Tertiary Interventions (for individual students)

• Assessment-based
• Intense, durable procedures

Secondary Interventions (for some students; at risk)

• High efficiency
• Rapid response

Universal Interventions (for all students)

• All settings
• Preventive, proactive

Positive Behavior Intervention and Supports, or PBIS, represents preventative behavioral instruction delivered to the whole school population in an effort to foster a positive school climate.  Like RTI, PBIS espouses a multi-tier, data-based approach to service delivery. The first tier includes teaching a set of appropriate behaviors within the whole school; the second tier activates behavioral interventions for students who do not respond to the primary instruction, and the third tier involves individualized behavior support plans for students who do not respond to primary or secondary prevention support (McIntosh et al, 2010).
