Between 1910 and 1940 the "high school movement" resulted in rapidly increasing founding of public high schools in many cities and towns and later with further expansions in each locality with the establishment of neighborhood, district, or community high schools in the larger cities which may have had one or two schools since the 19th Century. High school enrollment and graduation numbers and rates increased markedly, mainly due to the building of new schools, and a practical curriculum based on gaining skills "for life" rather than "for college". There was a shift towards local decision making by school districts, and a policy of easy and open enrollment. The shift from theoretical to a more practical approach in curriculum also resulted in an increase of skilled blue-collar workers. The open enrollment nature and relatively relaxed standards, such as ease of repeating a grade, also contributed to the boom in secondary schooling. There was an increase in educational attainment, primarily from the grass-roots movement of building and staffing public high schools.
