Interventions

Every classroom teacher uses a wide variety of interventions on a daily basis.  The RtI model, however, organizes and assesses interventions that are available from the school’s current inventory and identifies which are research-based.  The interventions are then organized into tiers with recommendations on frequency, duration, and intensity.

Research-based interventions have many characteristics that include:

• an experimental design with a large sample size

• an experimental design that is documented in peer-reviewed literature

• a demonstrated correlation between the intervention and student progress

• recommendations for how to deliver the intervention with fidelity

Non-research-based interventions include those that:

• are theoretically driven but have no supporting data

• are based on individual teacher experience but have no supporting data

• have a small sample size (n)

• have no “track record” in peer-reviewed literature

Interventions are applied for the needs of the individual student and are changed as needed throughout the process, based upon collected data.
