outsiders. Recent Category III minerval bands sit around €4,200 for nursery, €5,800 for primary and €7,900 for secondary, with a large non-refundable deposit share billed up front. Places are contested; company agreements can change the category story. Always read the school’s live fee note for your child’s cycle.
