At the turn of the century, schools in the south and many in the north were segregated. The 1896 Supreme Court ruling, Plessy v. Ferguson upheld the legality of segregation.
By 1900, 31 states had compulsory school attendance for students from ages 8-14.
By 1918, every state required students to complete elementary school.
From the 1920s, more education subjects were introduced. Schools focused on maths, English and social studies.
Finally, in 1954, the Supreme Court overturned its ruling with the landmark case, Brown v. Board of Education, and public schools became open to people of all races.
In the 1950s, public school attendance rose to 75%.
