Functional Behavior Assessment and Behavior Intervention Plans in New Mexico

Your child is being disciplined repeatedly at school. Suspensions are piling up. The IEP team talks about "behavioral issues" but hasn't proposed anything concrete. You're watching your child get pushed out of the classroom — and you're not sure what you can demand.

In New Mexico, two specific procedural tools exist to force a data-driven response to your child's behavior: the Functional Behavior Assessment (FBA) and the Behavior Intervention Plan (BIP). Understanding exactly when the school must conduct these — and when you can proactively request them — is essential advocacy knowledge.

What Is a Functional Behavior Assessment?

An FBA is a systematic process for identifying why a student is engaging in a problematic behavior. Rather than simply responding to the behavior itself, an FBA looks at antecedents (what triggers the behavior), the behavior itself (precisely defined), and consequences (what happens after, which may be maintaining the behavior).

A proper FBA in New Mexico involves direct observation across multiple settings, teacher and parent interviews, review of existing data, and analysis of environmental factors. The goal is to form a hypothesis about the function of the behavior — is the child seeking attention, escaping a difficult task, seeking sensory input, or accessing a preferred item? The answer directly shapes what interventions are likely to work.

What Is a Behavior Intervention Plan?

A BIP is a written plan developed from FBA findings that outlines proactive strategies to prevent the behavior, replacement behaviors to teach the student, and responses that reinforce positive behavior without inadvertently maintaining the problem behavior. A BIP should be individualized — generic "redirect and remove" responses are not adequate BIPs under NMAC.

When a BIP is incorporated into the student's IEP, its provisions are part of the IEP the district must implement. If school staff fail to implement the BIP's strategies consistently, that is an IEP implementation failure — which may support a request for an individualized compensatory-education remedy or a state complaint.

When New Mexico Schools Are Legally Required to Conduct an FBA

Under NMAC 6.31.2.13 and federal IDEA regulations, there are specific triggers for an FBA and BIP:

Manifestation Determination Review (MDR): When a student with a disability receives a disciplinary change of placement — more than 10 consecutive school days, or a pattern of removals totaling more than 10 school days — the district must conduct an MDR. If the MDR team determines that the behavior was a manifestation of the disability, the IEP team must either conduct an FBA and implement a BIP, or review and modify an existing BIP to address the behavior.

Special Circumstances Removal: If a student is placed in an Interim Alternative Educational Setting (IAES) for bringing a weapon to school, possessing illegal drugs, or inflicting serious bodily injury, the placement may last up to 45 school days regardless of whether the behavior was a manifestation. If the MDR finds a manifestation, the team must conduct an FBA and implement a BIP, or review and modify an existing BIP.

Proactive IEP Development: Beyond disciplinary triggers, you can request that an FBA be conducted as part of your child's initial evaluation or any subsequent reevaluation when behavior is identified as a barrier to learning. This is particularly important in New Mexico schools where students with emotional and behavioral disabilities are sometimes suspended and expelled rather than supported, particularly in rural districts with limited access to behavior specialists.

How to Request an FBA

You don't need to wait for a disciplinary crisis. If your child's behavior is interfering with their learning or the learning of others, you can request an FBA in writing at any IEP meeting or as a standalone written request to the special education director.

A simple written request is sufficient: "I am requesting that the district conduct a Functional Behavior Assessment for [child's name] to inform the development of an appropriate Behavior Intervention Plan."

For an FBA requested as part of an initial evaluation or reevaluation, the district must respond with a Prior Written Notice within 15 school days; if it agrees to evaluate, the 60-calendar-day evaluation period runs from informed parental consent, subject to applicable federal exceptions. For a standalone FBA request, ask for a written response and the basis for any refusal.

What a Quality BIP Must Include

A BIP that passes muster under New Mexico's requirements should include:

• A precise operational definition of the target behavior
• The identified function of the behavior based on FBA data
• Antecedent modifications (changing environmental triggers)
• Replacement behavior instruction (what the student should do instead)
• Reinforcement strategies for the replacement behavior
• Consequence strategies that are consistent and not reinforcing the problem behavior
• Implementation responsibilities assigned to specific staff members
• Data collection procedures and a schedule for reviewing progress

If the district hands you a one-page document with generic language like "student will be redirected when behavior occurs," that's not a compliant BIP. You have the right to request a revision.

The New Mexico Rural Context

New Mexico's 32 of 33 counties have federally designated health professional shortages. Board Certified Behavior Analysts (BCBAs) and behavior specialists are concentrated in Albuquerque, Santa Fe, and Las Cruces. In rural and frontier districts, schools may claim they don't have access to qualified behavior analysts to conduct FBAs. Staffing shortages do not eliminate the district's obligation to address the request. Ask the team to identify and discuss delivery options, document the service gap, and consider a state complaint to NMPED's Office of Special Education if the district refuses to act.

Parents Reaching Out (PRO) offers training on understanding behavioral evaluations and IEP rights. Disability Rights New Mexico (DRNM) provides legal support when schools fail to implement BIPs or use disciplinary procedures as a substitute for behavioral support.

The New Mexico IEP & 504 Blueprint includes FBA request letter templates, a guide to reviewing BIP quality, and strategies for documenting service failures in rural districts where itinerant behavior support is inconsistent.
