Functional Behavior Assessment in Nevada: What Parents Need to Know

Your child is being suspended repeatedly for behavior that looks a lot like their disability. The district keeps talking about consequences and behavior contracts but has not conducted a systematic assessment of what is actually driving the behavior. Here is what a functional behavior assessment is, when Nevada law requires one, and what happens when the district skips it.

What a Functional Behavior Assessment Is

A Functional Behavior Assessment (FBA) is a formal, structured process for identifying the specific functions — the underlying causes — of a student's challenging behavior. It is not a punishment record or a discipline referral log. It is an assessment designed to answer one question: why is this behavior happening?

An FBA examines:

• Antecedents — what happens immediately before the behavior occurs (specific settings, transitions, academic demands, sensory triggers, adult proximity)
• The behavior itself — defined precisely and observably, not vaguely ("was aggressive" needs to become "struck another student with an open hand during transition from math to reading three times in two weeks")
• Consequences — what happens immediately after the behavior (escape from task, attention from adults, sensory stimulation, access to preferred items)

The hypothesis produced by the FBA identifies the function of the behavior — most commonly escape/avoidance, access to attention, access to tangible items, or sensory regulation. A behavior plan built without knowing the function is essentially random. Giving a student a token board when the behavior is driven by sensory overload will not work.

When Nevada Requires an FBA

Under IDEA and Nevada law, there are two circumstances that trigger a mandatory FBA requirement:

1. Manifestation determination — behavior is a manifestation of the disability. When a student with a disability is subjected to a disciplinary change of placement (suspensions exceeding 10 consecutive school days or a pattern of shorter suspensions that cumulatively exceed 10 days), the IEP team must conduct a Manifestation Determination Review. If the behavior is determined to be a manifestation of the disability — meaning it was caused by the disability or was the result of the district's failure to implement the IEP — the district is immediately required to conduct an FBA and develop or revise a Behavior Intervention Plan. This is non-negotiable.

2. As part of a special education evaluation when behavior is a concern. If a student is being evaluated for special education eligibility and behavior is among the identified areas of concern, a functional behavioral assessment should be included in the comprehensive evaluation. Parents can request this explicitly in writing.

Beyond these mandatory triggers, parents can request an FBA at any time as part of the IEP process. If your child's current Behavior Intervention Plan was developed without a formal FBA — or if the BIP hasn't been updated in years despite continuing behavioral incidents — a written request for an FBA is appropriate.

What a Behavior Intervention Plan Must Contain

A Behavior Intervention Plan (BIP) is the document that results from an FBA. It translates assessment findings into specific, proactive strategies. A legally sufficient BIP includes:

• The target behavior, precisely defined
• The hypothesized function of the behavior, drawn from FBA data
• Antecedent strategies — environmental changes, modifications to routines, or curricular adjustments that prevent the behavior from occurring in the first place
• Replacement behaviors — specific, functionally equivalent behaviors the student will be taught as alternatives (if the function is escape from difficult tasks, the replacement might be requesting a break using a communication card)
• Teaching strategies for the replacement behavior, with responsible staff identified
• Consequence strategies — how staff will respond when the target behavior occurs to avoid inadvertently reinforcing it
• Crisis procedures if safety is a concern
• Data collection methods to track whether the plan is working
• Review schedule

A BIP that consists only of consequences — "student will lose recess, student will be sent to office" — without addressing antecedents or teaching replacement behaviors is not a compliant behavior plan. It is a punishment schedule, and punishment schedules rarely change behavior driven by disability.

Nevada's Restraint and Seclusion Laws

This context matters when behavior escalates. Nevada maintains some of the strictest restraint and seclusion laws in the country under NRS 388.471 through NRS 388.515. Physical restraint, mechanical restraint, and seclusion are prohibited as forms of discipline or behavior management. They may only be used in emergency situations by specifically trained personnel when there is imminent risk of physical injury.

If restraint or seclusion is used, the district must report it to the board of trustees within 24 hours and the board must develop a corrective plan within 30 days. Each school district must publish an annual public report of restraint incidents by school site.

If your child has experienced restraint or seclusion — and you have seen signs of unexplained physical marks, sudden fear of school staff, or distress around school, take that seriously. Request all incident reports immediately in writing under FERPA.

What Happens When the District Skips the FBA

In CCSD and WCSD, where staffing shortages mean Board Certified Behavior Analysts (BCBAs) are stretched across dozens of schools, FBAs are sometimes skipped or conducted superficially. The NDE has found in past complaint investigations that CCSD failed to provide mandated BCBA services to entire cohorts of students — and ordered the district to provide massive blocks of compensatory behavioral services as a remedy.

If your child's BIP was developed without a proper FBA, you have grounds to request a new FBA in writing. If the district refuses, demand a Prior Written Notice under NAC 388.300 explaining the refusal — including what data they used to develop the current BIP and why they believe an FBA is unnecessary. That written justification will be very difficult for the district to defend if the behavior is continuing to occur.

The Nevada IEP & 504 Advocacy Playbook includes guidance on requesting FBAs, evaluating whether a BIP meets Nevada's legal standards, and the written demands that force the district to respond when behavioral supports are inadequate.
