My daughter says they ask the kids to skip to a particular page in the book and then start taking the test.

I obviously don't know the testing procedure and where exactly things can go wrong, but you'd hope they have some checks to make sure all the kids with a particular proctor, or a particular test day, etc. scored strangely low..

Maybe there was some procedural error where they were told to turn to the wrong page, or the stack of tests was graded according to the wrong key code?

If you take the results and then "group" the scores in various ways (by day, by proctor, by specific test class, etc.) and then look at the ranges -- min/max/avg/median -- this should show if there were any procedural errors. I'm a data person, I think this would be a fun exercise. :-)

Hopefully they do this, but I understand with the budget cuts, etc. maybe they don't have the quality control, but even if they did find a mistake what can they do about it at this point?

Probably the easiest check would be to see if there was at least 1 other person in the same classroom as my daughter, taking the same test, following the same instructions, who scored in the 90's.
