K-12 knowledge refers to the primary and secondary knowledge that a student acquires during his schooling. K-12 knowledge is a shortened phrase used for knowledge from pre-school to 12th. The phrase K-12 knowledge is relatively new to India and is generally more commonly used in western nations like United States of America, Canada etc and in areas of Australia. With technology transcending boundaries, the phrase K-12 knowledge is fast becoming more popular in other areas of the world as well, with minor/ no modifications. In some nations the phrase has been replaced with PK-12 or P-12 that means prekindergarten to 12th or toddler to 12th. Whatever nomenclature any country switches into, the concept of K-12 knowledge primarily moves around the training and learning imparted in the school.
