The Trevlac Online Student Management (TOSM) system is the 4th generation of the Trevlac software. Trevlac went from being a service bureau in the 1970’s serving schools across Canada to a software developer in the early 80’s providing in-house, MS-DOS-based software for schools to manage their students.

The company is proud that one of its major clients has been using either its services or software for over 45 years, and another major client has been using its software for over 30 years.
