When asked about the proportion of "certified" advisors (i.e. passed a test), compared to the total, an Intuit spokesperson answered "about half to two-thirds." These are impressive numbers -- they've managed to separate real dollars from 50,000 accountants & real time from approximately 30,000 of them! Quite an accomplishment. Obviously they've something to offer the profession.
Oh, BTW, this strategy has helped them garner a market share in excess of 94 percent in the face of a blistering Microsoft marketing campaign.
