Which students are actually responding to the support layered onto their day, and which aren’t?
That is the question facing district leaders and school principals across the US, who have a bird’s-eye view of dashboards, aggregate scores, trend lines and data points on a daily basis, but can struggle to get to the individual student level.
Failing to answer that question carries a significant systemic weight and – increasingly – a compliance one. Between state math reporting requirements and ESSA’s evidence standards, districts need to show, not just assume, that at-risk learners are getting the right support at the right time (and that there’s a documented record of it).
Rather than taking a wait-and-see approach, a Multi-Tiered System of Supports (MTSS) is designed to catch struggling learners early enough that most can get the support they need “before it snowballs into something complex”, as special education teacher and technology specialist Shira Moskovitz puts it. That early intervention is becoming increasingly important as a growing number of states require MTSS implementation and ESSA places greater emphasis on student support.
The framework runs on a three-tier model, and Tier 2 is where the real decisions happen. This is where intervention groups form, data starts to drive next steps, and schools determine whether a student is ready to step back to Tier 1 or needs to move up to Tier 3. It’s also where most of intervention time and staffing budget ends up.
This article looks at how Mathletics, an evidence-based online math program for Kindergarten to 10th Grade, supports that kind of decision-making at every tier, with most of the emphasis on Tier 2.
For districts weighing where Mathletics fits into their evidence requirements, it’s worth noting that Mathletics has received the ISTE Seal of Approval and is certified under ESSA Level II, with a study finding that students in third through fifth grade who actively used the program outperformed their peers on NWEA MAP® standardized tests.
The three tiers of MTSS and how Mathletics supports each one
TIER 1: Universal instruction
Tier 1 is the instruction every student gets, regardless of where they’re at. Done well, it’s enough on its own for most of a class – something closer to 80–90%, depending on who you ask. This is the prevention layer: catching gaps before they turn into something a small group needs to fix, not cleaning up after the fact.
Mathletics works as a Tier 1 tool by giving every student, not just the ones falling behind, explicit and systematic instruction built around a standards-aligned learning pathway. With 30,000+ activities spanning Kindergarten to 10th Grade, teachers can assign work to the whole class in seconds, and real-time reporting means they don’t have to wait until report cards to see where their students are.
It’s also personalized from the start. A student working ahead and a student working behind can be in the same room, on the same platform, each working at the edge of what they’re ready for – so Tier 1 isn’t a flat, one-size-fits-all baseline, even before anyone needs Tier 2.
Activities, assessments, resources, worksheets for offline learning – all align to state standards across the US, from Common Core adoptions to state-specific frameworks like TEKS in Texas or BEST in Florida.
Tier 2: Targeted support in practice
Smaller in scale than Tier 1 and much bigger in consequence, Tier 2 informs schools whether their interventions are working.
It applies to a handful of students, pulled from the pace of the whole class, working on something a bit more targeted. Whether that time actually closes a gap or just fills a block on the timetable comes down to two things: whether the intervention is aimed at the right skill, and whether anyone’s checking, week to week, if it’s landing.
At College Heights Christian School, that’s the exact problem Mathletics is built to sit inside. Steven Gabrys, the school’s principal, has watched it work at the level of the whole building rather than one classroom:
“The program allows us to meet the needs of diverse learners simultaneously, without them even realizing it. We can challenge gifted students while providing targeted support for those who are struggling.”
Of course, knowing a student needs help isn’t the same as knowing what they need specifically. Mathletics helps solve this gap and target teaching through:
- Diagnosing the actual gap. Assessments are curriculum-aligned and flag the specific skill a student is missing – not “behind,” but behind on this: place value, say, rather than fractions, or the other way round. Two students filed under “struggling with math” can need entirely different groups.
- Grouping students precisely. With just a few clicks, teachers can split a class into up to 12 differentiated groups, each working through its own course and its own sequence of activities, so a group is built around a shared gap rather than a rough guess at who’s behind.
- Sending students back when that’s what’s needed. Where the real problem sits a step or two earlier in the sequence, the Fill Learning Gaps tool moves a student back to that prerequisite concept, rather than pushing them into grade-level content they’re not ready for yet.
- Tracking the group, not just the activity. Comprehensive reporting, including Standards Performance Reporting, shows whether a group is actually closing its target gap, at both the individual and group level – making an immediate check-in possible, rather than letting an error become a bad habit when there is too much time before intervention.
More specifically, the Skill Quest Mastery report shows exactly how each student is progressing through specific quests, while Activity Mastery reports break strengths and weaknesses down by topic – so a teacher isn’t just seeing a score, but knows where to aim the next homework set. A traffic-light system (Learning, Proficient, Mastered) makes it possible to scan a whole group’s standing at a glance, rather than reading raw numbers one student at a time.
- Turning homework into something adjusted, not generic. Assigning a personalized activity takes minutes, which is enough time to set homework matched to what a specific student needs to practice, instead of sending the same worksheet home to everyone.
- Cutting the prep time out of running a group. Ready-to-use resources, built around specific concepts, mean a teacher isn’t building intervention materials from scratch on top of everything else on their plate.
That’s the fade-or-escalate decision at the heart of Tier 2, in practice. A student who starts closing the gap can step back to Tier 1 without a formal meeting or a new label attached to their name, while one who isn’t responding gets flagged early enough that a move to Tier 3 is a planned decision, not a late one.
It also means Tier 2 can absorb more of the work that used to require pulling a student out of the room altogether – which is most of what “inclusive” is supposed to mean.
Tier 3: Intensive support
Tier 3 is the smallest tier by number of students, and the most individual in what it asks of a program. A student here isn’t in a group anymore – the work is built around exactly what they, specifically, are missing, usually alongside a specialist or resource teacher rather than in place.
Mathletics in no way stands in for that specialist. Instead, it gives them support and somewhere to start: activity sequences built around precise skill gaps rather than a fixed grade level, immediate automatic feedback so a struggling student isn’t repeating a wrong strategy for days before anyone catches it.
What’s more, diagnostic data granular enough to show whether the intensity of an intervention is actually matched to what’s happening. Pathways adjust as the student does, so a plan made in September isn’t still being followed, unchanged, in November.
The evidence behind tiered approach to math
39 studies, pooled together in a 2021 meta-analysis published in Exceptional Children, put a number on how much Tier 2 math support actually helps: an effect size of 0.41. That may seem like a small number by the standards researchers use, but it sits comfortably in the range they’d call a practical gain for students struggling with math. Putting the research into real-world terms: It’s the kind of effect a math teacher could notice over the course of a semester.
Some states were building this out well before ESSA gave it a federal home. Kansas is generally credited as one of the earliest to formally adopt the term MTSS, rolling out its own framework years ahead of the 2015 law and landing on close to the same definition ESSA would eventually use.
Other states arrived by different routes – some built out from an existing RTI mandate, some layered a new MTSS framework directly onto Title I improvement planning – and the tier definitions still vary state to state. But the underlying shape holds everywhere: catch a gap early, and let how a student responds decide what happens next.
Mathletics is built to support that same goal, which is why the ESSA Level II certification matters here specifically: it’s evidence that using Mathletics results in measurably better outcomes on standardized math assessments. The ISTE Seal of Alignment, awarded in 2024 and renewed in 2026, adds a second layer of outside validation – this time for digital pedagogy and classroom usability rather than achievement data specifically.
