Admissions

Admissions
STEP 1. Online Application & Tours

Begin with the online application. An optional guided campus tour can be scheduled on the same day as the admissions interview or separately. Invitations are sent by the Admissions office after the online application and all required documents.

STEP 2. Interview & Testing

Upon completion of the online application and submission of all required documentation, the family and applicant are invited to an Admissions Interview and family meeting with the Head of Admissions and often other Admissions Committee Members. We prefer to meet families in school, but online meetings and admissions testing are available if in-person attendance is not possible. The interview process differs by age group. Foundations (children aged 3 as of August 31) and Pre-Kindergarten (children aged 4 as of August 31) participate in group interviews; sessions typically begin on Saturdays in late January for 2-3 weekends and continue later in spring, with individual arrangements if needed. Kindergarten involves individual admissions interviews. Grades 1–5 involve an essay writing component, and, if English proficiency is sufficient, a MAP test; English language learners may be asked to complete English placement assessments; interviews may be onsite or online for families outside Luxembourg. Grades 6–10 require a CAT4 assessment, an online English placement test if English is not the first language, with additional testing in English writing and Mathematics sometimes requested; applicants have a separate discussion with a relevant admissions committee member. Grade 11 requires a CAT4 assessment, an online English placement test if needed, an English essay, and a Mathematics test, followed by a separate admissions discussion. Grade 12: please contact the Admissions Office.

STEP 3. Decision

For the ongoing school year, decisions are shared within 10 school days after the admissions interview. For the next school year, foundations and pre-kindergarten first decisions are available mid-February; Kindergarten through Grade 11 first decisions are available late March or early April, thereafter within 10 school days after the admissions interview. Grade 12: please contact the Admissions Office.
