Explain the core principles of Positive Behavioral Interventions and Supports (PBIS) and how a school psychologist supports its implementation.

• A. PBIS emphasizes punitive approaches and focuses on individual interventions after problems occur.
• B. PBIS avoids data collection.
• C. PBIS is a proactive, data-driven framework with universal supports and school-wide expectations; the school psychologist supports data analysis, staff training, progress monitoring, fidelity checks, and data-based decision making.
• D. The school psychologist's role is limited to testing.

Answer: (D)

PBIS is a proactive, data-driven framework that uses universal supports and school-wide expectations to promote positive behavior for all students. It focuses on teaching and reinforcing expected behaviors, establishing clear rules, and using a systematic approach to monitor how well the entire school is performing so decisions can be made based on evidence rather than guesswork.

A school psychologist plays a central role in making this work. They help collect and analyze behavioral data to identify trends, assess whether universal practices are effective, and guide decisions about when to adjust supports or layer on targeted or intensive interventions. They participate in functional behavior assessments when individual needs arise, support staff training to implement universal strategies consistently with fidelity, and oversee progress monitoring to ensure ongoing gains. Their collaboration helps ensure that data informs every step of implementation, from setting goals to refining school-wide practices.

Other approaches that rely on punishment or ignore data collection do not align with PBIS. Punitive methods focus on after-the-fact consequences rather than building skills and positive routines, and skipping data collection leaves the team without a reliable basis for decisions. Limiting the psychologist’s role to testing also misses the breadth of expertise and systems-level work needed to sustain a school-wide, data-informed behavior support program.
