5.4 Tiered Intervention (MTSS) & Classroom Organizational Formats

Tiered Intervention & Classroom Organizational Formats

Meeting the needs of every elementary reader takes two things: a tiered system that matches the intensity of instruction to the size of each student's need, and a set of classroom organizational formats that let the teacher teach small groups while the rest of the class practices productively. Competency 4 of Subtest 601 asks you to choose formats for specific instructional objectives and to use evidence-based practices for the diagnosis, prevention, and intervention of literacy difficulties.

The Multi-Tiered System of Supports (MTSS) in Literacy

The Multi-Tiered System of Supports (MTSS), often implemented through the Response to Intervention (RTI) framework, is a prevention-focused, data-driven system designed to identify struggling readers early and provide systematically graduated levels of instructional intensity based on continuous progress monitoring.

The Three Tiers of MTSS / RTI

1. Tier 1: Universal Core Reading Instruction:
   • Target Population: 100% of all general education students.
   • Instructional Scope: High-quality, evidence-based, scientifically researched core reading curriculum delivered in an uninterrupted 90-minute literacy block. A robust Tier 1 curriculum should effectively meet the needs of approximately 80% to 85% of the student population without additional supplemental intervention.
   • Key Features: Whole-class explicit instruction combined with differentiated small-group guided reading and flexible workstations. Universal screening occurs three times per year (fall, winter, spring).
2. Tier 2: Targeted Supplemental Intervention:
   • Target Population: Approximately 10% to 15% of students identified by universal screeners or diagnostic assessments as performing below grade-level benchmarks.
   • Instructional Scope: Explicit, systematic small-group instruction targeting specific skill deficits (e.g., consonant blend decoding, reading fluency, vocabulary, or main idea comprehension).
   • Group Size & Schedule: Small, homogeneous groups of 3 to 5 students meeting for 20 to 30 minutes per session, 3 to 5 times per week.
   • Critical Structural Principle: Tier 2 intervention is supplemental to, never a replacement for, Tier 1 core reading instruction! Students must never be pulled out of core reading instruction to receive intervention.
   • Progress Monitoring: Brief, standardized curriculum-based measurement (CBM) probes administered bi-weekly or weekly to evaluate growth toward an established aimline.
3. Tier 3: Intensive Individualized Intervention:
   • Target Population: Approximately 1% to 5% of students who exhibit severe, persistent literacy deficits or who fail to respond adequately to Tier 2 supplemental intervention.
   • Instructional Scope: Highly intensive, explicit, systematic, and multisensory instruction (e.g., Orton-Gillingham based approaches) tailored to individual diagnostic profiles.
   • Group Size & Schedule: Delivered one-on-one or in very small dyads of 1 to 2 students for 45 to 60 minutes daily.
   • Progress Monitoring: Frequent CBM data collection (weekly or twice weekly) plotted on progress monitoring charts to guide immediate instructional modifications.
   • Special Education Link: If a student demonstrates insufficient responsiveness despite sustained, high-fidelity Tier 3 intervention, the MTSS team initiates a comprehensive multidisciplinary evaluation to determine eligibility for special education services under IDEA (e.g., Specific Learning Disability / Dyslexia).

Classroom Organizational Formats for Literacy Instruction

Effective literacy teachers utilize a variety of organizational structures to provide balanced, comprehensive instruction throughout the literacy block:

1. Guided Reading

In guided reading, the teacher meets with small, homogeneous, flexible groups of 4 to 6 students reading at the same instructional reading level. The teacher introduces a leveled text, activates prior knowledge, and sets a reading purpose. Students read the text independently and quietly—often using whisper-reading in early grades. The teacher listens in, observes reading behaviors, takes running records, and provides immediate coaching at points of difficulty ('Look at the beginning of that word; what sound does that chunk make?'). Guided reading groups are dynamic and flexible, changing frequently as assessment data reveals shifting needs.

Instructional Warning: Avoid round-robin reading (where students take turns reading paragraphs aloud unannounced while the class follows along) and popcorn reading. These practices induce severe anxiety, offer negligible reading practice (a student reads for only 30 seconds out of a 20-minute lesson), model disfluent reading, and undermine comprehension.

2. Literature Circles

Literature circles are student-centered, collaborative inquiry groups where small, heterogeneous groups of students read and discuss the same book or text. Unlike teacher-directed guided reading, literature circles are peer-led, fostering critical analysis and academic discourse. Students assume structured, rotating roles to guide their discussions:

• Discussion Director: Develops open-ended, higher-order questions that prompt rich conversation, debate, and personal reflection.
• Literary Luminary / Passage Master: Selects memorable, significant, or puzzling passages to read aloud and analyze with the group.
• Connector: Bridges connections between the book and real life, other texts, or historical/contemporary world events (text-to-self, text-to-text, text-to-world).
• Vocabulary Enricher / Word Wizard: Identifies unfamiliar, intriguing, or critical vocabulary words to define, analyze, and explore in context.
• Summarizer / Illustrator: Synthesizes key plot developments or visualizes major themes through graphic representations and summary charts.

3. Reading and Writing Workshop

The workshop model provides an instructional architecture divided into three predictable segments:

1. Mini-Lesson (10–15 minutes): Explicit whole-group teacher modeling of a specific reading comprehension strategy, literary craft move, or grammatical convention through direct explanation and think-aloud.
2. Independent Practice & Conferring (35–45 minutes): Students read authentic self-selected books or work on writing drafts. During this time, the teacher conducts individual student conferences or pulls small guided reading groups.
3. Share / Debrief (5–10 minutes): The class reconvenes to share how they applied the target mini-lesson strategy, reflecting on breakthroughs and setting goals.

4. Literacy Centers and Workstations

While the teacher instructs small guided reading groups, the remaining students engage in independent or partner learning at literacy workstations. High-leverage workstations include:

• Word Work Station: Manipulating magnetic letters, sorting word cards by phonics/morphological patterns, exploring prefixes/roots.
• Fluency Station: Reading paired poetry scripts, whisper-phone reading, recording oral reading on digital devices for self-evaluation.
• Listening Center: Listening to professional audiobooks while tracking print in trade books to build listening comprehension and vocabulary.
• Writing Lab Station: Composing responses to literature, engaging in free-writing, or revising drafts using peer revision protocols.

5. Individual Conferring

Conferring is one-on-one differentiated instruction occurring during independent workshop time. A conferring session typically lasts 3 to 5 minutes and follows a structured architecture:

• Research: The teacher observes the student, asks open-ended questions ('What are you working on as a reader today?'), and reviews their current work.
• Compliment: The teacher names and affirms a specific, successful strategy the student is using.
• Teach: The teacher introduces one explicit, targeted next step or skill, modeling how to apply it.
• Goal-Setting: The student commits to trying the strategy independently, and the teacher records anecdotal notes to follow up in the next conference.

6. Multiage and Flexible Groupings

Some schools use multiage groups, which combine students from two or more grade levels, for literacy blocks or intervention. Group by current skill need, not age, and regroup often as progress-monitoring data change. A multiage decoding group, for example, might include a strong second grader and a struggling fourth grader who need the same vowel-team lesson. Keep the content respectful of each student's age, using decodable texts and topics that do not feel babyish to older students.

Worked Analysis Example: MTSS Data-Based Decision Making

Student Context and Screening Data

A second-grade student, Lucas, scores in the 12th percentile on the fall universal reading screener (DIBELS Oral Reading Fluency), reading only 18 words correct per minute (WCPM) against a grade-level benchmark of 52 WCPM. A diagnostic phonics survey indicates severe deficits in decoding consonant blends, vowel digraphs, and silent-e words.

Intervention Design and Progress Monitoring

1. Tier 1: Lucas receives the daily 90-minute core reading block with differentiated whole-class instruction.
2. Tier 2 Placement: The intervention team places Lucas in a targeted Tier 2 small group (4 students) receiving 30 minutes of explicit, systematic phonics intervention 4 days per week using an evidence-based multisensory program.
3. Aimline Calculation: To reach the mid-year benchmark of 72 WCPM in 16 weeks, Lucas must gain approximately 3.4 words per week (Aimline slope = (72 - 18) / 16 = 3.38 WCPM/week).
4. Progress Monitoring Tracking: The interventionist collects weekly 1-minute CBM oral reading fluency probes. After 8 weeks, the team plots Lucas's scores:
   • Week 1: 18 WCPM
   • Week 2: 19 WCPM
   • Week 3: 21 WCPM
   • Week 4: 20 WCPM
   • Week 5: 22 WCPM
   • Week 6: 21 WCPM
   • Week 7: 23 WCPM
   • Week 8: 22 WCPM

Data-Based Decision Rule Analysis

• Observation: Over 8 weeks, Lucas gained only 4 WCPM (an average growth rate of 0.5 WCPM/week). Lucas's progress monitoring trend line falls dramatically below the target aimline (which called for 45 WCPM by Week 8).
• Decision: MTSS data decision rules dictate that when four consecutive data points fall below the aimline despite high-fidelity Tier 2 implementation, instruction must be changed or intensified. Lucas is non-responsive to Tier 2 small-group intervention.
• Action: The team moves Lucas to Tier 3 Intensive Intervention:
  • Reduce group size to 1:1 or 1:2.
  • Increase session time to 45 minutes daily.
  • Implement a highly specialized, explicit Orton-Gillingham multisensory decoding curriculum.
  • Increase progress monitoring frequency to twice weekly.
  • If non-responsiveness persists after 8 additional weeks, initiate a formal multidisciplinary special education evaluation.

Authentic Classroom Scenarios

Scenario 1: Structuring Literacy Workstations During Guided Reading

A third-grade teacher needs to instruct three 20-minute guided reading groups daily without classroom interruptions. To achieve this, the teacher spends the first three weeks of the school year explicitly modeling and practicing literacy workstation routines. Students rotate through four stations: Word Work (sorting vowel teams), Listening Center (tracking audiobooks), Writing Lab (composing responses to open-ended reading prompts), and Independent Reading. The teacher teaches a 'Three Before Me' rule (consult three peers or classroom anchor charts before interrupting the teacher at the guided reading table). As a result, 20 students work productively and independently while the teacher delivers uninterrupted, targeted instruction.

Scenario 2: Fourth-Grade Literature Circle with Accountable Talk

A fourth-grade class reads Katherine Applegate's The One and Only Ivan. During their weekly literature circle meeting, five students gather in a circle with their books and role sheets. The Discussion Director opens: "Why do you think Ivan didn't express his anger for so many years?" The Connector responds using an accountable talk stem: "I agree with the idea that he suppressed his feelings to protect himself, and I'd like to connect that to how humans sometimes stay quiet when they feel powerless." The Literary Luminary then directs the group to a passage that uses short, one-sentence paragraphs and asks how that choice reflects Ivan's emotional isolation. The teacher observes and takes anecdotal notes on academic discourse without intervening, supporting student-led inquiry.
