The CASS program is recognized for maintaining an extraordinarily high completion and return rate. Currently there are over 4,000 alumni in 17 Central American and Caribbean countries. Since l990, CASS has negotiated 21 credit transfer agreements for CASS alumni with universities in Central America and the Dominican Republic such as the Universidad Nacional de Costa Rica and the Pontificia Universidad Catolica Madre y Maestra in the Dominican Republic. The success of the CASS program is best measured by the ability of CASS scholars to have a positive impact on their immediate environment upon their return to their countries. That is, CASS scholars become individuals who have the capacity and motivation to initiate and support sustainable development through their own actions or by their influence on the actions of others.
Students adopt a region of the country and dedicate a day to cleaning the environment in that area.
The objective is to develop an appreciation of environmental issues among people from all walks of life in the country. In Honduras, a North Coast computer science returnee opened his own computer school, staffed by three CASS returnees. Visiting Ministry of Education officials were so impressed by the curriculum that they adopted it nation-wide. It will serve as the basis for computer studies in the last year of secondary school. In the Dominican Republic, a student of sign language works in the Special Education Office of the Ministry of Education as a resource person in sign language.
