Delaware

History
Delaware has been sending teams to the National Science Olympiad since back in 1985. Its teams generally fare well at nationals. Since 2000, Henry B. du Pont Middle School has utterly destroyed all competition in the B Division, while The Charter School of Wilmington controls Division C. The Charter School of Wilmington particularly does well, placing consistently in the top 20 at nationals.
