The professional standards movement began in 1957 after the Soviet Union launched Sputnik, which caused Americans to question the US educational system and led to numerous reform initiatives. Major reforms included the National Defense Education Act of 1958 which provided funding for STEM education, and the Elementary and Secondary Education Act of 1965 which established standards and accountability and provided funds to close achievement gaps. A Nation at Risk report in 1983 renewed emphasis on core subjects and high standards, calling for reforms like longer school days and years.
