The AHA ranked first of 50 trade associations on six of 15 measures of advocacy effectiveness, the most of any association, according to the results from APCO Worldwide’s annual TradeMarks study. The six areas are member representation, bipartisanship, industry reputation steward, information resource, self-regulation and local impact. The study surveyed 305 policy leaders in Washington – congressional staff, executive branch officials and private sector executives – to identify what makes an association an effective public policy advocate in the eyes of its key stakeholders.
