Thank you everybody for offering me so much help on this issue. The truth is that I received tens of messages from all over the world, but I would like other to contribute as well, if they have not done so already.
<br>It seems that there is much interest, and the trends are the following:
<br>* excellent idea to have an open ended item bank accessible by everybody for high stakes exams because it makes securityu issues non existent, the quality of the items can be monitored, the candidates know what they will face etc.
<br>* item calibrations make no senese since item difficulties will drift immediately
<br>* a backwash effect is expected and teachers will probably teach to the item bank
<br>* the results/scores of the candidates will be inflated (they will have the chance to memorize responses)
<br>Have I missed anything? Please remind us.
<br>I will also try to think whether anyone else is using such a thing in practice, and I'll make a literature review.
<br>I think this is progressing to a journal article. Does anyone think that this is a good idea? Does anyone think that I should not spend my time writing such an article because there may not be enough interest by the audience or the editorial boards of journals? Which are the journals that would be more likely to publish such a think?
<br>Please help me to 'interview' experts in the fields - please suggest names.
<br>you have been really helpful. I hope you will help me more.
<br>P.S. Apologies for hijacking the Rasch list. If not appropriate, please let me know.

<br>Another thing Iasonas:
<br><br> Once you have an "open" item bank, is it useful to calibrate the items? the difficulty of the items will ve reduced, even most of them will be solved by mostly all people...so the initial calibration has nothing to do with the original calibration.
<br><br> This is another important topic to discuss.
