Functional Behavior Assessment in Colorado: What Parents Need to Know

Your child has been suspended, sent home repeatedly, or placed in a separate behavioral program, and no one has explained the behavior in any meaningful way. The school keeps describing what your child does — hits, elopes, shuts down — without addressing why. That "why" is the entire point of a Functional Behavior Assessment, and in Colorado, parents have specific rights to request one and demand that its findings drive real intervention.

What a Functional Behavior Assessment Actually Is

A Functional Behavior Assessment (FBA) is a systematic process for identifying the purpose — or "function" — behind a student's challenging behavior. Behavior does not happen in a vacuum. It serves a function: avoiding a task, accessing attention, obtaining something desired, or responding to sensory input. An FBA identifies the antecedents (triggers), the behavior itself, and the consequences that maintain it.

An FBA is not a punishment tool and not a paper exercise. It is a data-collection process that, when done properly, produces a hypothesis about why a behavior is occurring — and that hypothesis directly shapes intervention. An FBA without a follow-up Behavior Intervention Plan (BIP) is incomplete. A BIP without an FBA to justify it is guesswork.

When Colorado Schools Are Required to Conduct an FBA

Under IDEA and Colorado ECEA rules, certain situations trigger a mandatory FBA:

Manifestation Determination Reviews. When a student with a disability is suspended for more than 10 consecutive school days, or when a series of shorter suspensions constitutes a pattern, the district must hold a Manifestation Determination Review (MDR) to determine whether the behavior was a manifestation of the disability. If the MDR concludes it was, the district must conduct an FBA (if one has not already been done) and develop or revise a BIP. See the related post on Colorado manifestation determinations for how this process works.

When behavior impedes learning. Under IDEA, when a student's behavior impedes their own learning or the learning of others, the IEP team must consider positive behavioral interventions and supports. This does not automatically require a formal FBA, but in practice, any significant behavioral pattern affecting educational performance should prompt one.

When requested by a parent. Parents can request an FBA as part of a comprehensive special education evaluation or as a standalone request. The same 60-day evaluation timeline applies: once written consent is obtained, the AU has 60 calendar days to complete the assessment.

How a Proper FBA Is Conducted in Colorado

A legally defensible FBA in Colorado involves multiple data sources across multiple settings and time periods. It is not a teacher filling out a rating scale in 20 minutes. Components typically include:

• Direct observation of the student in multiple environments (classroom, hallway, cafeteria, unstructured time)
• Indirect assessment — interviews with parents, teachers, and the student, plus rating scales
• Records review — discipline records, prior evaluations, CMAS performance, attendance patterns
• Antecedent-Behavior-Consequence (ABC) data collected systematically over time
• Analysis of setting events — factors that don't immediately precede the behavior but make it more likely (hunger, poor sleep, transitions, sensory environment)

The FBA must be conducted by someone with behavioral assessment expertise. School psychologists typically lead FBAs in Colorado, though Behavior Specialists and Board Certified Behavior Analysts (BCBAs) may be involved, particularly for students with autism or significant support needs.

Colorado does not require a BCBA for all FBAs, but parents of students with autism or complex behavioral profiles should ask specifically who will be conducting the assessment and what their qualifications are.

Parent Input in the FBA Process

You are not a passive subject in the FBA process. Your observations matter enormously — you see your child in settings the school never will, and behavioral patterns often look entirely different at home. Insist on being interviewed as part of the assessment, and bring specific examples: when does the behavior occur, when doesn't it occur, what seems to make it better or worse, when did it start, what changed around that time.

Also flag any medical or sensory factors. Unmanaged pain, sleep disorders, sensory processing differences, and medication side effects can all manifest as "behavioral" problems. These factors need to be in the assessment picture.

From FBA to Behavior Intervention Plan

The FBA produces a hypothesis. The Behavior Intervention Plan (BIP) is the response to that hypothesis. A BIP grounded in FBA data should include:

1. Operational definition of the target behavior — specific enough that any staff member can recognize it consistently
2. The identified function — what the behavior is getting for the student
3. Antecedent strategies — changes to the environment or routines that reduce the probability of the behavior occurring
4. Replacement behavior instruction — explicitly teaching a functionally equivalent, appropriate behavior that serves the same purpose
5. Consequence strategies — how staff will respond to the target behavior and reinforce the replacement behavior
6. Crisis procedures if applicable
7. Data collection plan — how progress will be monitored

The most common failure mode in Colorado schools is a BIP that consists only of consequence strategies — "if the student hits, they will be sent to the office" — without addressing antecedents or teaching replacement behaviors. That is not a BIP, it is a punishment menu. It doesn't meet IDEA's requirement for "positive behavioral interventions and supports."

Monitoring and Revising the BIP

A BIP should be treated like an IEP goal: it requires data, progress monitoring, and revision when it isn't working. If the district reports quarterly that the student is still engaging in the same behavior at the same rate, ask what data is being collected and what changes have been made to the BIP based on that data.

If a BIP is not being implemented as written — if staff are not following the antecedent strategies or are defaulting to suspension rather than the plan's procedures — that is an IEP implementation failure. In Colorado, you can file a state complaint with the CDE ESSU for failure to implement an IEP, which includes the BIP when it is incorporated into the IEP.

Behavioral Support in Rural BOCES Settings

One of the most significant gaps in Colorado's behavioral support infrastructure is in rural BOCES districts. Board Certified Behavior Analysts and Behavior Specialists are urban and suburban resources. In a rural district served by a BOCES, behavioral support staff may visit only weekly or biweekly. An FBA conducted by someone who observes the student for one hour a week is going to produce incomplete data.

Parents in BOCES jurisdictions should push for FBA data collected across multiple weeks, conducted by observers in the building on a regular basis — not just periodic visits from a BOCES itinerant specialist. If the BOCES cannot provide adequate behavioral assessment staffing, they must contract with outside providers. The AU's staffing constraints do not suspend the legal requirement for an appropriate evaluation.

For Students With Autism

Colorado tracks students with Autism Spectrum Disorder as a distinct ECEA disability category, and FBAs are standard practice for students with autism who present with challenging behaviors. The research is unambiguous: function-based intervention outperforms punishment-based approaches for students with autism.

For students on the autism spectrum, sensory factors and communication barriers are frequently the underlying drivers of behavioral challenges. An FBA for a nonspeaking or minimally speaking student needs to account for augmentative and alternative communication (AAC) access as a potential function — the behavior may be the only available communication tool. This is a specialized assessment consideration that not every school psychologist has training in. Ask specifically whether the evaluator has experience assessing communication-related behaviors in students with autism.

The Colorado IEP & 504 Blueprint covers BIP requirements in detail, including what to look for in an FBA report, how to challenge an inadequate behavioral assessment, and the ECEA framework for behavioral supports across Colorado's AU system.
