What is Response To Intervention? A Practical Guide To Implementing RTI

Response to Intervention is an approach education providers use to help all students. It helps provide increasingly intense levels of targeted intervention for struggling students not making the required progress in the regular education classroom environment.

This article explores what Response to Intervention is and provides practical advice for early identification and implementation of RTI to maximize progress and achievement. We will look in depth at universal screening, high-quality instruction and effective interventions.

What is Response to Intervention?

Response to Intervention (RTI) is a schoolwide process implemented to identify and provide early intervention for students showing academic or behavioral challenges. 

RTI involves a tiered system of support increasing in intensity based on individual student needs.  It emphasizes data-driven decision-making to monitor progress and adjust interventions for each student as needed. It can be implemented across all grade levels, including elementary, middle, and high school. 

While RTI is not a special education program, the data collected throughout the RTI process is used to help identify students with specific learning disabilities (SLD). 

How does Response to Intervention work?

Within the RTI framework, there is a multi-tiered system of support (MTSS) for students based on their individual needs: 

  • Tier 1
  • Tier 2
  • Tier 3 

Tier 1 takes place in the general education classroom.  Teachers keep a close eye on student understanding using effective questioning, formative assessment and summative assessments to identify struggling learners.

Some students then move to Tier 2 of the RTI model. During this phase, students work in small groups, in or outside of the classroom, receiving help with specific skills. 

Students who still struggle after receiving Tier 1 and Tier 2 interventions move to Tier 3.  At this stage, students receive intensive instruction individualized to their specific needs. This may take the form of subject-specific tutoring such as math tutoring

Evidence-based interventions (also called research-based interventions) must be used for students receiving Tier 2 or Tier 3 support.

Response to Intervention relies heavily upon continuous data collection and collaboration among teachers, specialists and parents.

What are the Response to Intervention steps?

While Response to Intervention is a fluid process that occurs throughout the school year, the RTI process typically follows 4 steps: 

1. Universal screening

All students are screened to identify those who need additional support. This screening often involves assessments in key academic areas.

2. Tiered interventions

Each RTI tier provides a different level of intervention intensity.

  • Tier 1: All students receive high-quality, evidence-based instruction in the general education classroom.
  • Tier 2: Students who need additional support beyond regular classroom instruction receive targeted interventions. 
  • Tier 3: Students who continue to struggle despite Tier 2 interventions receive more intensive, individualized interventions or high-dosage tutoring

3. Progress monitoring

Regular assessments help educators monitor the progress of the students 

receiving interventions. This helps determine whether the intervention is effective and if adjustments are needed.

4. Data-based decision making

Data collected during progress monitoring helps inform decisions about whether interventions are continued or modified. A data-driven approach ensures interventions are tailored to individual student needs.

What are the different ways to implement Response to Intervention?

Depending on whether an intervention falls under Tier 1, Tier 2 or Tier 3, the RTI process is implemented differently.  

Here’s how to implement RTI at each tier:

Tier 1: all students

All students receive high-quality, evidence-based instruction in the general education classroom from a general education teacher. Tier 1 focuses on effective teaching practices to meet the needs of the majority of learners.

Tier 2: 10% to 20% of students

Students identified as needing additional support beyond Tier 1 receive targeted interventions. Interventions may involve small group instruction, additional resources, or specific strategies to address challenges. 

Tier 2 intervention examples include:

Tier 3: 1% to 10% of students

Students who continue to struggle after participating in Tier 2 interventions may go on to receive more intensive, individualized support. Tier 3 support may involve specialized, intensive instruction, frequent monitoring, and collaboration with specialists. 

Tier 3 intervention examples include: 

  • personalized learning plans 
  • one-on-one tutoring 
  • specialized behavior intervention plans 
  • individualized counseling
  • structured breaks
  • pull-out groups 

If students’ skills do not make the expected progress with these evidence-based interventions, teachers may refer them for a comprehensive evaluation. This will help to determine a student’s eligibility for special education services under the Individuals with Disabilities Education Act of 2004 (IDEA 2004).

What is the importance of Response to Intervention in education?

Response to Intervention (RTI) is important in education for many reasons:

  • Allows educators to quickly identify and help students who may be struggling in the classroom
  • Applies to both general and special education classrooms
  • Prevents potential over-identification of learning disabilities 
  • Encourages collaboration between educators and families
  • The proactive nature of RTI ensures timely support for students facing academic, behavioral, or social-emotional challenges

What is the teacher’s role in Response to Intervention?

Classroom teachers have a critical role in the implementation of the Response to Intervention process at all levels. 

At Tier 1, teachers are responsible for delivering high-quality instruction in the general education classroom. They may use differentiated teaching strategies to accommodate diverse learning styles and abilities. 

Teachers may also collect data and conduct screenings to identify students who may require additional support. 

During Tier 2 and Tier 3, teachers implement targeted and intensive interventions. Strategies are monitored and adjusted based on the progress monitoring data. 

Communication between the class teacher and parents is essential throughout the RTI process to ensure helpful strategies or solutions about an individual student’s needs are consistent between school and home. 

Throughout the RTI process, class teachers should:

  • keep records of interventions
  • stay informed about up-to-date evidence-based practices through professional development  
  • be culturally sensitive to address diverse student needs

How can data inform intervention?

An essential component of the Response to Intervention (RTI) process is data collection. Teachers use data for quality instruction by analyzing student achievement and adjusting teaching strategies based on individual needs. 

Data collected throughout the RTI process assists all those involved in making decisions at each level of the MTSS. 

The data directly impacts the decision of each student to either maintain or adjust the level of support received. Progress monitoring of Tier 2 and Tier 3 interventions helps to determine which students are responding to the interventions and which ones are not. Precise, continuous data collection from teachers and specialists helps the RTI process be more effective.

Research strongly supports Response to Intervention (RTI) and its evidence-based practices which boosts its credibility. Many studies have explored how effective RTI is, providing valuable insights into its impact on students. 

These studies help improve RTI strategies by making sure they are based on thorough research; this provides further support for schools to provide successful interventions.

What are the benefits of Response to Intervention?

Response to Intervention (RTI) has substantial benefits in education and positively influences student progress and achievement. RTI helps identify at-risk students early on which allows educators to provide personalized interventions tailored to a student’s specific needs. This approach has shown improvements with both academic and behavioral interventions, closing learning gaps and fostering a schoolwide culture that values each student’s success. 

RTI offers flexibility in interventions and promotes collaboration, as well as a data-driven decision-making process. It creates a supportive learning environment in the general education classroom and helps to reduce the over-identification of learning disabilities. Additionally, RTI encourages parent involvement. Inform parents about their child’s progress and actively participate in their education. 

What are the challenges of Response to Intervention?

Although Response to Intervention (RTI) is highly effective, it is not without its challenges: 

  • potential strain on resources as interventions may require extra teachers or interventionists, time, and instructional materials
  • ensuring consistent collaboration among educators, specialists, and parents can be time-consuming and logistically challenging 
  • continuously collecting and analyzing data is time-consuming and adds to teacher’s workload 

However, it is possible to overcome these challenges. Schools can: 

  • allocate sufficient resources and provide professional development for educators to strengthen RTI implementation
  • encourage schoolwide communication and collaboration to help with coordination issues
  • implement a system of regular reassessment and updating of intervention strategies based on ongoing data
  • consider choosing a tuition partner for Tier 3 interventions that ease the pressure of teacher workload by tracking regular assessment and progress data
