ust posted a comparison table of pass rates for the different boards on the new Folens blog here (which by the way also looks pretty good; I’ve subscribed)
The key comment from her psychexchange forum post is:
The fact that the different boards probably do attract slightly different cohorts mean that direct comparisons are not possible but there are certainly some major differences in pass rates.

GCSE exams coming soon and GCE summer exam are here.
For psychology, candidates currently working towards their AS exams in May, and A2 exams in July there will still be a number of opportunities for re-sits.
AS re-sits will be available in January 2009 and then the following May 2009. No more re-sits of the current AS psychology exams will be available after May 2009.
A2 re-sits will be available in January 2009, June 2009, January 2010 and June 2010.
Of course, only those units that are normally offered in January will be available in January.
For those psychology candidates studying the new specifications, the A2 units will not be available for examination until 2010, which means that candidates cannot complete the full A level in the first year of the new specifications.
Furthermore, the units from the current (legacy) specifications cannot be combined with units from the new specifications.

The draft 2009 psychology GCSE specifications from OCR and AQA have been published.
The drafts have to be submitted to the regulators in April 2008 and the specifications will be available from September 2008, with first teaching from September 2009.
Edexcel and WJEC have announced that they will offer GCSE psychology from 2009 but have not yet published their drafts.
The OCR GCSE draft psychology specifications are here
The AQA GCSE draft psychology specifications are here
Update – here is the link to Edexcel draft GCSE specifications
