How do you get the most impact out of your MTSS efforts? Impact and effort are often competing realities, so it can be a challenge to know how to strategically approach the work. An Impact-Effort Map is a tool you can use to visualize and prioritize tasks when launching your MTSS practice or with any initiative. It's a two-dimensional matrix where impact is plotted against effort in order to identify which tasks should be done now, done later, or delegated.
