Final answer:
Second-tier intervention targets 10 to 15 percent of students who are at-risk for academic or behavioral challenges but do not exhibit severe problem behaviors, and is part of the multi-tiered support systems in education.
Step-by-step explanation:
The goal of second-tier intervention within an educational framework is to provide additional support for students who are at-risk of academic or behavioral issues but are not currently manifesting severe problem behavior.
This type of intervention is typically designed to support around 10 to 15 percent of the student population.
Second-tier interventions are part of a multi-tiered system of support (MTSS) or Response to Intervention (RTI) model, which includes three tiers of interventions that range from universal interventions for all students (first tier) to intensive interventions for a few students with significant needs (third tier).
