As previous posters stated rti is a process that shifts educational resources that are allocated for instructional academic or behavioral interventions. Title 1 funds can help the Title 1 teachers set the goals, assess, monitor progress, and instruct students within the multi-tiered leveling of rti.
--In my school grades 2,4,and 5 use the tiered leveling of the rti model for reading intervention and the other grade level groups use a hybrid type model of rti. All of these group interventions take place during the allocated time when the Title 1 reading teacher is present in the room to assist with the lowest tier group .
The first link has some great ideas and the others helped put things in proper perspective for me.
