I&RS/RTI Process

Intervention and Referral Services, I&RS, is a state mandated system to identify and assist struggling students in improving educational outcomes. The committee is a multidisciplinary team, which may include: the building principal or designee, parent/guardian, school counselor, teachers, school nurse, a member of the child study team, and other school personnel. The I&RS team meets regularly to monitor the success of students identified through the referral process, as needing specific academic and/or behavior “interventions” in order to be successful. The I&RS team aids students in the general education program, but also provides support for students determined to be in need of special education programs. 


Willow Grove unitilizes the Response to Intervention Model (RTI).

 Response to Intervention (RTI), is a data- driven, systematic approach to instruction that uses three tiers of research-based strategies and interventions to optimize student growth.  


 Tier 1:  Core Instruction

 All students receive Tier I interventions, also known as “Best Practices” during their core instructional time with their classroom teacher(s).  Tier I instruction is typically successful with 80-90% of the population. 


Tier 2:  Targeted Small Group Intervention 

Approximately 10-15% of students will need supplemental instruction at a Tier 2 level of support to become proficient.  Tier 2 interventions are implemented with groups of students demonstrating common skill deficits or social/emotional/behavioral risk characteristics. The teacher will track the student’s progress over the six to 12 week period.  If  the student continues to have difficulties, then the student will be referred  to the I&RS committee and an Action Plan will be developed.


Tier 3:  Intensive Individualized Instruction 

Students that require additional or more intensive supports than Tier 2 offers will receive Tier 3 intervention.  This may include more frequent, more intensive, and/or one-on-one support during RTI. Typically Tier 3 represents 1-5% of the population. 


The Tiers are flexible in nature.  For example, a student may begin with Tier 3 and

move to Tier 2 as he/she shows progress.
