Admissions 1. Submit the Application. Prospective families must submit the online Admission Application Form and pay a €500 deposit to confirm registration; this deposit serves as payment for the first month's tuition. Applications should ideally be submitted three months prior to the start of a new school year, though they are accepted throughout the academic year. Earlier applications increase the likelihood of enrollment. The TISA academic year runs from September to mid-July. For mid-year entries, student placement is based on the grade most recently completed at the previous school. 2. School Tour/Meeting. The Admission Team carefully reviews each application and schedules a school tour and meeting with the prospective family. The purpose of this meeting is for the school and the family to become acquainted and to address any questions. Tours can be scheduled via the provided calendar link. 3. Sign the Agreement. Following the meeting, the school reserves the applicant's spot—including any applicable discounts—for a period of two weeks, pending the signing of the School Fee Agreement. Once the document is signed, families receive a formal placement confirmation and onboarding instructions for new TISA students. Signing the School Fee Agreement officially confirms the obligation to pay the associated school fees.
