Jennifer,

At the very least, of course, you can cut the form number off the bottom.  But you may be worried about students doing "pattern recognition" so here's how some folks deal with that:

They do not use the whole IF-AT form on a given test (i.e., they may cut a 50 item form into five pieces and use it to give five, 10 item tests).

Then--here's the diabolical part--they cut the numbers off the side, so students don't know which range of items from the original form is being used. 

You can cut the numbers of and leave enough space to write numbers back in.  (i.e., from the original IF-AT form, you may slice off the numbers 10-20, but for the purposes of *this* test, the students can hand-write in the 1-10 in the little space left over.)

You have to keep good track of things for yourself, but it does give you lots of options.

Subject: IF-AT versions

Hi again,

I'm curious if anyone has had issues with students realizing that
there are only a few versions of the IF-AT forms? That is, even if you
switch versions of the forms from one RAT to the next, do students
ever realize that the pattern of answers might be the same as an
earlier form? My concern is that I will likely only have two versions
of the form and students will take five or six RATs so there would
have to be some repetition. I know I could get more versions by
ordering more forms but in order to get all five different answer
versions, I would have to order 1250 forms and it would take me YEARS
to use them all - but is that what most people do?

thanks,
Jennifer
