The educational system mirrors the food/nutrition pyramid. This pyramid of education contains 5 tiers with the top tier containing the educational theory and the theorists that define what it is to learn and educate. The second tier of the pyramid contains the federal laws and policies that decide how education is to be defined and practiced in a uniform manner across society. These laws and policies are often based off of the educational theories, but at times they are developed in response to domestic and international trends. This could mean putting a strong focus on math and science education as the U.S. did during the Cold War. While these policies and laws exist in principle, it is the next tier of the pyramid – the state and local government – that refines these policies to reflect the needs and opinions of a more specific community. It is not until the fourth tier down that implementation can begin to take place. In this fourth tier is the school structure that consists of principals, guidance counselors, and the administration. In these tiers, specific goals, rules, and regulations are concocted and put in place for a very specific population of students. It is not until the fifth and final tier that the classroom appears. In theory, the classroom consists on two groups of individuals: teachers and students.
