Education in the United States Grading Scale

In schools in the United States children are continually assessed throughout the school year by their teachers, and report cards are issued to parents at varying intervals. Generally the scores for individual assignments and tests are recorded for each student in a grade book, along with the maximum number of points for each assignment. At any time, the total number of points for a student when divided by the total number of possible points produces a percent grade, which can be translated to a letter grade. Letter grades are often but not always used on report cards at the end of a marking period, although the current grade may be available at other times (particularly when an electronic grade book connected to an online service is in use). Although grading scales usually differ from school to school, the most common grade scale is letter grades—"A" through "F"—derived from a scale of 0–100 or a percentile. In some areas, Texas or Virginia for example, the "D" grade (or that between 70–60) is considered a failing grade. In other jurisdictions, such as Hawaii, a "D" grade is considered passing in certain classes, and failing in others.

Standardized testing
Under the No Child Left Behind Act, all American states must test students in public schools statewide to ensure that they are achieving the desired level of minimum education, such as on the Regents Examinations in New York, or the Florida Comprehensive Assessment Test (FCAT), and the Massachusetts Comprehensive Assessment System (MCAS); students being educated at home or in private schools are not included. The act also requires that students and schools show "adequate yearly progress." This means they must show some improvement each year. When a student fails to make adequate yearly progress, No Child Left Behind mandates that remediation through summer school and/or tutoring be made available to a student in need of extra help.

During high school, students (usually in 11th grade) may take one or more standardized tests depending on their postsecondary education preferences and their local graduation requirements. In theory, these tests evaluate the overall level of knowledge and learning aptitude of the students. The SAT and ACT are the most common standardized tests that students take when applying to college. A student may take the SAT, ACT, or both depending upon the post-secondary institutions the student plans to apply to for admission. Most competitive schools also require two or three SAT Subject Tests, (formerly known as SAT IIs), which are shorter exams that focus strictly on a particular subject matter. However, all these tests serve little to no purpose for students who do not move on to post-secondary education, so they can usually be skipped without affecting one's ability to graduate.

Extracurricular activities
A major characteristic of American schools is the high priority given to sports, clubs and activities by the community, the parents, the schools and the students themselves. Extracurricular activities are educational activities not falling within the scope of the regular curriculum but under the supervision of the school. These activities can extend to large amounts of time outside the normal school day; home-schooled students, however, are not normally allowed to participate. Student participation in sports programs, drill teams, bands, and spirit groups can amount to hours of practices and performances. Most states have organizations that develop rules for competition between groups. These organizations are usually forced to implement time limits on hours practiced as a prerequisite for participation. Many schools also have non-varsity sports teams, however these are usually afforded less resources and attention.

Sports programs and their related games, especially football and/or basketball, are major events for American students and for larger schools can be a major source of funds for school districts. Schools may sell "spirit" shirts to wear to games; school stadiums and gymnasiums are often filled to capacity, even for non-sporting competitions.

High school athletic competitions often generate intense interest in the community. Inner city schools serving poor students are heavily scouted by college and even professional coaches, with national attention given to which colleges outstanding high school students choose to attend. State high school championship tournaments football and basketball attract high levels of public interest.

In addition to sports, numerous non-athletic extracurricular activities are available in American schools, both public and private. Activities include Quizbowl, musical groups, marching bands, student government, school newspapers, science fairs, debate teams, and clubs focused on an academic area (such as the Spanish Club) or cultural interests (such as Key Club).

Education of students with special needs
Commonly known as special classes, are taught by teachers with training in adapting curricula to meet the needs of students with special needs.

According to the National Association of School Nurses, 5% of students in 2009 have a seizure disorder, another 5% have ADHD and 10% have mental or emotional problems.

Educating children with disabilities
The federal law, Individuals with Disabilities Education Act (IDEA) requires states to ensure that all government-run schools provide services to meet the individual needs of students with special needs, as defined by the law.All students with special needs are entitled to a free and appropriate public education (FAPE).

Schools meet with the parents or guardians to develop an Individualized Education Program that determines best placement for the child. Students must be placed in the least restrictive environment (LRE) that is appropriate for the student's needs. Government-run schools that fail to provide an appropriate placement for students with special needs can be taken to due process wherein parents may formally submit their grievances and demand appropriate services for the child. Schools may be eligible for state and federal funding for the (sometimes large) costs of providing the necessary facilities and services.

Criticism
At-risk students (those with educational needs that aren't associated with a disability) are often placed in classes with students with minor emotional and social disabilities. Critics assert that placing at-risk students in the same classes as these disabled students may impede the educational progress of both the at-risk and the disabled students. Some research has refuted this claim, and has suggested this approach increases the academic and behavioral skills of the entire student population.

Public and private schools
In the United States, state and local government have primary responsibility for education. The Federal Department of Education plays a role in standards setting and education finance, and some military primary and secondary schools are run by the Department of Defense.

K-12 students in most areas have a choice between free tax-funded public schools, or privately-funded private schools.

Public school systems are supported by a combination of local, state, and federal government funding. Because a large portion of school revenues come from local property taxes, public schools vary widely in the resources they have available per student. Class size also varies from one district to another. Curriculum decisions in public schools are made largely at the local and state levels; the federal government has limited influence. In most districts, a locally elected school board runs schools. The school board appoints an official called the superintendent of schools to manage the schools in the district. The largest public school system in the United States is in New York City, where more than one million students are taught in 1,200 separate public schools. Because of its immense size – there are more students in the system than residents in eight US states – the New York City public school system is nationally influential in determining standards and materials, such as textbooks.

Admission to individual public schools is usually based on residency. To compensate for differences in school quality based on geography, school systems serving large cities and portions of large cities often have "magnet schools" that provide enrollment to a specified number of non-resident students in addition to serving all resident students. This special enrollment is usually decided by lottery with equal numbers of males and females chosen. Some magnet schools cater to gifted students or to students with special interests, such as the sciences or performing arts.

Private schools in the United States include parochial schools (affiliated with religious denominations), non-profit independent schools, and for-profit private schools. Private schools charge varying rates depending on geographic location, the school's expenses, and the availability of funding from sources, other than tuition. For example, some churches partially subsidize private schools for their members. Some people have argued that when their child attends a private school, they should be able to take the funds that the public school no longer needs and apply that money towards private school tuition in the form of vouchers. This is the basis of the school choice movement.

5,072,451 students attended 33,740 private elementary and secondary schools in 2007. 74.5% of these were Caucasian, non-Hispanic, 9.8% were African American, 9.6% were Hispanic. 5.4% were Asian or Pacific Islander, and .6% were American Indian. Average school size was 150.3 students. There were 456,266 teachers. The number of students per teacher was about 11. 65% of seniors in private schools in 2006-7 went on to attend a 4-year college.

Private schools have various missions: some cater to college-bound students seeking a competitive edge in the college admissions process; others are for gifted students, students with learning disabilities or other special needs, or students with specific religious affiliations. Some cater to families seeking a small school, with a nurturing, supportive environment. Unlike public school systems, private schools have no legal obligation to accept any interested student. Admission to some private schools is often highly selective. Private schools also have the ability to permanently expel persistently unruly students, a disciplinary option not legally available to public school systems. Private schools offer the advantages of smaller classes, under twenty students in a typical elementary classroom, for example; a higher teacher/student ratio across the school day, greater individualized attention and in the more competitive schools, expert college placement services. Unless specifically designed to do so, private schools usually cannot offer the services required by students with serious or multiple learning, emotional, or behavioral issues. Although reputed to pay lower salaries than public school systems, private schools often attract teachers by offering high-quality professional development opportunities, including tuition grants for advanced degrees. According to elite private schools themselves, this investment in faculty development helps maintain the high quality program that they offer.

An August 17, 2000 article by the Chicago Sun-Times refers to the Roman Catholic Archdiocese of Chicago Office of Catholic Schools as the largest private school system in the United States.
