Two of the objectives of ISCA are to 1) Protect the Public Welfare and 2) Advance the Profession of Soil Classifying.  The Association achieves these objectives by encouraging all soil classifiers to qualify for certification and by providing members with current technical information in soil classification, among other goals of the Association.
