Matt Ridenour and Josette Rechul have developed the TABS (Tracking Appropriate Behaviours) system, which also features “Positive Behavioural Intervention and Supports (PBIS) tracking,” as well as paperless hall pass technology.

“Every day that I walk into school, I see the need for a system like this,” said Ridenour, co-founder of TABS and a teacher at Crestwood High School in Dearborn Heights, Mich. “Teachers are overwhelmed and they need simple solutions to help monitor students.”

The automatic lock down feature allows secure communication between administration, security and teachers, the founders stated.

Schools interested in using the TABS system for the 2019 school year can email or view video demonstrations at
