Interventions for Tier 2 and 3 typically involve more intensive levels of instruction, intervention, and support than Tier 1.

The interventions are designed to target specific academic, social–emotional, and behavioral needs. Tier 2 interventions are typically implemented in a small–group setting, meaning that the student receives more specialized instruction than in Tier 1. The instruction may be delivered by a teacher, a paraprofessional, or a specialist, such as a speech–language pathologist.

Tier 2 interventions often focus on improving skills in a specific area, such as reading comprehension or mathematics. Tier 3 interventions are even more intensive than Tier 2 interventions. They are often provided in an individual setting, meaning that the student receives one–on–one instruction. This type of instruction is typically provided by a specialist or a paraprofessional.

Tier 3 interventions may focus on developing complex skills, such as executive functioning or self–regulation, or on helping the student to access the general curriculum. In both Tier 2 and Tier 3, the interventions are typically designed to be short–term (up to several months). They are also often data–driven, meaning that data is collected and analyzed to track progress and ensure that the intervention is effective.

Finally, Tier 2 and Tier 3 interventions often involve collaboration between family members, school staff, and outside professionals. This collaboration helps to ensure that the student receives the most effective and comprehensive intervention possible.
