2026-2027 Pricing:
The SI Bus Service pricing reflects our contracted rate with Catholic Charities CYO Bus Transportation (CCCYO). We are committed to keeping this student service as affordable as possible for our families. As with many services, rising costs for diesel fuel, fleet maintenance, and staffing have led to a 9% increase in our transportation contract for the 2026-27 school year compared to the prior year. The SI Business Office attempts to price this service on a cost-neutral basis and without impact to tuition or the broader school community.
Pricing Breakdown:
- Full Year Round Trip: $4,000
- One Semester Round Trip: $2,400
- One Way Full Year: $2,450
- One way Semester: $1,650
Limited one-time use tickets (for single use morning or afternoon) are also available at the Main Office from Ms. Kathleen McKeon: $20/day. These tickets may be purchased with check, cash or MySchoolBucks.
