This is an old post.
As of 2017/18 they have been using the new check sheet, and Part 3 is now carried out using the single assessment sheet (no more PSTs). And DSA is now DVSA, of course.
A while ago the DSA circulated a Quick Guide to the new Standards Check that will replace the Check Test from 7 April 2014.
Within the guide is a link to a PDF file showing what the new Standards Check Marking Sheet will look like from April onwards.
A reader also commented to me recently that the DSA had “taken down” the PST sheets from their website. I wasn’t aware that they had them there, but if they ever did – and it would be great IF they did – I would imagine that these will have to change at some point to keep in line with the Standards Check/CCL approach.
The PST Sheets can be downloaded from the blog here. I stress that I can only vouch for these up until 7 April 2014.
