Wait Pool
Why was my application placed in the wait pool?

Qualified applicants who are not accepted due to space availability are placed in our wait pool and will be considered if spaces become available. YISS strives to maintain a balance in gender and diversity and to ensure academic success and availability of needed programs or classes.

Does space become available during the school year?

Students may withdraw at various times during the school year. If and when a space becomes available, the admissions office considers all students in the wait pool and selects an applicant that best complements the class.

Is the wait pool chronological? Does it matter when I apply for my child?

No, the wait pool does not have a chronological or predetermined order based on order of receipt of application. Consequently, the admissions office cannot provide numbers for students in the wait pool or predict availability as our numbers can change daily. However, we will try to be realistic with families about their chances of being admitted in a certain grade at a particular time.

How often do I need to update the applicant’s school records while in the wait pool?

If you continue to have a strong interest in your child’s acceptance during the school year, it is important to keep the application current by sending recent school records as they become available. In the event of a mid-year vacancy, immediate decisions can be made only on complete and current files.

Is the wait pool maintained from year-to-year?

No. The wait pool is maintained for the applying year only. All applicants who are interested in any subsequent year must reapply.
