Step 3: Submit the relevant documents. For Early Years there is no requirement to submit documentation prior to enrollment.

Afterward, there is a consultative meeting with the relevant Department Head; for middle and upper school, the evaluating psychologist discusses the results. Step 5: Offer of a place. If the application is approved, the Admissions Team extends an offer of enrollment contingent on space availability. A Confirmation of Acceptance will be sent to you via email after we receive the full registration fee, which is non-refundable.
