Research based math intervention programs and the evidence based math intervention a school can defend

Your plan needs a program with an ESSA rating, and your interventionists need to know why each student is still stuck. Those are two purchases. Coeducate is the second one: an AI tutor that reads the student's reasoning and names the idea that broke. Paste an answer into the panel to try it.

The short answer

What makes a math intervention program research based

A research based math intervention program is one where a study of that program, in your grade band, found that students who used it did better than students who did not. Under the Every Student Succeeds Act the study design sets the tier: strong, moderate or promising. Evidence for ESSA currently lists 53 math programs that reach one of those three tiers.

Coeducate is not one of them. It has no efficacy study and no ESSA tier, and this page says so in every section where it matters. What it sells is the part a rated program leaves open: a dated, per-skill record of why each student in the intervention block got the item wrong.

Counts from the math listing on Evidence for ESSA.

01 What the law asks for

Evidence based math intervention programs by ESSA tier

The definition sits in section 8101(21)(A) of the law, and the Institute of Education Sciences summarizes it in its ESSA tiers of evidence handout. The tier describes how the program was studied. It is not a quality score for the lessons.

1

Strong

At least one well-designed experimental study (a randomized controlled trial) with a positive, significant effect.

Section 1003 plans accept it.

2

Moderate

At least one well-designed quasi-experimental study, with comparison groups matched at baseline.

Section 1003 plans accept it.

3

Promising

At least one correlational study that controls statistically for selection bias.

Section 1003 plans accept it.

4

Demonstrates a rationale

A logic model built on high-quality research, plus a study of the program that is planned or under way.

Section 1003 plans do not accept it.

Two details catch buyers out. A rating belongs to the grades in the study, so a program that is strong in grades 3 to 5 has no rating in grade 7 unless another study covers it. And ratings move: when a newer study finds no effect, the listing changes. Check the date on whatever the vendor sends you.

02 Check the claim yourself

Three places to verify a research based math intervention before you sign

1

Evidence for ESSA

Run by Johns Hopkins. Filters by grade, by struggling students and by rating. Fastest way to see whether a program has a tier at all.

Does it list the program for my grades?

2

What Works Clearinghouse

The federal reviewer. Intervention reports rate the studies behind a named program, and practice guides rate teaching practices rather than products.

Did the studies meet standards?

3

NCII tools chart

The National Center on Intensive Intervention reviews studies of intervention programs for students with intensive needs, with effect sizes by subgroup.

03 The gap a rating leaves

A strong rating is an average, and your student is not one

An ESSA rating says the group that used the program outscored the group that did not. Inside that group some students gained a lot and some gained nothing. The study cannot tell you which of your students will be in the second set, and neither can the program's dashboard, which reports minutes, lessons passed and a score.

That is where intervention time goes missing. A student who is not responding to a rated program needs someone to look at how they reasoned. The Tier 3 math intervention programs page covers that diagnostic step for intensive cases, and the elementary math intervention programs page sets the tutor against the six practices the What Works Clearinghouse rates as strong evidence.

Purchase one

The rated program

  • Carries the ESSA tier your plan cites
  • Supplies the lesson sequence and the practice volume
  • Reports usage and a score per student
  • Answers: did the group improve?

Purchase two

The diagnosis layer

  • Carries no tier and does not pretend to
  • Works on the items from your rated program or core unit
  • Reports the misconception, in the student's own words
  • Answers: why is this student not improving?

How schools put the two on one plan

The rated program is named as the evidence-based intervention. Coeducate is listed under progress monitoring and documentation, paid from the general or Title I, Part A budget, at a published price.

04 Example output

One grade 6 ratio answer the dashboard scored as simply wrong

Where the student is

Twelve weeks on a strong-rated adaptive program, 40 minutes a week as prescribed. Ratio unit score has not moved.

The item and what the student wrote

A recipe uses 2 cups of flour for every 3 cups of milk. How much flour for 9 cups of milk? "8. Milk went up by 6 so flour goes up by 6."

The program kept serving easier ratio items, and the student kept adding. Nothing in a usage report shows that. One session with the tutor does, and the reteach it writes is about multiplying both quantities, which no amount of extra practice at a lower level would have reached.

Session evidence card, grade 6, ratios and proportional reasoning

Fixed example

Diagnosis

Compares ratios by adding the same amount instead of multiplying

The student sees milk change from 3 to 9 as plus 6 and applies plus 6 to the flour. Asked what happens with 6 cups of milk, the student said 5 cups of flour, the same additive step. The strategy is consistent across items, so this is a concept gap about what a ratio keeps constant.

Next tutoring move / hint only

If 3 cups of milk need 2 cups of flour, how many batches is 9 cups of milk? What happens to the flour in each batch?

Teacher note

Facts are fine, so more fact practice will not help. The student needs to see a ratio as batches. Reteach with a ratio table before the next program session.

Reteach in 5 minutes

Ratios as batches, not differences

  1. Build one batch with two flour counters and three milk counters, then lay out three batches.
  2. Fill a ratio table for 3, 6 and 9 cups of milk and ask what each row was multiplied by.
  3. Give two new contexts and ask for the number of batches before any computing.

06 Before the purchase order

Six questions to put to any evidence based math intervention vendor, with our answers

Question 1

Which study earns the tier, and who ran it?

Coeducate. None. There is no study of Coeducate and no tier.

Question 2

Which grades and student groups were in it?

Coeducate. Not applicable. The tutor is built for grades 3 to 12.

Question 3

What dosage did the study use, and can we staff it?

Coeducate. No prescribed dosage. Sessions are untimed and fit inside the block you already run.

Question 4

What does a teacher see when a student is not responding?

Coeducate. A dated card per session that names the misconception, quotes the student and writes a three-step reteach.

Question 5

Is the price public, and what happens at renewal?

Coeducate. Yes. $89 a month, $3,480 a year per school, $1,290 a month per district, on the pricing page.

Question 6

What happens to student work?

Coeducate. It is never used to train models. Records can be exported as CSV and deleted.

07 Being straight about it

When you should buy a rated program and not this

  • The plan names one intervention and it must carry a tier. Choose from Evidence for ESSA or the NCII chart. Coeducate cannot be that line.
  • You have no intervention curriculum at all. The tutor works on items you bring. It does not supply a sequence of daily lessons.
  • Your students are in kindergarten to grade 2. The tutor reads written reasoning, so it starts at grade 3. Number Rockets and Whole Number Foundations are rated for the early grades.
  • The need is fact fluency. The tutor is untimed on purpose. A timed fluency routine is a different tool.

08 Who buys it

The people who sit between the research and the classroom

Federal programs director

Already funded a rated program and now has to show the plan is being monitored student by student.

MTSS coordinator

Runs the decision meetings and wants a reason next to every flat graph, exported to the team tracker.

Math interventionist

Has 30 students on the rated program and no time for error analysis. The math intervention software page shows a middle school week.

Principal with a building budget

Wants a published number and a clear privacy answer. See AI tutor for schools pricing and the student data and COPPA page.

09 FAQ

Questions buyers ask about research based math intervention programs

Buying for older students? The high school math intervention programs page covers Algebra 1 support, and the i-Ready alternative for schools page compares a rated diagnostic with the tutor row by row.

What are research-based math interventions?

Research-based math interventions are programs or practices whose effect on student math outcomes has been tested in studies, not only described by the vendor. In US schools the working standard is the Every Student Succeeds Act, which sorts evidence into four tiers: strong, moderate, promising, and demonstrates a rationale. A program counts when a study of that program meets one of them.

What is the difference between research-based and evidence-based math intervention programs?

Research-based usually means the program was designed from published research on how students learn math. Evidence-based means the program itself was studied and students who used it did better than students who did not. ESSA uses the second meaning. A vendor can honestly call a product research-based and still have no study that earns an ESSA tier.

What is the best research-based math intervention program?

There is no single best program, because ratings apply to specific grades. On Evidence for ESSA, strong-rated math programs include Zearn Math for grades 1 to 8, DreamBox Math for kindergarten to grade 5, ST Math for grades 3 to 6, ASSISTments for grades 7 and 8, and Saga Math tutoring for grades 9 and 10. Start from the grade band and the students you serve.

How do I know if a math intervention program is evidence-based?

Look the program up in three independent places: Evidence for ESSA, the What Works Clearinghouse, and the National Center on Intensive Intervention tools chart. Check that the rating covers your grade band and student group, then ask the vendor for the study itself. A logic model or a white paper written by the vendor is not a rating.

Is i-Ready a research-based intervention?

Yes, with limits. Evidence for ESSA lists i-Ready Personalized Instruction Math with a moderate rating for grade 5 and i-Ready Classroom Mathematics with a moderate rating for grades 3 to 5. Moderate is ESSA Tier 2, which qualifies for school improvement funding. The rating does not automatically extend to other grades, so check the band you plan to buy for.

Is IXL evidence-based?

Yes. Evidence for ESSA lists IXL Math with a strong rating for grades 3 to 5. That rating comes from a study of IXL as a practice program in those grades. It says students who used it scored higher. It does not say the SmartScore tells a teacher why a particular student is stuck, which is a separate question.

Do Title I funds require evidence-based interventions?

School improvement funds under Section 1003 of ESSA do: interventions in a comprehensive or targeted support plan must meet the strong, moderate or promising tier. For general Title I, Part A spending, a district has more room, and the fourth tier can qualify in many states. Your state ESSA plan and federal programs office set the rule that applies to you.

How much do research-based math intervention programs cost?

Rated programs are mostly sold by quote. District documents show about $2,500 per school for Zearn, $20 to $28 per student for DreamBox and roughly $10,000 per large site for ST Math. Coeducate has no ESSA rating and publishes its price: $89 a month for one teacher, $3,480 a year for a school of up to 600 students.
