what percentage of the us has a high school diploma
Educational attainment in the United States Since 1983 the percentage of people either graduating from high school or failing to complete high school but getting a GED certification has increased from 85% to 88%. The greatest increases in educational attainment were documented in the 1950s, 60s and 70s. In the 1950s and much of the 1960s high school graduates constituted about 50% of those considered adults (25 and above). For young adults aged between 25 and 29, the percentage of either high school graduates or GED obtainers was roughly 50% in 1950 versus 90% today.[2]
Middle school Middle schools in the United States usually cover grades 5-8, 6-8,7-8, or 7-9. Historically, local public control (and private alternatives) have allowed for some variation in the organization of schools. Elementary school includes kindergarten through to sixth grade, or kindergarten through to fifth grade, i.e. up to age 12, but some elementary schools have 4 or 8 grades, i.e. up to ages 10 or 14[28] (also known as, the intermediate grades). Basic subjects are taught and students often remain in one or two classrooms throughout the school day, except for physical education, library, music, and art classes. In 2001, there were about 3.6 million children in each grade in the United States.[29] "Middle schools" and "junior high schools" are schools that span grades 6 to 8 and 7 to 8, respectively,[28] but junior high schools spanning grades 7 to 8 were common until the 1980s.
