Students who have not demonstrated progress with targeted group interventions at Tier 2 require more time in more intensive interventions. Tier 3 interventions are distinguished from Tier 2 interventions because they are individualized based on data collected in individual problem solving, occur with smaller student-teacher ratios (e.g., ideally 1-on-1, however, groups of 3 to 5 students or a larger group broken into a few groups of 3-5 students, is acceptable for middle and high schools), and possibly occur for a longer duration of time (e.g., more daily minutes or more weeks spent in intervention). About 5-10% of students will require this level of intensive support.
Tier 3 intervention plans include more than what occurs during intervention time. They also include strategies for maximizing student outcomes during core instruction or Tier 1, as well as supports to use at home or in the community. These students should be observed on Branching Minds, where a collaborative intervention plan is developed, monitored, and documented.
