Schooling in America has evolved greatly since the early colonial period. Early education began with Puritan families educating their children at home. Later, the Puritans established Latin grammar schools to teach boys Latin, Greek, and the Bible. Over time, laws were passed to establish common schools and make education mandatory throughout the growing nation. The 20th century brought important changes like the establishment of junior high schools, desegregation of schools, and acts protecting students with disabilities and prohibiting sex-based discrimination. Current issues involve school choice, standardized testing, and the separation of church and education.
