Student Registration

O’Fallon Township High School District #203 is excited for the 2025-2026 school year!

O'Fallon Township High School District #203 Skyward login and password information will be emailed to families from incoming feeder schools by June 17, 2025.  The Skyward feeder school login and password will not work for OTHS Skyward accounts. Families with current OTHS upperclassmen must use their previously issued OTHS Skyward login and password to register incoming freshmen.

Registration will be available to all current and incoming feeder school students starting June 25, 2025. Every year, all students must register for O'Fallon Township High School by the first day of school. Only families needing an affidavit to confirm residency or families that need access to a computer will register in person on Tuesday, July 22, 2025, from 12:00 pm to 7:00 pm or on Tuesday, July 29, 2025, from 7:30 am to 2:30 pm at the Smiley campus in rooms 607 and 608. 

Please note that you cannot use a phone to complete registration. If you encounter issues logging in, please contact the computer department at computerdepartment@oths.us or the Smiley main office at (618-632-3507)
