The Integrated Multi-Tiered System of Supports (iMTSS) is a comprehensive framework used in education to provide targeted support to all students both academics and behaviors. This system is often depicted as a pyramid with three tiers, where Tier 1 represents universal instruction for all students, Tier 2 provides targeted interventions for students who need additional support, and Tier 3 offers intensive interventions for students with significant needs. This blog post will focus on Tier 2, its importance, and how it aligns with the science of reading best practices, supported by relevant research.

The Importance of Tier 2

1. Early Identification and Intervention: One of the primary goals of Tier 2 is to identify and support students who are at risk for academic difficulties early on. Research shows that early intervention is crucial for preventing long-term academic struggles. According to the National Reading Panel (2000), early reading interventions are significantly more effective than later remediation. By providing targeted support at the first sign of difficulty, educators can help prevent small issues from becoming significant obstacles.

2. Preventing the Matthew Effect:  The Matthew Effect, coined by Stanovich (1986), refers to the phenomenon where "the rich get richer and the poor get poorer" in terms of reading skills. Students who start with strong reading skills tend to improve at a faster rate, while those with weak skills fall further behind. Tier 2 interventions are designed to prevent this effect by giving struggling readers the support they need to catch up with their peers.

3. Efficient Use of Resources:  Tier 2 allows for a more efficient use of educational resources. By providing targeted interventions to small groups of students, schools can address learning gaps without overburdening the system. This targeted approach ensures that students receive the help they need without requiring the more intensive and resource-heavy supports of Tier 3.

What Tier 2 Is Not

Tier 2 is not simply reteaching Tier 1 instruction in the same way or increasing the time a student spends on general curriculum without adjusting how it’s delivered. According to Fuchs, Fuchs, and Compton (2012), effective Tier 2 instruction must be more explicit, more systematic, and more intensive than what students receive in the general education setting. It’s not a “wait and see” model where students are passively monitored—nor is it one-size-fits-all instruction. A student who struggles in Tier 1 needs targeted intervention that directly addresses their unique learning gaps, not just extra exposure to the same material that didn’t work the first time.

Additionally, Tier 2 is not special education or an automatic path to an Individualized Education Program (IEP). The purpose of Tier 2 is to prevent the need for more intensive services by addressing difficulties early and efficiently. IDEA 2004 encourages schools to use scientifically based interventions and progress monitoring as part of the evaluation process, but Tier 2 should never delay a referral to special education when appropriate. Tier 2 must be timely, data-driven, and carefully implemented to be effective—and should not be mistaken for a permanent placement or used as a gatekeeper for accessing special education services.

How Tier 2 Ties into the Science of Reading Best Practices

The science of reading is a body of research that encompasses what is known about how people learn to read. This research has led to evidence-based practices that are effective in teaching reading. Tier 2 interventions, when aligned with these best practices, can significantly enhance reading outcomes for students.

1. Explicit and Systematic Instruction: The science of reading emphasizes the importance of explicit and systematic instruction in foundational reading skills, such as phonemic awareness, phonics, fluency, vocabulary, and comprehension. Tier 2 interventions often focus on these areas, providing students with clear, direct teaching and practice opportunities.

Research Support: A study by Foorman et al. (2016) found that explicit instruction in phonemic awareness and phonics leads to significant improvements in reading outcomes for struggling readers.

2. Data-Driven Decision Making: Effective Tier 2 interventions rely on ongoing assessment and data analysis to identify students' needs, monitor progress, and adjust instruction as necessary. This data-driven approach ensures that interventions are tailored to each student's specific strengths and weaknesses.

Research Support: The use of curriculum-based measurement (CBM) has been shown to be effective in monitoring student progress and guiding instruction. Fuchs and Fuchs (2006) highlighted the importance of frequent progress monitoring in ensuring the success of interventions.

3. Small Group Instruction: Tier 2 interventions typically involve small group instruction, which allows for more personalized and intensive support. Small groups enable teachers to provide more immediate feedback and to differentiate instruction based on individual student needs.

Research Support: Wanzek and Vaughn (2007) found that small group reading interventions are more effective than whole-class instruction for students with reading difficulties, particularly when the groups are kept to a manageable size.

4. Multisensory Approaches: The science of reading supports the use of multisensory approaches, which engage multiple senses to reinforce learning. This can include visual, auditory, and kinesthetic-tactile activities that help students connect sounds to letters and words.

Research Support: Multisensory teaching methods, such as those used in the Orton-Gillingham approach, have been shown to be effective for students with dyslexia and other reading difficulties (Ritchey & Goeke, 2006).

Implementing Tier 2 Interventions

Effective implementation of Tier 2 interventions requires careful planning and ongoing evaluation. Here are some key steps:

1. Screening and Identification: Universal screening is essential for identifying students who may need Tier 2 support. Screening tools should be reliable and valid, and they should be administered regularly to catch issues early.

2. Designing Interventions: Interventions should be evidence-based and tailored to address the specific needs identified through screening and assessment. They should include explicit, systematic instruction in foundational reading skills and incorporate multisensory teaching methods where appropriate.

3. Progress Monitoring: Regular progress monitoring is crucial for assessing the effectiveness of interventions and making necessary adjustments. This involves frequent, brief assessments that provide data on student progress and inform instructional decisions.

4. Professional Development: Teachers need ongoing professional development to stay current with the latest research and best practices in reading instruction. This training should include strategies for delivering Tier 2 interventions and using data to guide instruction.

5. Family Involvement: Engaging families in the intervention process can enhance student outcomes. Parents and caregivers can support reading development at home through activities that reinforce skills being taught in school.

Challenges and Solutions

Implementing Tier 2 interventions can present challenges, but with thoughtful planning and collaboration, these can be overcome.

1. Resource Limitations: Schools may face limitations in staffing, time, and materials for Tier 2 interventions. Solutions include leveraging existing resources, such as paraprofessionals and volunteers, and seeking grants or other funding opportunities.

2. Fidelity of Implementation: Ensuring that interventions are implemented with fidelity is critical for their success. This requires ongoing training, supervision, and support for teachers, as well as regular observation and feedback.

3. Balancing Interventions with Core Instruction: It's important to ensure that Tier 2 interventions supplement, rather than replace, core instruction. This requires careful scheduling and coordination to ensure that students do not miss out on essential classroom learning.

Tier 2 interventions are a vital component of the iMTSS framework, providing targeted support to students who are at risk for academic difficulties. By aligning these interventions with the science of reading best practices—such as explicit and systematic instruction, data-driven decision making, small group instruction, and multisensory approaches—schools can significantly improve reading outcomes for struggling readers. Ongoing assessment, professional development, and family involvement are essential for the successful implementation of Tier 2 interventions. With the right support in place, all students can achieve reading success and reach their full potential.
