For District Leaders & Math Departments

Your bilingual students know more math than their scores show.
XODA reveals what they actually know.

A diagnostic system that separates mathematical understanding from language development stage — so intervention decisions are based on what students know, not how fluently they say it.

The Problem

Your diagnostic tools cannot separate what students know from how they say it.

When a bilingual student answers a math question in Spanish, code-switches between languages, or writes with phonetic spelling, most assessment systems count that as a math error. It is not. XODA reads the math and the language separately — so the right intervention goes to the right student.

The conflation problem

Standard AI assessment systems treat bilingual student responses as monolingual English text. A correct answer in Spanish registers as wrong. The result: students who understand the mathematics are routed into math intervention they do not need.

The intervention cost

Misclassified students receive remediation that does not address the actual gap. Districts spend resources on the wrong support — while the student's genuine need, whether language scaffolding or conceptual reinforcement, goes unmet.

The compliance risk

Texas Education Code §29.051–29.064 and Chapter 89 of the Texas Administrative Code mandate linguistic accommodations in bilingual assessment. A 2024 GAO report found 41 states required federal assistance distinguishing language barriers from learning disabilities.

How It Works

Two signals. One response. No guesswork.

XODA uses a proprietary deterministic system to process student responses — separating mathematical reasoning from second-language development before any output is generated. The two are never conflated.

XODA Diagnostic Output

Student #14 — Fractions unit — Grade 2

Student wrote

"El denominador es el número de abajo"
Translation: The denominator is the bottom number

Mathematical understanding CONFIRMED
Language development stage L1 SUPPORT INDICATED

Recommended action: This student demonstrates mastery of the fraction concept. Route to language development support — not math intervention.

FERPA compliant by design — the architecture makes compliance automatic.

Teacher Experience

No new technology. No new workflow.

XODA integrates into the tools your teachers already use. It does not add complexity — it removes the judgment call that no teacher should have to make in real time.

XODA does not ask teachers to:
  • Learn new grading software
  • Change their assessment format
  • Grade open-ended responses manually
  • Judge in real time whether a response is linguistic or conceptual
  • Translate student writing before evaluation
  • Adopt new student-facing technology
XODA gives teachers:
  • Instant separation of math and language signals per student response
  • Actionable diagnostic output — confirmed, partial, or absent
  • FERPA-compliant records with a full explainable audit trail
  • Integration with Google Forms and Canvas — no new platform
  • Evidence for intervention decisions that holds up to administrative scrutiny
  • A system built by bilingual math educators, for bilingual math educators

Privacy & FERPA

Student data never leaves the building.

XODA is designed from the ground up for Title I district deployment. FERPA compliance is not a setting we enable — it is how the system is built.

Local processing only

Student responses are processed on school hardware. No student text is transmitted to cloud servers or third-party AI services. The system is designed to operate without persistent connectivity.

Explainable audit trail

Every diagnostic output is traceable step by step. Administrators and parents can see precisely why XODA produced a given result — no algorithmic black boxes on the output side.

Documentation available

XODA holds a Data Privacy Sheet and IRB Protocol supporting district adoption. Available to district administrators on request — no waiting period.

Getting Started

Three ways to move forward.

XODA is in active research deployment. We work directly with district leaders and department heads to design a pilot that fits your campus and your students.

Review the documentation

XODA has been validated against expert human adjudication at the reliability threshold established for diagnostic NLP applications, on a U.S. Title I Grade 2–3 corpus. Full methodology, results, Data Privacy Sheet, and IRB Protocol are available to district administrators. Our Trust Center answers the questions your compliance team will ask.
