Preventing Interfering Behavior with MTSS

Preventing Interfering Behavior with MTSS

Districts that use MTSS to support students’ social, emotional, and behavioral well-being are typically able to prevent most interfering behaviors and achieve more positive outcomes than those that do not. This requires that districts approach their MTSS work with intention to proactively support the whole child and address student needs. Effective MTSS for the prevention of interfering behavior involves three elements:

  • A Social, Emotional, and Behavioral Health (SEBH) framework 
  • Organization of any additional school systems that support behavioral learning that can be embedded into MTSS tiers
  • Aligning MTSS practices with the Washington Integrated Student Supports Protocol (WISSP), a coordinated set of steps and activities in the MTSS framework to support holistic, culturally responsive, and community-rooted supports for students and families

Social, Emotional, and Behavioral Health (SEBH) Framework

A Social, Emotional, Behavioral Health (SEBH) support framework centers the whole student through an integrated, expanded, and preventative approach to student well-being. Rather than focusing on reacting to student behavior, this framework proactively addresses students’ overall social, emotional, and behavioral health while also responding to interfering behavior and other needs as they arise. SEBH work is also trauma-informed,34  recognizing that trauma can affect any member of a school community, and supporting school and district staff to address traumatic stress by building protective factors that can promote healing and resilience. 

RREI Demonstration Site Finding: SEBH Supports Must Be Desiloed

Demonstration site staff and leaders have shared that SEBH supports, including PBIS, SEL, and school-based behavioral health, must be desiloed. This means they are not viewed as exclusive to any particular staff area of expertise or practice. SEBH supports, including behavior supports, should not be viewed as “special education work” or even “behavior team work” – it should be adopted as part of the collective work of all staff. To be effective, this work must be district-wide, supported by leadership, and involve intentional cultural and mindset shifts.

The SEBH framework embeds support across all MTSS tiers, organizing the school or district’s work in three critical areas:

  • Positive Behavioral Interventions and Supports (PBIS)
  • Instruction for Social and Emotional Learning (SEL)
  • School-Based Behavioral Health

Positive Behavioral Interventions and Supports (PBIS)

PBIS promotes proactive, school-wide tiered strategies for fostering prosocial student behavior, enhancing well-being, and preventing exclusionary discipline practices. When implemented as part of the SEBH framework, PBIS connects students with the level of social, emotional, and behavioral support they need to succeed. PBIS is trauma-informed and can promote the development of several important protective factors for students, including supporting students in developing social connections, adopting a strengths-based approach that facilitates student resilience, and teaching key behaviors related to cognitive, social, and emotional learning.

Behavior support in PBIS is provided across three tiers of intensity and individualization. Decision making typically parallels the process outlined in Section 2: How Do Effective MTSS Teams Make Decisions Based on Data? All tiers must be designed in such a way that allows all students to be included. 

RREI Demonstration Site Finding: Address Patterns of Behavior with Tier 1

When multiple students are engaging in interfering behavior at certain times of day, in certain locations, or during certain activities, teams should address these needs by revisiting Tier 1 supports and determining if they are adequate. Regularly reviewing schoolwide behavior data (e.g., behavior reports, office disciplinary referrals, or other Tier 1 data collected by school staff) can support these decisions through the process described in Section 2.

  • Tier 1 (Universal Supports) includes preventive schoolwide teaching and reinforcement of behavioral expectations, provided equitably to all students. A robust Tier 1, implemented consistently, is an efficient use of school resources. Most students’ needs will be met by Tier 1 practices. However, when Tier 1 is insufficient or inconsistent, more students may have unmet needs and require the resources and support of a higher PBIS tier.
  • Tier 2 (Targeted Supports) typically involves rapid, efficient, and minimally individualized behavior support provided to students who regularly engage in interfering behavior and who don’t respond to consistent implementation of Tier 1 supports. Students supported in Tier 2 must still participate in Tier 1 to the same extent as all other students.
  • Tier 3 (Intensive Supports) are specialized behavior supports designed for an individual student whose needs were not fully met with Tier 2 intervention.35  Typically, this tier includes completing a functional behavioral assessment (FBA) and using the results to develop a behavioral intervention plan (BIP) for the student. For guidance on these processes, refer to Section 4. Each student receiving Tier 3 support must still participate in Tier 1 to the same extent as all other students.

Use of PBIS benefits both students and staff. In schools where PBIS is implemented consistently and correctly, students are excluded from the classroom less frequently,36  achieve better outcomes in terms of academics and behavior,37  and are less likely to engage in substance use.38  Teachers in schools that implement PBIS effectively are significantly more likely to feel effective and prepared to meet their students’ needs, and less likely to report feelings of burnout.39, 40

Instruction for Social Emotional Learning (SEL)

The Collaborative for Academic, Social, and Emotional Learning (CASEL)41  defines SEL as “the process through which all young people and adults acquire and apply the knowledge, skills, and attitudes to develop healthy identities, manage emotions and achieve personal and collective goals, feel and show empathy for others, establish and maintain supportive relationships, and make responsible and caring decisions.”

In January 2020, the SEL Advisory Committee developed and adopted Washington State’s SEL Standards, Benchmarks, and Indicators to provide a framework for identifying and encouraging growth in the following skill areas:

  • Standard 1: Self-Awareness—Individual can identify their emotions, personal assets, areas for growth, and potential external resources and supports.
  • Standard 2: Self-Management—Individual can regulate emotions, thoughts, and behaviors.
  • Standard 3: Self-Efficacy—Individual can motivate themselves, persevere, and see themselves as capable
  • Standard 4: Social Awareness—Individual can take the perspective of and empathize with others from diverse backgrounds and cultures.
  • Standard 5: Social Management—Individual can make safe and constructive choices about personal behavior and social interactions.
  • Standard 6: Social Engagement—Individual can consider others and show a desire to contribute to the well-being of school and community.

Evidence strongly suggests that widespread integration of SEL strategies promotes healthier peer relationships, improved student well-being, and safer learning environments42 . When SEL is embedded across content areas, it provides students an opportunity to continuously learn about, practice, and grow in essential violence-prevention skills such as self-regulation and productive problem solving.

School-Based Behavioral Health 

Behavioral health encompasses mental health as well as psychological, social, and emotional wellbeing.43  School-based behavioral health includes interventions that students receive to enhance social, emotional, and/or behavioral well-being. These services range from school-wide prevention efforts, curriculum and trainings, to individualized services. They include those provided on site, in a school-based health center, and/or in partnership with community based organizations. For children and youth, mental and behavioral health are directly related to to academic outcomes and physical health. 

School-based behavioral health involves early identification of mental health issues, access to counseling and psychological services, and fostering a school environment that supports mental health awareness. Student behavioral health is a growing and underserved area of need, and difficulties in this area can lead to interfering behavior.44  Services can be efficiently incorporated into MTSS tiers as part of the SEBH framework. The Interconnected Systems Framework (ISF) can support schools and districts in this area to provide tiered supports: 

  • Tier 1: Universal prevention, incorporating universal behavioral health screenings and support for school/home partnerships, trauma-informed training for school staff, other prevention activities, and integration with PBIS and SEL as part of overall SEBH support
  • Tier 2: Targeted interventions, such as one-to-one or small-group interventions
  • Tier 3: Supports for students in need of wraparound services

Additionally, school staff well-being is linked to student behavioral health and well-being. Districts and schools prioritizing SEBH should also take steps to ensure the well-being of their staff is actively considered and supported. For more, refer to “Supporting Educator Wellbeing” below.

For further information and resources on school-based behavioral health, see the following:

Additional School and District Systems that Support Behavioral Learning

Schools and districts that use some or all of the SEBH framework in their MTSS work may also have additional systems that can be leveraged to support positive behavioral growth. The school and district systems below can be organized within MTSS work, support student SEBH well-being and prevention of interfering behavior, and can lead to a healthier school climate for students, families, and staff.

Culturally Responsive and Sustaining Practices

Culturally responsive and sustaining practices promote student equity by ensuring the school environment affirms, rather than disconnects, students of all races, ethnicities, languages, and cultures. It is asset based and aims to weave in the cultural practices, identities, and linguistic backgrounds of each student in a given classroom, building, school, or district. Culturally sustaining practices embrace and reflect the lived experiences of each student, and are a critical element of high-quality instruction in a safe and inclusive classroom environment. They also create a more welcoming environment for parents and other family members to participate as members of the school community. 

Culturally responsive and sustaining practices are directly related to equitable and student-centered behavior support. These practices allow classrooms and schools to authentically reflect students’ identities, strengths, and needs, which can result in less interfering behavior as students feel more connected, seen, and supported. In addition, these practices lead to more engaging core instruction as there are multiple entry points for students to engage in learning that taps into their lived experience. School and district staff must also be supported in their awareness and understanding of their own cultural and linguistic heritage, and how those experiences may unconsciously create expectations related to behavioral norms and values. 

For examples and nonexamples of culturally responsive and sustaining practices related to positive behavior support, refer to the PBIS Cultural Responsiveness Field Guide from the Center on PBIS.

Engaging and Effective Instruction

Washington State identified eight criteria areas for professional performance capabilities and development of certificated classroom teachers. Each of these areas provides guidance for how teachers can take a holistic approach for delivering engaging and effective instruction:

  1. Expectations: Centering instruction on high expectations for student achievement
  2. Instruction: Demonstrating effective teaching practices
  3. Differentiation: Recognizing individual student learning needs and developing strategies to address those needs
  4. Content Knowledge: Providing clear and intentional focus on subject matter content and curriculum
  5. Learning Environment: Fostering and managing a safe, positive learning environment.
  6. Assessment: Using multiple student data elements to modify instruction and improve student learning
  7. Families and Community: Communicating and collaborating with families and school community
  8. Professional Practice: Exhibiting collaborative and collegial practices focused on improving instructional practice and student learning

Engaging and effective instruction is commonly considered the foundation for effective classroom management.45  Recommended practices include providing accessible ways for students to learn and show their understanding, teaching important concepts in multiple ways, ensuring instructional pacing and opportunities to respond are well-timed for students, using a variety of student groupings and response strategies, and guiding instructional practices and supports with formative assessment. Practices should be grounded in strengths-based and culturally sustaining pedagogy, provide flexibility to anticipate and respond to student needs, and ensure multilingual learners and students with disabilities can access rigorous and grade-level content. For specific instructional and classroom management practices, see Section 3 of this manual.

Family Engagement

Family engagement is defined in the Family Engagement Framework as “a full and equitable partnership among families, educators, providers, and communities to support learners’ development from birth through college and career. It is a collective responsibility that means doing with—not doing for—families.”  In this framework, principles of effective family engagement include:

  • Recognizing the inherent strengths and belonging of each and every family and student
  • Valuing families as experts in their children’s education
  • Affirming the diversity of family types, including using a multi-generational lens and building cultural and linguistic competency
  • Establishing strong and trusting relationships and two-way communication between families and school staff
  • Sharing power and responsibility with families to co-design instruction and student support

Family engagement improves individual student outcomes in behavior, academics, school attendance, and participation in healthy activities.46  For students with social, emotional, and/or behavioral needs, family engagement can enhance students’ sense of belonging at school and can ensure productive and trusting collaboration so each student receives the support they need.

Inclusionary Practices and Outcomes 

Decades of research show that inclusion of students with disabilities (including those with extensive support needs) confers many academic, social, emotional, and behavioral benefits to all students, with and without disabilities.47 ,48  Inclusive education for students who receive special education services involves both access and learning in general education and the inclusive Individualized Education Program (IEP). All members of a student’s educational team, including the student and family, have a role to play in effective instruction and support in inclusive settings. 

Inclusionary practices require a team vision and expectation that each student can actively participate, belong, contribute, and learn in the school and larger community. This involves meaningful collaboration between special education teachers, general education teachers (including multilingual teachers), related service providers, families, and students. The result is a diverse, vibrant, and caring learning environment that embraces and celebrates the contributions of each to the whole. This benefits all students, including those without disabilities.

As school teams work to ensure that special education services in their schools and districts are inclusive, they should reflect on the following guiding questions:

  1. Does each student with an IEP experience belonging as a member in their school and general education classroom(s)? 
  2. Does each student with an IEP actively participate at school across the school day?
  3. Is each student with an IEP learning the grade-level general education curriculum?

It is important for all students, including students with disabilities, to experience supportive and positive relationships with general education staff and feel belonging in their general education classroom communities. For the student with a disability who engages in interfering behaviors, that network of relationships can ensure the student feels safe and supported enough to try new behaviors, ask for help, and engage in learning.

Student interfering behaviors can occur as a result of unaddressed barriers the student experiences in their learning environment, instruction, access to communication, social opportunities, or other school activities. Students eligible for special education services should also be included in school and district MTSS and SEBH support work, which means they must have access to the Tier 1 supports that all students receive, and should also receive Tier 2 and/or Tier 3 supports if determined necessary by the MTSS team. For a student eligible for special education services who engages in interfering behavior, school teams should always consider whether the IEP is adequate and a good fit to ensure the student’s behavioral needs and other support needs are met. For more, refer to Section 5.

Restorative Practices

Restorative practices are commonly defined as a continuum of proactive and responsive strategies embedded within policies and processes that focus on preventing conflict through building and maintaining relationships and resolving conflict through repairing harm and restoring the impacted community. Deeply rooted in indigenous cultural practices, these approaches focus on developing respect, empathy, and accountability with the intention to change behavior, repair harm, and cultivate a culture of belonging.49  

Preventative measures include ongoing culturally- and trauma-informed staff trainings on understanding underlying causes of student behavior, consistent integration of classroom-based procedures and routines that build community and establish a safe and supportive learning environment, and embedded opportunities for students to develop and practice SEL and problem-solving skills. Universal implementation of these preventative measures is essential for the success of conflict resolution strategies. Without these foundational relationships, practices, and shared-understandings, restorative circles, conversations, and conferences are less likely to be effective and can sometimes cause additional harm to relationships and communities. 

Research shows that a reliance on punitive disciplinary practices not only increases misbehavior but is disproportionately used to punish students with disabilities and students of color. By implementing classroom and building-wide restorative practices focused on a culture of community, proactively working to meet student needs, and training both students and staff in conflict resolution skills, schools have reported a decrease in referrals and disproportionate discipline data, and an improvement in overall student behavior and school climate.50

Universal Design for Learning (UDL) 

Recognizing the diversity of learners within each classroom, the research-based51  UDL framework provides a guide for how educators can design flexible learning environments and curricula within any content area to ensure all students can equitably and inclusively engage in challenging and meaningful learning. Neurodivergence52  and other differences in student learning should not be viewed as deficits or exceptions to the “norm,” but rather as natural and expected human variations from one individual to another. School staff who use a UDL lens to embrace instead of stigmatize learner variability can engage in more productive and student-centered support, including positive behavior support when needed. 

The UDL Guidelines53  provide suggestions for how educators can intentionally consider student access, support, and executive functioning by designing multiple means of:

  • Engagement – with options for welcoming interests & identities, sustaining effort & persistence, and emotional capacity;
  • Representation – with options for supporting perception, language & symbols, and building knowledge; and
  • Action & Expression – with options for interaction, expression & communication, and strategy development.

UDL emphasizes that, by setting up the learning environment to anticipate learning style variabilities and proactively providing accommodations for identified needs and abilities, educators can more effectively remove common barriers for how their students access, process, and engage in learning. These practices align with and provide a helpful foundation for implementing other systems within this section such as inclusionary practices, SEL, and restorative practices. Preventative strategies that recognize and mitigate common instructional and learning-based stressors or activators enable more students to stay engaged, feel valued, and achieve UDL’s goal of developing learner agency.

Providing all students with multiple ways of communicating learning, emotions, preferences, needs, and distress is an important part of UDL. Since student interfering behavior is often a way to communicate a need, embedding universal communication supports54  across school environments and activities is often effective at preventing interfering behavior. In addition, when adults provide all students with multiple ways to communicate and understand each other, they are more likely to be safe in the event of a crisis, medical emergency, or other unforeseen event.

Finally, increased educator awareness of neurodiversity can support building teams in universally designing school and classroom environments to be comfortable and accessible for all students. This can result in students having more pathways to access the tools and resources they need to learn and advocate for themselves when they need extra help, resulting in less interfering behavior in classrooms. Examples include:

  • School and classroom expectations are designed intentionally to be anti-ableist 
  • Spaces are organized without unnecessary clutter and distractions 
  • Inviting and comfortable break spaces are provided in common areas and learning spaces
  • Flexible seating and standing options are available in classrooms
  • Students have regular opportunities for movement, attention breaks, and quiet time
  • Healthy self-regulation behaviors (e.g., stimming, doodling, using fidget toys) are normalized and understood by school staff to enhance learning, attention, and/or comfort for some students
  • Students are supported to learn organization skills using tools (e.g., checklists, homework folder, graphic organizer) modeled and taught by staff
  • Students are able to exercise and express choices and preferences about how they learn and show what they know
  • A variety of strategies to communicate requests, needs, and feelings are taught and made available to all students

Aligning MTSS Practices with the Washington Integrated Students Supports Protocol (WISSP)

To support efforts in reducing restraint and eliminating isolation, schools can align their MTSS practices with the Washington Integrated Student Supports Protocol (WISSP) as established under RCW 28A.300.139. The WISSP provides an overarching approach that expands the MTSS efforts to include school and community needs and assets when planning, delivering and evaluating student services. This protocol provides a comprehensive, school-based approach that utilizes an MTSS framework to promote the success of all students by addressing both academic and nonacademic barriers to learning. By incorporating essential components such as needs assessments, resource mapping, community partnerships, integrated support coordination, and continuous data monitoring, schools can proactively identify and respond to student needs before behaviors escalate. Using the WISSP allows educators and administrators to create a supportive environment that prioritizes early intervention, reduces reliance on reactive measures like restraint and isolation, and fosters a safe, inclusive school climate for all students.

For further guidance on using the WISSP together with an MTSS framework to support the social, emotional, and behavioral health of all students, visit OSPI’s Learning Assistance Program (LAP) webpage and download the following resource documents from the sidebar:
