Learning standards (also called academic standards, content standards and curricula) are elements of declarative, procedural, schematic, and strategic knowledge that, as a body, define the specific content of an educational program. Standards are usually composed of statements that express what a student knows, can do, or is capable of performing at a certain point in their learning progression (often designated by "grade" or its equivalent).
In the United States, textbooks such as Noah Webster's Speller promulgated specific knowledge to be taught to people at specific ages. Chicago superintendent William Harvey Wells expanded this approach by creating a course of instruction for Chicago Public Schools, which he codified in "A Graded Course of Instruction for Public Schools". Thus, the first learning standards originated as a result of content in textbooks, rather than through a systematic, democratic approach. In 1892, the National Education Association convened the Committee of Ten, which codified the first learning standards designed for a national high school audience. One year later, in 1893, the Committee of Fifteen on Elementary Education was formed to determine a standard number of years for elementary education, establish the content and sequence for elementary grades, and explicate a standardized course of training for elementary school teachers. However, the Committee of Fifteen's work focused primarily on defining the timing, content and teacher training for urban schools. As a result, the National Education Agency further formed the Committee of Twelve on the Rural School Problem and, in 1897, released a report intended to bring about the "...widespread consolidation of American rural schools, [to mirror] the conglomerating urban areas of the country...".
