The District Must Consider Outside Data and Private Evaluations

The Legal Requirement: "Shall Consider" Means Must Consider

IDEA does not treat the school district as the sole authority on your child. The statute and its implementing regulations establish, in mandatory language, that the IEP team must consider all relevant information — not just information the district generated.

Three separate provisions create this obligation:

IDEA section 300.324(a)(1) requires the IEP team to consider "the concerns of the parents" and "the results of the initial or most recent evaluation of the child" when developing the IEP. This is not limited to the district's evaluation. Any evaluation — including one you obtained privately — is covered.

IDEA section 300.502(c) is even more explicit: "The results of any [independent educational] evaluation obtained [at public or private expense] ... shall be considered by the public agency ... in any decision made with respect to the provision of FAPE to the child." The word "shall" is not discretionary. It is a legal command. The district must consider the evaluation. Full stop.

California Education Code section 56327 reinforces this at the state level: the IEP team must consider "information provided by the parent" in making eligibility and placement decisions, including "assessments conducted by qualified professionals that are not employees of the school district."

Together, these provisions mean that when you bring a private evaluation, outside medical records, therapist reports, or your own documented observations to the IEP table, the team is legally obligated to consider that information — not as a courtesy, but as a statutory requirement.

What "Genuine Consideration" Requires

The Ninth Circuit's decision in M.M. v. Lafayette School District, 767 F.3d 842 (9th Cir. 2014), is the most important case in this area for California families. The court held that a district's failure to share its own data with parents before the IEP meeting deprived the parents of meaningful participation. The principle extends both ways: just as the district cannot withhold its data from you, it cannot refuse to meaningfully engage with data you bring.

Courts have identified specific behaviors that satisfy — or fail to satisfy — the "consideration" requirement:

What genuine consideration looks like:

1. Pre-meeting review. The team members actually read the outside evaluation before the meeting — not for the first time at the table.
2. Substantive discussion at the meeting. The team discusses the outside evaluation's findings, methodology, and recommendations. Individual team members ask questions, note areas of agreement, and identify specific points of disagreement.
3. Documented reasoning. When the team disagrees with an outside finding, it explains why — citing specific data, test results, or observations that support a different conclusion. "We disagree" is not an explanation.
4. Impact on the IEP. The IEP reflects the team's engagement with the outside data. Either the recommendations are incorporated, the IEP is modified in response, or the Prior Written Notice explains with specificity why the recommendations were not adopted.
5. Prior Written Notice addresses the outside data. The PWN specifically names the outside evaluation, describes its findings, and explains the basis for any disagreement. This is not optional — IDEA section 300.503 requires the PWN to describe the "other options that the IEP Team considered and the reasons why those options were rejected" and "a description of each evaluation procedure, assessment, record, or report the agency used as a basis for the proposed or refused action."

What failure to consider looks like:

1. No pre-meeting review. Team members have not read the evaluation. They flip through it during the meeting or set it aside.
2. Perfunctory acknowledgment. The team says "we received the evaluation" and moves on without discussing its substance.
3. Blanket dismissal. The team rejects the evaluation with a generic objection — "that evaluator doesn't know our students," "that was done outside the school setting," "we rely on our own data" — without engaging with the specific findings.
4. The PWN does not mention the outside evaluation. If the PWN describes the team's reasoning without referencing the outside data you submitted, the team did not consider it in any legally meaningful way.
5. No change to the IEP despite new information. An outside evaluation reveals a previously unidentified processing deficit, but the IEP remains unchanged. The team's failure to explain why the new information does not warrant a change is itself a violation.

The Ninth Circuit Framework: M.M. v. Lafayette

M.M. v. Lafayette School District, 767 F.3d 842 (9th Cir. 2014), is essential reading for California parents. The court held that meaningful parental participation requires access to information. When the district withheld its own assessment data until the IEP meeting, the parents could not meaningfully prepare or respond, and the resulting IEP was procedurally deficient.

The case established several principles directly relevant to outside data:

• Information asymmetry violates IDEA. If one side of the IEP table has all the data and the other side is in the dark, the process is not collaborative.
• Parents have the right to present information, and the team has the obligation to engage with it. The IEP meeting is not a one-way presentation by the district.
• A procedural violation affecting parental participation can constitute a denial of FAPE. Under IDEA section 300.513(a)(2), a procedural violation is actionable when it "impeded the child's right to a free appropriate public education," "significantly impeded the parents' opportunity to participate in the decisionmaking process," or "caused a deprivation of educational benefits."

When Outside Data Conflicts with District Data

Conflicting evaluations are common — and how the team handles the conflict is legally significant. When a private evaluation and a district evaluation reach different conclusions about your child's disability, eligibility, or service needs, the IEP team cannot simply default to its own evaluation. The team must:

1. Examine the methodology. What tests were administered by each evaluator? Were they appropriate for the child's age, language, and disability? Were the testing conditions appropriate?
2. Compare the findings. Where do the evaluations agree? Where do they diverge? Are the differences explained by different test instruments, different testing dates, or different testing conditions?
3. Assess the evaluators' qualifications. Both evaluators' credentials are relevant, but the district cannot dismiss an outside evaluator simply because they are not a district employee.
4. Document the analysis. The PWN must explain how the team reconciled the conflicting data. A PWN that mentions only the district's evaluation — as if the outside evaluation does not exist — fails this standard.
5. Consider requesting additional assessment. If the data is genuinely ambiguous, the team should consider whether additional evaluation is needed to resolve the discrepancy, rather than defaulting to the district's position.

Common District Objections — and How to Respond

"We can't accept that evaluation — the evaluator isn't licensed in California."

The law: Under IDEA section 300.502(e), an IEE must meet the same criteria the district uses for its own assessments, "including the location of the evaluation and the qualifications of the examiner." However, this applies to IEEs at public expense. A private evaluation you paid for is not subject to the district's criteria — it simply must be "considered." Even for IEEs, the question is whether the evaluator meets the qualifications the district applies to its own staff, not whether the evaluator holds a California-specific license. Many evaluators hold national credentials (e.g., licensed psychologist, BCBA) that satisfy district criteria.

Your response: "Please identify the specific qualification criterion that this evaluator does not meet, with reference to the criteria the district applies to its own assessment staff. Under IDEA section 300.502(c), the district is required to consider this evaluation regardless. The evaluator's licensure status does not eliminate the team's obligation to consider the findings."

"That evaluation is outdated."

The law: There is no statutory expiration date for evaluations. IDEA section 300.303(b) requires reevaluation at least every three years, but an evaluation conducted within the past 1-2 years is typically considered current. Even older evaluations may contain relevant diagnostic information — a diagnosis of dyslexia does not expire.

Your response: "Please identify what specific aspects of my child's functioning have changed since this evaluation such that its findings are no longer informative. If the district believes more current data is needed, I request that the district conduct its own updated assessment in the relevant areas — but that does not eliminate the obligation to consider the existing evaluation's findings."

"We have our own evaluation and we're going with our data."

The law: The existence of a district evaluation does not eliminate the obligation to consider outside data. 34 CFR section 300.306(c) requires that in determining eligibility, the team must "draw upon information from a variety of sources." A team that considers only its own evaluation has drawn upon one source — violating the regulation's explicit requirement of variety.

Your response: "Under 34 CFR section 300.306(c), the team is required to draw upon information from a variety of sources. The district's evaluation is one source. My private evaluation is another. The team must consider both and reconcile any differences. If the team disagrees with the private evaluation's findings, I need the Prior Written Notice to explain specifically which findings the team disagrees with and why, with reference to data."

"The private evaluator never observed my child in the school setting."

The law: School observation is one assessment method among many. A comprehensive neuropsychological evaluation that includes standardized cognitive and academic testing, clinical interviews, behavioral observations during testing, and a thorough records review provides valuable diagnostic information regardless of whether the evaluator visited the classroom. The district's own assessments often include components that do not involve school observation (e.g., standardized testing in a testing room).

Your response: "The private evaluator conducted [describe — e.g., 8 hours of standardized testing, a clinical interview, a parent interview, and a comprehensive records review]. The lack of a classroom observation does not invalidate those findings. If the team believes a classroom observation would provide additional relevant information, I welcome that as a supplement — but not as a basis for dismissing the entire evaluation."

"We appreciate the information, but the team has already made its decision."

The law: This statement is a predetermination red flag. Under IDEA, the team's decision is not final until the IEP meeting has concluded and all relevant information — including the outside data you are presenting — has been considered. A team that announces a decision before considering your data has violated both the consideration requirement and the prohibition on predetermination. See Deal v. Hamilton County Board of Education, 392 F.3d 840 (6th Cir. 2004).

Your response: "The IEP team's decision cannot be final until all relevant data has been considered, including the evaluation I am presenting today. IDEA section 300.502(c) requires the team to consider this data in any decision regarding FAPE. A decision made before considering this data is predetermined and procedurally deficient."

"We'll put the evaluation in the file."

The law: Filing a document is not the same as considering it. Consideration requires discussion, analysis, and documented reasoning. Placing a report in a folder and moving on is the textbook definition of failure to consider.

Your response: "I appreciate that the evaluation will be in the file, but IDEA requires more than filing. I am asking the team to discuss the evaluation's findings at this meeting, identify areas of agreement and disagreement, and document in the Prior Written Notice how the evaluation was considered and why any of its recommendations were not adopted."

When Outside Data Changes the Eligibility Picture

The consideration requirement is most consequential when outside data challenges the district's eligibility determination. If the district found your child ineligible for special education, but a private evaluation identifies a disability that adversely affects educational performance, the team must genuinely grapple with that data.

Common scenarios:

• Private neuropsychological evaluation identifies a Specific Learning Disability that the district's assessment missed — often because the district used a discrepancy model that masked the disability in a high-IQ student, or because it administered fewer or different tests
• Independent speech-language evaluation reveals language processing deficits not captured by the district's screening-level assessment
• Private audiological evaluation diagnoses Auditory Processing Disorder that the district did not assess for
• Medical records document ADHD, autism spectrum disorder, or anxiety that has educational implications the district has not addressed
• Private reading assessment using a comprehensive battery (e.g., CTOPP-2, TOWRE-2, WIAT-IV subtests) reveals phonological processing deficits masked by the child's strong vocabulary and comprehension

In each case, the district cannot simply point to its own evaluation as dispositive. If the outside data creates a genuine question about eligibility, the team must resolve that question with reference to all available data — not by choosing the data it prefers.

What To Do Next

The Bigger Picture

Congress built the consideration requirement into IDEA because it understood something that many districts forget: schools do not have a monopoly on information about your child. You know things the school does not know — about what happens at home, about how hard your child works to compensate, about the anxiety that does not show up in the classroom. Outside evaluators know things the school's assessment did not capture — processing deficits that require specific instruments to detect, disability profiles that only emerge through comprehensive testing, nuances that a 45-minute school assessment cannot reveal.

The IEP process was designed to bring all of that information together. Not the district's information. Not only the information that supports the district's position. All of it. When a district dismisses your data, it is not just being rude — it is substituting its own convenience for the collaborative process Congress mandated, and it is making decisions about your child's education based on incomplete information.

You have the right to bring data to the table. You have the right to have it genuinely considered. You have the right to a documented explanation when the team disagrees. And you have the right to hold the district accountable when it treats your contributions as an inconvenience rather than a legal obligation.
