What is tier 1

Each of these levels represents ways that professionals can intervene in order to diminish problems in their clients. Here we will describe each level without technical jargon, and relate them to our purpose in schools, particularly focusing on student behavior. Most often these three tiers are graphically represented in a triangle diagram. However, these tiers may also be represented as concentric circles.

The tiers may help prioritize the type and intensity of interventions for behavior that students receive. It is possible that any particular intervention can be used at any of these three tiers. What we have done on this website is identify the primary way strategies would be used.

Tier 1. The first level of intervention, called primary or universal prevention, is often called Tier 1 intervention in schools. Tier 1 capital represents the core equity assets of a bank or financial institution.

It is largely composed of disclosed reserves also known as retained earnings and common stock. It can also include noncumulative, nonredeemable preferred stock. CET1 is the highest quality of capital, and can absorb losses immediately as they occur. This category includes common shares, retained earnings, accumulated other comprehensive income , and qualifying minority interest, minus certain regulatory adjustments and deductions.

Additional Tier 1 Capital includes noncumulative, nonredeemable preferred stock and related surplus, and qualifying minority interest. These instruments can also absorb losses, although they do not qualify for CET1. RWAs are all assets held by a bank that are weighted by credit risk. In the Basel accords, the Basel Committee on Banking Supervision set the regulatory standards for Tier 1 and Tier 2 capital that must be reserved by any financial institution.

Tier 2 capital has a lower standard than Tier 1, and is harder to liquidate. It includes hybrid capital instruments, loan-loss and revaluation reserves as well as undisclosed reserves. The difference between Tier 1 and Tier 2 capital reserves relates to the purpose of those reserves. Tier 1 capital is described as "going concern" capital—that is, it is intended to absorb unexpected losses and allow the bank to continue operating as a going concern.

Tier 2 Capital is described as "gone concern" capital. In the event of a bank failure, these assets are used to defray the bank's obligations before depositors, lenders, and taxpayers are affected. While the Basel agreements create a broad standard among international regulators, implementation will vary in each country. The minimum requirements for Tier 1 and Tier 2 capital were set by the Basel Accords , a set of international regulatory agreements set by a committee of central banks and national bodies.

Following the financial crisis, the Basel Committee met again to address the weaknesses that the crisis had exposed in the banking system. The Basel III agreement, published in , raised the capital requirements and introduced more stringent disclosure requirements.

It also introduced the distinction between Tier 1 and Tier 2 capital. Under the new guidelines, the minimum CET1 capital ratio was set at 4. These standards were further amended by the Basel IV standards in , which are scheduled for implementation in January of The effects of the revised standards will vary, depending on each bank's business model.

Tier 1 capital represents the strongest form of capital, consisting of shareholder equity, disclosed reserves, and certain other income.

This allows them to absorb unexpected losses and continue operating as a going concern. CET1 is the main component of Tier 1 capital. It represents the strongest form of capital, which can be quickly liquidated to absorb unexpected losses.

It comprises common stock and stock surplus, retained earnings, qualifying minority interest, and certain other income. The key to PBIS implementation is staff consistency. All staff members need to be aware of goals, process, and measures. Tier 1 implementation may require professional development to orient all school personnel — particularly around at least four core practices:. Before schools start implementing Tier 2 and Tier 3 practices, Tier 1 practices must be in place. These include:.

Rather than establishing specifically what not to do, schools define and teach the behaviors and expectations they want to see.

Schools should identify positively stated, easy to remember expectations. These should align with creating the kind of positive school climate the school wants to create. Anyone should be able to walk into the school at any time and ask 10 random students to name the school-wide expectations.

For students to know the expectations, they must be taught. The Tier 1 team should decide how students will learn expected academic and social behaviors across various school settings.

Students spend the majority of their day within classroom settings. This consistency supports better behavioral outcomes for all students. Teachers explain what the school-wide expectations look like in their classrooms during specific classroom-level routines. No matter the system, it should be:. All discipline policies should include definitions for behaviors interfering with academic and social success. They offer clear policies and procedures for addressing office-managed versus classroom-managed problems.

Defining both the behaviors and the procedures promote consistent application of Tier 1 across all students and school personnel. Teams should solicit stakeholders, including families, for input on Tier 1 foundations.
