Tennessee RTI2 Tiers 2 and 3: What Your Child Should Be Receiving
If the school tells you your child is in "Tier 2" or "Tier 3," those words mean something specific. They're not just labels for how much help a student needs—they describe a defined level of intervention with requirements for how it's delivered, how often, in what group size, and how progress is tracked. When those requirements aren't met, the intervention data isn't reliable, the child isn't getting what they need, and the RTI2 process breaks down.
Tennessee adopted RTI2 in 2014, and the state has published guidelines on what each tier should look like. Here's what your child should actually be receiving at Tier 2 and Tier 3—and the questions to ask when something seems off.
Tier 1: The Baseline Everyone Receives
Before looking at Tiers 2 and 3, it helps to understand Tier 1, because RTI2 is a tiered system—each level builds on the last. Tier 1 is high-quality, evidence-based instruction delivered to all students in the general education classroom. Three times per year, schools conduct universal screening (typically using tools like STAR Reading or AIMSweb) to identify students who are performing below grade-level benchmarks.
Students who screen below the cut point—meaning their score suggests they're at risk—are flagged for additional support. How far below benchmark they are, and for how long, typically determines whether they're placed in Tier 2 or referred directly to Tier 3.
RTI2 works only when Tier 1 instruction is actually high quality. If most students in a classroom are struggling, the problem may be Tier 1 delivery, not individual student deficits. This is called a "class-wide problem" and should trigger a review of core instruction before placing dozens of students in intervention groups.
Tier 2: Targeted, Small-Group Intervention
Tier 2 is supplemental to—not a replacement for—Tier 1 instruction. Students in Tier 2 still receive all their regular classroom instruction and then receive additional targeted support on top of it.
What Tier 2 should look like in Tennessee:
Group size: 3 to 5 students. Groups should be homogeneous—students with similar skill deficits working on the same targeted skills. A group of 10 is not Tier 2; that's small-group instruction that doesn't meet the RTI2 standard.
Frequency and duration: 3 to 5 sessions per week, 20 to 30 minutes per session. This is additional time beyond the regular literacy or math block—not carved out of it. If the Tier 2 intervention is happening instead of classroom instruction rather than in addition to it, that's a fidelity problem.
Intervention program: The program must be evidence-based and specifically matched to the student's deficit area. "Extra reading time" or "reviewing worksheets with a paraprofessional" is not a Tier 2 intervention. A structured literacy program like Wilson Reading System, Barton, or RAVE-O applied with fidelity is. Ask the school specifically what program is being used and ask to see the program manual.
Duration of a Tier 2 cycle: Typically 8 to 12 weeks before the team formally reviews data. At the end of a cycle, the team looks at progress monitoring trends and decides: Has the student responded adequately? (Exit Tier 2, return to Tier 1 monitoring.) Is progress acceptable but slow? (Continue Tier 2.) Is progress insufficient? (Consider Tier 3 or evaluation referral.)
Progress monitoring: At minimum, every two weeks. This means brief, standardized probes (like CBM oral reading fluency or math computation probes) administered consistently and recorded over time to show a growth trend. If the only data you've seen is quarterly report card grades, they're not doing progress monitoring.
What to Ask at Tier 2 Team Meetings
When the school brings you in to discuss your child's Tier 2 progress, ask:
- What specific intervention program is being used?
- Is the group size 3-5 students? Who are the other students in the group?
- How many minutes per week is my child receiving this intervention, and is it in addition to regular classroom instruction?
- Who is delivering the intervention—a certified teacher or a paraprofessional? (Paraprofessionals can deliver some interventions, but they should be supervised by a certified teacher and following a structured protocol.)
- What does the progress monitoring data show? Can I see the graph?
- How does my child's growth rate compare to grade-level peers?
You are entitled to this information. If the school can't answer these questions, that's relevant information about fidelity.

Tier 3: Intensive, Individualized Intervention
Tier 3 is the most intensive level within RTI2 and is the stage most commonly referenced when schools are considering whether to refer a student for special education evaluation. It should not be confused with special education itself—Tier 3 is a general education intervention, not an IEP service.
What distinguishes Tier 3 from Tier 2:
More individualized: Tier 3 interventions are tailored specifically to the individual student's deficit profile, not just the group's general area of weakness. The intervention plan should reference the student's specific assessment data.
Smaller group or 1-on-1: Tier 3 is typically delivered individually or in groups of no more than 2-3 students. If your child is in a "Tier 3 group" of 6, that's not Tier 3.
Higher frequency and intensity: 5 sessions per week, 45 to 60 minutes per session in many implementations. The additional time requirement is what makes Tier 3 genuinely intensive—a student receiving 30 minutes three times per week hasn't had their intervention intensity doubled from Tier 2.
Delivered by trained specialists: Tier 3 should typically be delivered by an interventionist, reading specialist, or special education teacher—someone with specific training in intensive intervention delivery. Paraprofessional-delivered Tier 3 with minimal specialist oversight is a fidelity problem.
Weekly progress monitoring: Unlike Tier 2's biweekly monitoring, Tier 3 should be monitored weekly. The data sensitivity needs to be higher because decisions are being made more frequently and the stakes are higher.
Duration before evaluation discussion: A student who has been in Tier 3 for 8-16 weeks with insufficient progress has accumulated the data that supports an evaluation referral. Some Tennessee schools use this window to finally initiate a referral. Others try to run additional Tier 3 cycles indefinitely. That pattern—repeatedly extending Tier 3 without a referral—is a common form of RTI2 delay, and parents can interrupt it at any point with a written evaluation request.
When Tier 3 Should Trigger an Evaluation Conversation
Tennessee guidance is clear that persistent non-response at Tier 3 is an indication that special education evaluation should be considered. This doesn't mean a parent has to wait for the school to make that call. A parent can request evaluation at any time, and a student's Tier 3 status actually provides supporting documentation for the request.
If your child has been in Tier 3 for more than one semester without adequate response—and without the school initiating an evaluation referral conversation—it's reasonable to put your evaluation request in writing. The RTI2 data your child has accumulated is exactly the kind of pre-evaluation documentation that supports the eligibility process.
The Tennessee IEP & 504 Blueprint covers how to write an evaluation request that references Tier 3 data and what the 60-day evaluation timeline looks like from the point of parental consent.
Reading RTI2 Progress Monitoring Data
Progress monitoring charts show a student's actual performance (data points) against an expected growth line (the aim line or goal line). Here's how to read them:
- Data points above the aim line: The student is on track or exceeding expectations. This is a positive response to intervention.
- Data points consistently below the aim line: The student is not keeping pace with expected growth. If 3-4 consecutive data points fall below the aim line, most RTI2 guidelines call for a change—either adjusting the intervention or moving to the next tier.
- Flat trend line: The student is not growing at all, or is making negligible gains regardless of intervention. This is the clearest indicator of insufficient response.
- Variable data points with no consistent trend: The data may reflect inconsistent implementation, frequent absences, or genuine day-to-day variability. It's harder to interpret.
Ask to see your child's progress monitoring graph at every RTI2 team meeting. If the school doesn't have a graph—if they're describing progress verbally without showing you the data—ask specifically for the graphed progress monitoring data and the aim line.
What Legitimate RTI2 Is Not
This is worth stating plainly:
- Sitting with a paraprofessional reviewing homework is not RTI2 intervention.
- Doing an extra 20 minutes of the same reading curriculum used in class is not targeted supplemental intervention.
- Being pulled out of recess to do extra worksheets is not evidence-based intervention.
- Getting "extra help" from a teacher after school on an informal basis is not RTI2.
RTI2 has specific structural requirements. When those requirements aren't met, the intervention isn't RTI2—it's well-intentioned support that happens to carry the RTI2 label. The label matters because it's being used to justify delaying evaluation and make decisions about special education eligibility.
When you're asking the school about your child's tier placement, ask about the substance—the program, the group size, the frequency, the data—not just the tier label. That's where you'll find out whether what's happening is actually RTI2 or whether it just has the right name.
