A. GENERAL STRUCTURE
1. Team Divisions
a. There will be two divisions: David Ricardo and Adam Smith.
b. The David Ricardo division includes teams of students enrolled in one-semester (or less) general economics courses or courses which include introductory economic concepts (social studies, business, personal finance, etc.). The course must be taught by a secondary teacher.
c. The Adam Smith division includes teams of students enrolled in Advanced Placement (AP Micro, AP Macro, or AP Micro and Macro), International Baccalaureate (pre-IB and IB), honors, two-semester, or any other advanced courses in economics (including courses taught by a secondary teacher where students earn college credit). The course must be taught by a secondary teacher.
d. Any team consisting of one or more students enrolled in a course listed in A.1.c. must play in the Adam Smith division.
e. Teams shall only compete against other teams in their own division.
2. Team Composition
a. Teams shall be comprised of no more than four (4) members.
b. Competing with only three (3) members, if necessary, is possible and permissible.
c. All members of a team must be from the same public, private, or home-based high school.
d. A school which qualifies for the national semi-final and/or national final competition may reconstitute the members of its team prior to the competition. Students must, however, meet the general student eligibility conditions in A.3., as well as, the eligibility conditions for the division in which the school qualified (see A.1.).
3. Student Eligibility
a. Students must be enrolled for credit in a qualifying high school course (see A.1.b and A.1.c.) at some time during the 2011-2012 academic year.
b. Students who have taken or are taking economics courses for college credit from a post-secondary instructor are not eligible to compete.
c. Students who have taken more than one semester of economics at any time must compete in the Adam Smith division. In particular, students who are in their second semester of any economics course must compete in the Adam Smith division.
d. No student is permitted to compete in the David Ricardo division more than one year. Any returning student who has already participated in the National Economics Challenge (at the state-level or higher) must compete in the Adam Smith division in subsequent years, regardless of previous or current coursework.
e. Home-schooled students must compete in the Adam Smith division.
f. Students who are not enrolled in courses described in Section 1.a-b during the 2011-2012 year, may participate on a team if coached by a school-sanctioned teacher if they do not violate eligibility requirements of Section 3.b.
