       Education in our society serves many purposes, but there are three main functions. First, students learn skills that will help prepare them for society. Writing, reading, and mathematics are all essential in today’s workplace and many people learn these skills in school. Second, schools serve communities. Whether by functioning as polling locations during elections or providing safe places for students in temporary living situations, public schools add value to communities. Third, public schools provide a structured environment for children to engage in productive activities during many days of the year while their adult caretakers are working. In other words, public schools also play the role of “daycare” places. These are three of the primary reasons why we have schools in our society.

       In 1821, the first public high school in the United States was started in Boston. By 1900, 31 states required children to attend school from the ages of 8 to 14. As a result, by 1910, 72% of American children attended school. Half the nation’s children attended one-room schools. In 1918, every state required students to complete elementary school. In 1954, the Supreme Court in Brown v. Board of Education unanimously declared that separate facilities were unconstitutional and desegregation began.        These days, students and their caretakers have more choices when it comes to selecting a public school. In addition to the traditional neighborhood schools, charter schools have popped up in major cities across the country. Both charter schools and neighborhood schools fill traditional roles like providing instruction, serving lunch and other meals, and administering the state tests. However, charter schools and neighborhood schools differ in many important ways. One key difference is the amount of time students spend in school. In Chicago, for example, students who attend neighborhood schools do so for about 180 days in a year, each day slightly over six hours long. On the other hand, students who attend charter schools do so for around 200 days in a year, and most charter school days are over eight hours long. While both neighborhood and charter schools provide free public education to students meeting enrollment criteria, students who attend charter schools spend much more time in class.
