Tier classification is a system used to categorize items, individuals, or organizations based on specific criteria, such as performance, quality, or risk. This method helps in organizing and prioritizing resources, making it easier to identify which entities require more attention or support. For example, in finance, companies may be classified into different tiers based on their credit ratings. In education, tier classification can refer to the levels of support provided to students. Tier 1 represents universal interventions for all students, while Tier 2 and Tier 3 offer more targeted assistance for those who need additional help. This structured approach ensures that resources are allocated effectively to meet diverse needs.
