What is PBIS?


Positive Behavioral Interventions & Supports (PBIS) is an evidence-based, multi-tiered framework for improving and integrating all data, systems and practices affecting student outcomes daily.  PBIS is all inclusive, proactive approach to establishing school wide behavioral expectations.  At Dr. Charles R. Drew Elementary School, we apply the Multi-Tiered Systems of Support (MTSS) as a way to align to academic, behavioral, social and emotional supports to improve education for all students.

Goal of PBIS

  • Build effective, positive school environments which increases school safety
  • Improve academic and behavioral outcomes for all students
  • Prevent and/or reduce problem behaviors using a collaborative, assessment-based approach for developing effective instruction and interventions
  • Teach and reinforce appropriate behavior to enhance social- emotional learning leading to meaningful and durable lifestyle outcomes across a multi-tiered system of supports


The PBIS framework uses data in all levels of decision making.  Schools use data to select, monitor and evaluate student outcomes, practices and systems across all 3 tiers.


Strategies used to support students at every level.  In PBIS, interventions and strategies are backed by research in an effort to target the outcomes that schools want to see.


What we as a school achieve through the data, systems and practices that are put in place.  At Drew, our school community sets goals and we work together to see them through.

Layered Approach

3 Tiers of Support (Tiers refer to the levels of support that students receive, not to the students themselves)

Tier 1 Level (Universal Prevention for All Students)

Think of Tier 1 as your foundation because t’s systems, data, and practices impact all students across all settings.  Tier 1 places an emphasis on building prosocial skills and expectations by explicitly teaching and acknowledging appropriate behaviors exhibited by students.

  • Establish a leadership team
  • Consistent scheduled meetings
  • Ongoing data usage for decision making
  • Professional development opportunities
  • Teach school-wide positive behavioral expectations
  • Classroom expectations aligned w/school-wide expectations
  • A continuum for encouraging expected behaviors and discouraging negative behaviors
  • Procedures in place to encourage school-family relationships

Tier 2 (Targeted Prevention for Some)

Tier 2 provides targeted prevention for some students (groups of 10 or less).  Tier 2 supports is for students who are not successful with Tier 1 interventions and supports by themselves.  Here, you are supporting students at risk for developing serious behaviors before they begin to show.  Tier 2 supports are a combination of layering Tier 1 and Tier 2 strategies.

  • screening process to identify students (4 or more behavioral referrals)
  • collection of Fidelity and Outcome data
  • Intervention team
  • Increase in adult supervision
  • Pre-correct behaviors
  • Focused on possible functions of behaviors with access to academic supports

Tier 3(Intensive, Individualized Prevention for a Few)

Tier 3 (Tertiary Level) provides targeted individualized support for some students that may have high risk behaviors.  Tier 3 supports are a combination of layering Tier 1, 2 and 3 strategies.  Here support is tailored to the student’s individual needs using formal assessments.  Some Tier 3 assessments/supports: Functional Behavior Assessment, Behavior Intervention Plan, Wraparound Supports etc.
