Document 3: Area code 602: North American area code 602 is a state of Arizona telephone area code that covers most of the city of Phoenix. It was one of the original area codes established in October 1947 and originally covered the entire state of Arizona until 1995 when area code 520 was established as the state's second area code. While Arizona's explosive expansion during the second half of the 20th century would have made a split necessary in any event, it was hastened by the demand for telephone lines created by the proliferation of fax machines, cell phones and dial-up Internet connections. Many states introduced new area codes during this time frame for much the same reason. Generally, greater Phoenix retained 602, except for some outer portions of Maricopa County that transferred to 520.
Document 4: List of Arkansas area codes: The state of Arkansas is served by three telephone area codes: 479, 501, and 870. In 1947, when the North American Numbering Plan was first implemented, the entire state of Arkansas was assigned the area code 501. With Arkansas being relatively sparsely populated, this arrangement worked well until 1997, when the phone numbers in area code 501 were in danger of being used up. Area code 870 was created in April 1997 to serve the most rural parts of the state (originally specifically not Little Rock metro, Fort Smith or Northwest Arkansas). In January 2002, area code 479 broke from 501, giving Fort Smith and Northwest Arkansas their own calling code.
Document 5: Education in the British Virgin Islands: Education in the British Virgin Islands is largely free and is a requirement for children ages 5 to 17. The British Virgin Islands has a total of 15 public primary schools and 4 secondary public schools. In addition to the public schools, there are 10 primary private schools and 3 secondary private schools. The School year is from September to June. The British Virgin Islands is a part of the British Overseas Territories and therefore the educational system is very similar to the traditional learning system in the United Kingdom. Primary schools are focused on establishing the basics of an academic curriculum and host students between the ages of 5 to 12. After the completion of Primary school, students move on to Secondary school. Secondary school is for students between the ages of 13 and 17. Following the completion of secondary education, students may write their Caribbean secondary education certificate examination. There are approximately 2,700 students who attend primary school for the first 7 years of their required education, however less than 1,800 students successfully finish the following 5 required years of secondary school and complete their certificate exam. Tertiary Education is by no means required in the British Virgin Islands. Students who chose to continue their education after Secondary Education may move on to an additional 2 years of schooling. After 2 years of Tertiary Education is completed, students may take their Caribbean advanced placement examinations. Passing the exams entitles students the right to continue their studies even further at the University of the Virgin Island. This University is the only tertiary education institution in the British Virgin Islands. At the University, students can obtain associate, bachelors, and master's degrees in the departments of business, education, liberal arts and social sciences, or science and mathematic.
