Topic - K-12 School

K–12 (spoken as "k twelve", "k through twelve", or "k to twelve") comprises the sum of primary and secondary education in the United States, Canada, South Korea, Turkey, Philippines, Egypt, Australia, India and Iran. The expression is a shortening of kindergarten (K) for 4- to 6-year-olds through twelfth grade (12) for 17- to 19-year-olds, the first and last grades of free education in these countries, respectively. The related term P–12 is also occasionally used in Australia and the United States, to refer to the sum of K–12 plus preschool education. - Source: Wikipedia
