General information
As in 2005, the ACM Regional South American Contest is split into two, called "The S.A Contest within Brazil" and "The S.A. Contest outside Brazil", this year with 7 sites altogether: Argentina, Bolivia, Brazil, Chile, Colombia, Peru and Venezuela. Please check the home pages for local information. However, this year, both Colombia and Venezuela will have tiered contests.
 

Regional rules
Tiered subcontests in South America (Brazil, Colombia and Venezuela) have special rules for qualifying teams to their respective main sites of the South American Contest. All other rules regarding eligibility, appeals, and advancement to the 2007 finals apply to all sites.
Except for the topics explicitly covered in this page, the rules for the South American Contest conform to the rules published at the ACM International Collegiate Programming Contest site, more specifically at this link. For quick reference regarding eligibility rules, click to view the eligibility decision tree.
For the purpose of finals slot allocation, South America was divided into 3 regions: South America-South (Argentina, Bolivia, Chile and Peru), South America-North (Colombia and Venezuela) and Brazil. Each of these regions has, guaranteed, one slot to the 2007 finals, which will be assigned to the best team in that region. Additional slots that may eventually be assigned to South America will be distributed to the 3 regions according to the following rule, which is based in the number of schools registered in the 2005 South American Contest.
Each additional slot "costs" 21 registered schools. The initial "credit" of each region is the number of fully registered schools in 2005. Then, additional slots are assigned to regions in order of highest current credit.   In case of ties, the region with less currently assigned slots gets the slot. In case of a further tie, the team with best overall score in South America, and that still has not advanced, will be assigned this slot. 

(Of course, this rule assumes that at least 3 slots will be assigned to South America. Given the participation level of previous years and the current numbers in the registration system, we anticipate that 3 slots are a reasonable expectation.)

According to 2005 participation numbers,  the South region had 37 schools competing, the North region had 51 schools and Brazil had 81 schools. Supposing that 6 slots will be assigned to South America, we will have:
               initial     after      after     after     after
                 count   3 slots    4 slots   5 slots   6 slots

South             37:0      16:1       16:1      16:1      16:1
North             51:0      30:1       30:1      30:1       9:2
Brazil            81:0      60:1       39:2      18:3      18:3
where (x:y) means (current credit:slots assigned). Thus, Brazil will end up with 3 slots, the North Region will end up with 2 slots and the South Region will get 1.
Registration

Registration for all sites are open at the ACM International Collegiate Programming Contest Site, except for the tiered sites, whose specific rules determine the advancement of teams to the final round.
