The Delta Math RtI Program was developed to help educators identify students not ready to learn current math standards. 

In 2007, the Ottawa Area ISD began developing screening and reporting tools to support the implementation of math RtI for its local schools.  Soon after, schools in other regions chose to use Delta Math online readiness screeners, data reports and other program resources to meet their needs. 

In 2010, the Michigan's Integrated Mathematics Initiative identified Delta Math as a promising practice and has been supporting the development of implementation resources.  Currently, this support is focused on the development of Tier 2 intervention lessons for each Delta Math readiness standard.

We would like to offer special thanks to the support and feedback provided by consultants from the following agencies: Allegan AESA, Alpena-Montmorency-Alcona ISD, Bay-Arenac ISD, Berrien RESA, Gratiot-Isabella RESD, Kalamazoo RESA, Oakland Schools, St. Joseph County ISD, Traverse Bay Area ISD and the Michigan’s Integrated Mathematics Initiative.
