Beyond the triangle

-by Tim Grivois-Shah, Ed.D.

There comes a moment in every presentation on Response to Intervention (RTI), Positive Behavior Intervention and Supports (PBIS), or Multi-Tiered System of Supports (MTSS) where a slide with a red, yellow, and green triangle appears. It’s time to move beyond the triangle.

Mental models should persist only for as long as they serve the best interests of children and youth.

Feel free to share the video and to contact me at or find me on Twitter at @tgrivoisshah. I’m eager to hear how your team might be thinking of moving ‘beyond the triangle.’
