District's Behavior Assessment Flawed for Skipping School Bus Observations; Psych Eval Upheld

What Happened

A 10-year-old boy diagnosed with autism attended school in the Anaheim City School District. His mother described his behavior as increasingly out of control beginning in 2006 — he was kicking and hitting staff, verbally threatening his aide, and, in one alarming incident, threatened to stab the school bus driver while other students with severe disabilities were on the bus. The District responded by requiring Mom to search his backpack daily and banning him from carrying pens or pencils on the bus. After the District conducted a triennial psychoeducational assessment in May 2005 and a functional analysis assessment (FAA) in January 2007, Mom disagreed with both and requested publicly funded independent evaluations. The District refused and filed for due process to defend both assessments.

The case was consolidated from four separate filings — two by the District and two by the student — and by the time of the hearing, the parties had narrowed the dispute to just two questions: Was the 2005 psychoeducational assessment appropriate? And was the 2007 FAA appropriate? The ALJ heard five days of testimony from the District's psychologist, a resource specialist, a program specialist who conducted the FAA, and two expert witnesses hired by the family.

What the ALJ Found

Psychoeducational Assessment (District prevailed):

The ALJ found the District's 2005 psychoeducational assessment met all legal requirements and denied the parent's request for a publicly funded independent psychoeducational evaluation. Key findings supporting the District included:

1. Qualified assessors: The school psychologist (Ms. Denissen) was credentialed and experienced with autism, and the resource specialist (Ms. Castorena) was qualified to administer academic testing.
2. Appropriate test selection: The District used multiple tools to assess cognitive ability, academic achievement, adaptive behavior, and social-emotional functioning — none of which were the sole basis for any determination.
3. Minor errors were harmless: A three-point math error on one subtest score and the use of an older version of one cognitive test did not invalidate the assessment, because neither resulted in lost educational opportunity or harm to the parent's ability to participate in the IEP process.
4. Expert disagreement ≠ invalid assessment: The parent's expert, Dr. Davidson, preferred different tests (e.g., the WISC-IV over the Leiter-R) and wanted more follow-up testing of score discrepancies, but the ALJ held that a district's obligation is to meet legal requirements — not to provide the most comprehensive assessment imaginable.

Functional Analysis Assessment (Student prevailed):

The ALJ found the District's January 2007 FAA was deficient and ordered a publicly funded independent FAA. Key failures included:

1. Failed to observe student on the school bus. The FAA never observed or assessed the student during transportation — despite the fact that he had threatened to stab the bus driver, the District had implemented a backpack-search protocol, and data showed his worst behaviors occurred at the start of the school day (when he arrived from the bus). The bus is part of the educational environment and must be included in FAA observations.
2. Incomplete antecedent and ecological analysis. Because the bus setting was excluded, the FAA could not properly identify what triggered the student's most serious behaviors or what environmental conditions contributed to them.
3. Vague duration reporting. The FAA described behavior duration only as "short duration," which the assessor interpreted internally as three to five seconds, but this was never defined in the report — making it impossible for the IEP team to meaningfully use the data.
4. Incomplete history of prior behavioral interventions. The assessor relied entirely on anecdotal reports from staff and did not collect objective data on what interventions had worked, why, or what had failed. Unsuccessful interventions were not discussed at all.

What Was Ordered

1. The District's 2005 psychoeducational assessment was found appropriate. The parent's request for a publicly funded independent psychoeducational evaluation was denied.
2. The District's 2007 functional analysis assessment was found not appropriate. The student is entitled to an independent FAA at public expense.

Why This Matters for Parents

1. The school bus is part of your child's educational environment. If your child's most serious or dangerous behaviors happen during transportation, those settings must be included in any functional analysis assessment. An FAA that ignores the bus — especially when incidents there have already prompted safety measures — is legally incomplete. Push back in writing if the evaluator tells you they only need to observe classroom settings.

2. Threatening behavior is not automatically an "isolated incident." The District tried to argue that the bus stabbing threat was a one-time event that didn't need to be analyzed. The ALJ rejected this, noting that the District's own response (backpack searches, removing writing tools) showed it was treating the incident as serious. If the District takes safety steps in response to behavior, that behavior likely belongs in the FAA.

3. Vague language in assessments can be challenged. Terms like "short duration" or "extreme/moderate/mild" mean different things to different people. California law requires behavioral descriptions to be in objective, measurable terms. If an FAA uses undefined relative terms, that is a basis to request an independent evaluation.

4. A math error or outdated test version doesn't automatically void an assessment. The ALJ found a three-point calculation error and an older test version to be harmless because they didn't cost the student educational opportunity. Before arguing that a technical flaw invalidates an assessment, be prepared to show how that error actually hurt your child's program or your ability to participate in the IEP.

5. Disagreeing with an assessment interpretation is not the same as the assessment being invalid. The parent's expert wanted more testing and preferred different tools — but the ALJ ruled the District only has to meet the legal floor, not the highest standard of practice. If you want to challenge a district assessment, focus on what legal requirements were not met, not just on what a private expert would have done differently.
