AIFA director Stephen Gay has called into question figures the FSA presented to MPs on how many advisers have reached QCF Level 4.
During a Treasury Select Committee (TSC) session earlier this month, FSA chief executive Hector Sants claimed the FSA's market research showed, in April 2010, around 49% of the advisers had already qualified.
A further 40% were studying and expecting to qualify, Sants told MPs in response to their questions on the level of support for the RDR.
However, Gay has described the figure as "suspect", saying they do not reflect the real situation within the IFA community.
He says: "Their figure comes from a limited sample survey whereas the actual figures are available from professional bodies and if you take them in aggregate and do the sums the figure is a good few percentage points lower than that
"That tells us there is still a significant job of work to do and we need the FSA to heed our continuing calls for flexibility when the deadline comes around."
According to the most recent survey by the PFS of its own members, 42% now hold a diploma which makes them RDR-ready.
Gay also insists the FSA's estimates on the number of advisers to leave the industry because of RDR, currently put at 8-13%, would not be tolerable.
He says: "That sort of number leaving the industry should not something we should consider to be acceptable."
AIFA should redouble its efforts to help as many advisers as possible, he says.
