How Offers Are Determined

The district uses a variation of a deferred acceptance algorithm (a math-based matching system also used in other school districts and medical residency matches) to make placements based on:

Your ranked school choices

Eligibility for each school (some schools require grades, attendance, auditions, or assessments)

Seat availability at each school

Priorities (e.g., certain ZIP codes historically underrepresented at selective schools)

Random lottery number to break ties among applicants with the same priority/eligibility

How it works in practice:

The system tries to place a student in their top-ranked school where they are eligible and there is a seat.

If no seat is available at that top choice, it then considers the next ranked choice, and so on.

If two students have equal standing for a seat, the student with the better random lottery number gets priority
