Is money to attend an organization's annual delegation embly reported as taxable income?

If a national, non-profit, professional organization pays for some of it's members to attend as delegates at the organizations national general embly (caucus), is it required that this money be reported as taxable income on a 1099-MISC? (Yes, the amount would be over $600). -OR- Can it be called a "scholarship" instead and NOT reported to the Fed as taxable income?
