Section 1 (NYSPHSAA)

Section 1 is a high school athletic organization that is one of the eleven sections of the New York State Public High School Athletic Association (NYSPHSAA). It is made up of high schools from around the southern portion of the Hudson Valley. The section offers "modified athletics" administration covering grades 7-9 middle school competition in area middle schools (grade 9 is officially part of the high school level). Schools will sometimes compete with other schools outside of the section in tournaments or invitationals. The section is further divided into leagues based on mostly location but also the size of the school. The schools in the section compete with each other over the course of three seasons, fall, winter, and spring.
