Introduction

National Science League

NSL was founded in 1980 by Joseph Quartaro and Henry Hull, two math coaches with more than 30 years of teaching experience. They launched this challenge in conjunction with the U.S. national policy on science education, based on the experience of CML, and with a number of science teachers with extensive teaching experience. This challenge is aligned with the NGSS (Next Generation Science Standard) system, offering a platform for students to challenge themselves. NSL aims to enhance students’ interests in further exploration of science through lively questions. Additionally, students in grades 4–9 who achieve a Bronze Award or higher will be invited to participate in the large-scale and onsite science event—the ASEEDER All Star Science Carnival—held in Shanghai in May 2026.
