K.C., a minor, by and through her parents S.W.C. and K.A.C. (K.C.) appeals from the district court’s final judgment in favor of the School Board of Collier County (Board). Pursuant to the Individuals with Disabilities Education Act, 20 U.S.C. § 1400 et seq. (IDEA), and corresponding Florida laws, Fla. Stat. § 230.23(4)(m); Fla. Admin. Code Ann. r. 6A-6.0311, the Board is required to provide K.C. with a free appropriate public education (FAPE). In order to achieve an “appropriate” education, the school and parents develop an individualized education program (IEP) together. Either party may request a due process hearing if they cannot agree on the contents of the IEP. Pursuant to Fla. Stat. § 230.23(4)(m)(5), the due process hearing is conducted by an administrative law judge (ALJ) from the Division of Administrative Hearings of the Department of Management Services. In the present case, the district court vacated the ALJ’s decision in favor of K.C. On appeal, K.C. argues the district court erred by (1) allowing the Board to supplement the record with expert testimony, (2) denying KC.’s request to utilize an expert witness, and (3) vacating the ALJ’s decision.
I Background
We briefly review the facts, which are thoroughly documented in nearly eighty pages of findings by the ALJ and well summarized by the district court.
Since KC. began attending Collier County Public Schools, she has been classified as an “exceptional student” with learning disabilities. Accordingly, the Board must provide “special instruction, classes, and services.” Fla. Stat. § 230.23(4)(m)(2). For example, in preparation for KC.’s transition to the fifth grade, the Board acquired a special portable classroom and had it customized to meet K.C.’s special needs. Because KC.’s transition to sixth grade would entail a change in locations, planning began as early as January 1996. An IEP meeting was held in May 1996 and continued at a June 7, 1996, meeting that resulted in the completion of an IEP.
K.C. started school on August 26, 1996. Things began badly and KC.’s mother kept K.C. from school for three days and requested a meeting with key school personnel. KC.’s mother complained about the state of the portable classroom and the absence of certain equipment and furnishings. K.C. returned to school on Tuesday, September 3, 1996. Over the next two weeks, KC.’s teachers noted some signs of improvement in her behavior. Her teachers, however, had trouble getting KC. to work at school and her mother aggravated the problem by helping K.C. complete “in-class” assignments at home.
On Friday morning, September 13, 1996, K.C. found a nail outside the portable classroom. She subsequently threatened students and staff with the nail, stuck her teacher in the finger, and hit and kicked several staff members. The incident culminated with KC. calling her mother and reporting that her teachers were trying to murder her.
KC.’s parents kept her from school for the next three days. After a meeting with the principal, she was formally suspended for seven additional days. A new IEP was developed at a meeting held September 26, 1996, and KC. returned to school on September 30, 1996. K.C. was less compliant than before the incident and her mother *980 regularly attended school with her. KC.’s mother was generally disrespectful of KC.’s teachers and their attempts at instruction, effectively taking over KC.’s classroom teaching. KC.’s parents removed her from school on October 7, 1996, and she never returned.
II. Procedural History
On October 9, 1996, both the Board and K.C.’s parents requested a due process hearing relating to the June and September 1996 IEPs. That hearing was held over the course of several days in October and November 1996. The ALJ’s final order found the June and September IEPs were procedurally inadequate, denying K.C. a FAPE. The ALJ ordered the preparation and implementation of a new IEP. The Board then filed the present action in the federal district court for the Middle District of Florida claiming the IEPs in question provided K.C. with a FAPE and seeking a judgment vacating the ALJ’s final order. 1
In August 1997, the district court entered an accelerated scheduling order setting January 15, 1998, and February 1, 1998, as the cut-off dates for discovery and dispositive motions, respectively. No date was set for disclosure of experts. In February 1998, the Board moved to submit additional evidence. Because of the district court’s decision to modify the course of proceedings, 2 the motion was denied without prejudice so the Board could amend it, specifying the need and relevance of any additional evidence it sought to submit. In May 1998, the district court entered an order refusing to extend the discovery deadline without the agreement of the parties. In March 1999, the district court granted the Board’s amended motion to submit additional evidence and denied KC.’s motion to strike Dr. David Rostet-ter’s affidavit. 3 On April 30, 1999, K.C. filed a motion to submit the testimony of an expert to rebut the Board’s expert testimony. The court denied that motion.
Trial was held on June 24 and 25, 1999. The district court vacated the ALJ’s final order and entered a judgment in favor of the Board. This appeal followed.
III. Discussion
A. Evidentiary Rulings
This court has previously set forth the standard of review as follows:
We review a district court’s ruling on the admissibility of evidence for abuse of discretion, and evidentiary rulings will be overturned only if the moving party establishes that the ruling resulted in a “substantial prejudicial effect.” When applying an abuse of discretion standard, “we must affirm unless we at least determine that the district court has made a ‘clear error of judgment,’ or has applied an incorrect legal standard.”
Piamba Cortes v. Am. Airlines, Inc.,
*981 1. Dr. Rostetter’s Affidavit and Testimony
K.C. claims the district court committed reversible error by allowing the Board to supplement the record with the affidavit and expert testimony of Dr. Rostetter. We disagree. The district court is to conduct a de novo review of the ALJ’s findings, and “IDEA specifically provides that the court may take additional evidence and may fashion relief that the court deems appropriate.” Weiss
v. Sch. Bd.,
K.C. argues the Board failed to comply with Fed.R.Civ.P. 26(a)(2)(C) and 26(e). The Board correctly notes the district court never set an expert witness disclosure deadline other than the Rule 26 requirement that expert witnesses must be disclosed at least ninety days prior to trial. See Fed.R.Civ.P. 26(a)(2). Since the Board disclosed its desire and intent to use Dr. Rostetter as an expert witness over a year prior to trial, it cannot be said to have violated Rule 26.
K.C. also argues the district court failed to meet the “Walker standards” for what additional evidence a court may accept in civil actions brought under the IDEA. 4 K.C. contends the Board did not provide a sufficient basis for supplementing the record, failing to demonstrate why Dr. Ros-tetter did not testify at the administrative hearing. K.C. contends Dr. Rostetter’s testimony was cumulative of testimony previously presented at the administrative hearing. These arguments are without merit.
When initially presented with the Board’s motion to supplement the record, the district court denied it and required an amended motion setting forth the evidence the Board wished to present and how it would assist the court. The Board did so, providing a “solid justification” for introducing additional evidence.
Cf. Roland M. v. Concord Sch. Comm.,
2. KC.’s Motion to Supplement the Record
K.C. also claims the district court erred by denying her motion to supple
*982
ment the record. This motion was made on April 30, 1999, more than a year after the close of discovery and the identification of Dr. Rostetter as a supplementary witness for the Board. Although K.C. had “opposed Plaintiffs motion to add an expert, at no time prior to the eve of trial did [she] request that the Court allow [her] leave to designate an expert of [her] own.”
Sch. Bd. v. K.C.,
No. 97-19-CIV-FTM-25D (M.D. Fla. June 21, 1999) (Order denying K.C.’s Motion To Add Expert). “[District courts enjoy broad discretion in deciding how best to manage the cases before them.”
Chudasama v. Mazda Motor Corp.,
B. Free Appropriate Public Education
The Supreme Court has formulated a two-part test in analyzing whether a FAPE was provided in cases arising under the IDEA. The court must determine: (1) whether the state actor has complied with the procedures set forth in the IDEA, and (2) whether the IEP developed pursuant to the IDEA is reasonably calculated to enable the child to receive educational benefit.
Bd. of Educ. v. Rowley,
(1) the program is individualized on the basis of the student’s assessment and performance; (2) the program is administered in the least restrictive environment; (3) the services are provided in a coordinated and collaborative manner by the key “stakeholders”; and (4) positive academic and non-academic benefits are demonstrated.
Cypress-Fairbanks Indep. Sch. Dist. v. Michael F.,
“[W]hether an IEP provided a ‘free appropriate public education’ ... is a mixed question of fact and law subject to de novo review.”
JSK v. Hendry County Sch. Bd.,
In the present case, the district court gave great deference to the ALJ’s extensive factual findings. The district court disagreed, however, with the ALJ’s conclusion that the IEPs (as well as the educational program actually implemented) failed to provide any educational benefit. The district court found the Board clearly developed an individualized program and administered it in the least restrictive environment. It also found the program was implemented in a coordinated, collaborative manner by key stakeholders. The district court found it impossible to address the academic progress component of the final Cypress-Fairbanks factor because of the extremely short period of time K.C. was in school and the difficulty in determining “what effect KC.’s mother’s actions had on KC.’s progress.” Finally, the district court disagreed with the ALJ’s conclusion that KC.’s non-academic progress regressed based on the single incident with the nail. We find persuasive the district court’s application of the facts to the Cypress-Fairbanks factors and its conclusion that “the procedural deficiencies in the June and September 1996 IEPs did not impact K.C.’s right to a FAPE.” Accordingly, we uphold the district court’s decision.
TV. Conclusion
For the reasons set forth herein, we AFFIRM the decision of the district court vacating the final order of the AL J and the judgment in favor of the Board.
Notes
. K.C. also filed a civil action in the district court seeking attorney's fees, costs, damages, and equitable relief based on the ALJ's findings.
. The district court made some decisions about the order in which the consolidated cases comprising this controversy would be resolved, thus restricting the scope of the trial.
.The district court allowed the Board to supplement the record with only one expert and denied the Board's request to add any additional documentary evidence.
. Although
Walker County School District
was decided nearly eight months after the district court's decision in the present case, it endorsed the standard articulated by the First Circuit in
Town of Burlington. See Walker County,
. In any event, the district court did not appear to rely on Dr. Rostetter's testimony. Dr. Rostetter primarily responded to the ALJ’s findings that the June and September 1996 IEPs were proeedurally flawed. Nevertheless, without referring to Dr. Rostetter’s testimony, the district court agreed with the ALJ, finding the IEPs proeedurally inadequate. Thus, any error stemming from the admission of Dr. Rostetter’s testimony, or by denying K.C.'s motion to supplement the record, would not have yielded the "substantial prejudicial effect” necessary to warrant reversal.
Piamba Cortes,
. It is unnecessary for us to decide whether these factors constitute the test in this circuit because they are at least as stringent as any standard this court has articulated.
