IEEE-USA has conducted surveys focusing on the compensation of consultants in 2002, 2004, 2006, 2007, and 2009. Other than 2009, these were standalone surveys, and they were not a part of the overall Salary& Fringe Benefits Surveys. In 2009, for the first time, the two survey efforts were combined. As a result, the sampling frame and qualifying definition of consultant were changed from previous implementations. And this year, the results were further filtered to those consultants who also indicated they were employed in their primary area of technical competence (PATC). Not only is the current definition different (consultants are now defined as primarily fee-based and self-employed full or part time and), but the PATC restriction does not apply this year either.
