the first of its kind, the concept of the CSSU was
born during a hacking competition between two grade nine
students at Crescent, to see who could programmatically
retrieve their marks from Crescent's online markbook.
In December 2012, just a few weeks after that fateful hacking competition, Jonathan Libby began writing the first version of the Crescent School Student Utility. After a few failed attempts and plenty of sleepless nights, the Student Utility has become a staple of Upper School life and is used by more than three quarters of Crescent's Upper School students.
|Students in Crescent Upper School||~360|
