“What is the standard setting process that you will conduct in 2017?
After the close of the Q2 2017 testing window, the Board of Examiners will assemble panels that consist of CPAs with experience supervising the work of newly licensed CPAs. There is one panel of CPAs for each section of the Examination. These CPAs will review test questions and performance data for candidates in the Q2 2017 testing window and approve ratings to recommend a passing score for the Board of Examiners approval.
Once the passing score for each section is approved, it will remain in place until there are significant changes to the Examination in the future. Prior to the 2017 standard setting process, passing scores were most recently set in 2004 when the Examination was computerized, and again in 2011 following a revision of the Examination.
After the close of the Q3 and Q4 2017 testing windows, additional data analyses are require for quality assurance and validation purposes.”

As referred in a prior post. I highly doubt that they will release scores earlier due to this process. I do not see it helping them in anyway by changing these dates.
