A State Corporation Commission was created for the first time in the Commonwealth to control corporations such as the public transportation companies and the telephone and telegraph companies. Other governmental changes provided for in this constitution were: the direct election of the Secretary of the Commonwealth, the State Treasurer, the Commissioner of Agriculture and Immigration and the Superintendent of Public Instruction by the qualified voters; the replacement of County Courts by Circuit Courts; the constitutional requirement for the political status of a city: an incorporated community with a minimum population of 5,000 inhabitants is eligible to become an independent city, and, as the name implies, such cities are not subject to county administration; the establishment of racial segregation in the public schools of Virginia; a considerable extension of the powers of the State Board of Education, and a change in the age range used to determine school population as a basis for distributing the common school fund from 5-21 years to 7-20 years. On May 29, 1902, the Constitution of 1902 was "proclaimed" by the convention members, whose delegates voted for its adoption. Although this Constitution was never ratified by the voters themselves, it was later approved by the state legislature. With certain revisions which were added later, this Constitution of 1902 is the present Constitution of the Commonwealth. In spite of the political influence which had been prevalent in the public school system of Virginia in the 1880's, by the early 1900's numerous educational improvements had resulted: the local general public began to favor a public school system; professional teacher training methods were developed; a Virginia State Education Association was formed; simultaneous examinations for teacher certification throughout the state were standardized; state summer normal schools were organized; teacher scholarships were created, and education conferences were held.
