Cardinals, It's time to dust off those backpacks, sharpen those pencils, and get ready for another year of learning and growth. Welcome back, students! We've missed your laughter, curiosity, and unique perspectives. This year holds endless possibilities, and we're excited to embark on this journey with you. Let's make it a memorable one together!
Stay up to date on what is happening in and around Costello. Read the current issue of the Cardinal Connection Parent Newsletter and share in all that our students have achieved and/or celebrated.

The Troy School District is grateful to our community for their support and passage of the 2022 Bond representing a $555 million dollar investment in our school district over the next ten years. Series 1 of the Bond including approximately $140 million dollars’ worth of work is underway.
The Portrait of a Learner design process engaged our educational system and the broader community - educators, students, elected officials, community members, families - to help build a unifying, collective vision for our students. The 6 C's that make up the TSD Portrait of a Learner seek to tie together the mission, vision, and core values of the district.
The goal of OneTroy is to cultivate an environment of inclusion in our classrooms and schools, ensuring students feel needed and valued, seen and heard, accepted and embraced, while keeping high expectations for all.
This is the moment when it all pays off. Your years here have helped you know who you are, what you want, and how far you want to go. But it’s not only about getting in; it’s about thriving where you are destined to be.
