If the combination of a schoolwide behavioral support model and group interventions is not associated with improved behavioral outcomes, then more specific and intensive intervention focused at the student level are introduced and monitored in:
◦ a Tier 1 RTI (response to intervention) model.
◦ a Tier 2 RTI (response to intervention) model.
◦ a Tier 3 RTI (response to intervention) model.
◦ all Tiers of an RTI (response to intervention) model.
