What is ACSL? 什么是ACSL？
The American Computer Science League (ACSL) is one of the oldest and most prestigious computer science competitions, founded in 1978. It tests students on fundamental CS concepts including number systems, Boolean algebra, data structures, graph theory, and programming. 美国计算机科学联赛（ACSL）是历史最悠久、最负盛名的计算机科学竞赛之一，成立于1978年。 它测试学生的基础CS概念，包括数制、布尔代数、数据结构、图论和编程。
ACSL is approved by the National Association of Secondary School Principals (NASSP) and is an institutional member of the Computer Science Teachers Association. Students compete in teams, with top performers invited to the prestigious Finals competition. ACSL获得全国中学校长协会（NASSP）认证，是计算机科学教师协会的机构成员。 学生以团队形式参赛，表现优异者将被邀请参加享有盛誉的总决赛。
