1. Grade Level Placements: New students gain admission based on official school records for the last two years, showing the student is succeeding at or above the average in a mainstream classroom. Students entering from a U.S.-based system are placed with their age group, typically Kindergarten at age 5 and about 13 years of schooling before university entrance around age 18. Students entering from a British-based system are placed by age and years in school; those from other calendars are placed on a case-by-case basis. Any initial placement is tentative and may be adjusted after assessment, and entrance testing may be required for all applicants. 2. Age Appropriate Placement: The designated grade level is determined by the student's birthdate. Early Childhood 1 requires age 3 by August 31; Early Childhood 2 requires age 4 by August 31; Kindergarten requires age 5 by August 31; Grade 1 requires age 6 by August 31; and so on up through Grade 12, with specific birthdate cutoffs listed for each grade. Children entering AISL's Early Childhood Program must be toilet-trained prior to the first day of school in August. 3.

If admission is not possible, a denial is issued by email and the portal. 7. Student Assessment: Applicants may be called in for an entrance assessment when a vacancy occurs at the appropriate grade level; the assessment may include basic skills, vocabulary, reading comprehension, spelling, mathematics and written expression, and students must score at or above grade level to be admitted. 8. Waitlist: If an application meets admission requirements but the grade level is full, the applicant is placed on the waiting list. The waiting list is maintained by the date of the completed application and priority category. The position on the wait list can change if new applications from other categories are received. Parents must email the Admissions and Enrollment Management Office to update their child's file at least every six months (also via the Admissions Portal) to keep the application active; failure to update can result in removal from the waitlist.
