Specializing in quality curriculum development for clients at home and abroad, DemiDec was founded in 1994 by two national champion Academic Decathletes with an enduring passion for the program. Since then, we have grown into a leading provider of Decathlon study materials in the United States; over 600 schools nationwide use DemiDec. Looking back, it’s hard to imagine how different Decathlon was in the 1980s and early 1990s.
