With Judy and Stew, went through the procedures for the AP test again, to check the instructions, and make sure the new build works OK. Found one problem machine, STN 23, which had its registry settings configured for STN 1; went in as admin and fixed those. All student machines now work except the hors-de-combat STN 1.
Following the testing instructions, though, we found inconsistencies. It's impossible to follow the instructions as they were written, because once you start playing the practice material, the test Start button is disabled and you can't get it enabled again. Basically, you have only one chance to press the test Start button, and that's after you've pressed the Replay button following a hear/record test. Reading the Sanako manual, it appears that the testing system was set up for a test in which the CD plays the whole time, and all that happens is that you pause and un-pause student recording.
So the only practical way we found to administer the test was to go through the Sample / Record / Replay sequence with the Teacher as source, then switch to the CD and queue up the test. Then press Start, and immediately pause the student recording. When you pause the student recording. Then let the intro/practice stuff run its course, and when it's time to record the students, unpause student recording. (When you do that, the CD may pause itself, so you'll possibly need to press Play again). Keep riding the Pause student recording button so that they get to record themselves at the appropriate points. The Stop and Collect.
Judy's documenting this in detail, and we'll post the procedure on the blog when it's done. Scott is going to be running the real test on Monday, but we'll need to be able to do it for the future.
