## Facts

- Antoine M., a student in the Chester Upland School District, was evaluated for special education after being retained in fourth grade due to significant reading deficits.
- The District provided special education services for roughly fourteen months, then exited Antoine from special education based on passing grades and appropriate behavior.
- Antoine continued to perform poorly on standardized tests; his family obtained an independent educational evaluation in 2004.
- The family placed Antoine in private school for the 2004–2005 year and sought tuition reimbursement; the District denied reimbursement.
- The parents requested an administrative due process hearing seeking findings of denial of a free appropriate public education (FAPE), compensatory education, and tuition reimbursement.
- The hearing officer found Antoine ineligible for special education and applied a one-year limitations period, limiting factual findings largely to December 9, 2003 through April 20, 2005.
- An appeals panel affirmed; the parents filed a federal action challenging the administrative outcome and seeking broad relief, including compensatory education and reimbursement.
- In the federal action, the court addressed a pretrial evidentiary question: whether the parents could introduce additional evidence beyond the administrative record.

## Issues

1. In an IDEA civil action under 20 U.S.C. § 1415(i)(2), when should a district court permit “additional evidence” supplementing the administrative record rather than confining review to that record?

## Decision

- The court granted the parents’ request to supplement the administrative record.
- The court permitted the additional evidence proffered by the parents to be offered at the federal hearing.
- The court emphasized that supplementation must not convert IDEA review into a trial de novo and remains subject to judicial discretion to exclude cumulative or irrelevant material.
- The ruling did not decide IDEA eligibility, denial of FAPE, compensatory education, or tuition reimbursement; it addressed only admissibility of supplemental evidence.

## Legal Principles

- In an IDEA civil action, the court must receive the administrative record and must hear additional evidence at a party’s request, but the court has discretion to limit supplementation to preserve the primacy of the administrative process.
- “Additional evidence” is construed to mean evidence that supplements the record; it does not authorize repeating or embellishing testimony already presented at the administrative hearing.
- A district court should consider admitting non-cumulative evidence when necessary for a full and fair review, including when administrative rulings (such as a limitations determination) constrained the development of relevant historical facts.
- IDEA judicial review is “modified de novo”: the court makes an independent decision based on the preponderance of the evidence while giving due weight to administrative findings.

## Conclusion

The court allowed the parents to present additional, non-cumulative evidence in the IDEA civil action because the administrative proceedings—constrained by a limitations ruling—left an incomplete record for determining the student’s eligibility and related claims, while preserving the court’s gatekeeping role to prevent a de facto retrial.
