Good morning Mike (it is morning in this part of the word!). 
I also have access to item-level data (but as I said, it is not possible to use similar items from one year to the next). 
Thank you so much Mike for your email.

Iasonsas, thank you for asking for our assistance.

Do you only have access to total scores on the tests, or do you also 
have access to any response-level data?

Mike L.
