• Structure: 高卒 is read こうそつ and abbreviates 高校卒業, meaning high school graduation or that educational qualification.
• Basic usage: It is used for education requirements in job listings or the career of someone who entered work after high school.

  • In 高卒以上, 以上 includes the high-school-graduate threshold itself. The phrase means high school graduation or higher, rather than requiring education strictly above that level.
