Top tier publications for job application in the Czech Republic I am asked to provide my Tier 1,5,10 and 25 publications for a job application in the Czech Republic. Is there any standardized way how to interpret this? Does this refer to journals with impact factors > 5, > 10 etc. or does this rather refer to the number of citations for each of the relevant publications?

Maybe somebody can clear this up for me.
Thank you in advance!
I finally got a response from them. 

They asked me to provide the publication counts according to the journal impact factors or actually ranges of impact factors [1:5[, [5:10[ etc. One of the options I guessed anyway.

Maybe this still helps somebody in the future.
