We look at the whole six years for the 'overall' of tenure. But when it comes down to it, we can only take into account the numericals of the last three years. This makes it possible for us to hire with three years accrued. Perhaps this is true at your school?
There is no written policy on this at my institution (though perhaps there should be). I would say that colleagues and the rank and tenure committee would be willing to take into account the individual's publications/conference presentations from the years previous to arriving here, as part of the candidate's general scholarly reputation. But they would want to see, by the tenure review, sufficient evidence of teaching excellence and integration into our culture of service during the time the individual has actually been here.
The person in the chair's role is important if the colleagues are acting like this. You have to keep going to bat for the person throughout the first year.
Yes, I have spent a good deal of time crafting a strong supervisory letter for this person's first review (at our institution hu will have a review every spring for three years, with the tenure review being the third) and had a strategy session with our dean, etc. I am also acting politically to break up the small cabal of disgruntled naysayers, etc.
you may actually want to deny tenure as you would have done elsewise at the third year mark.
I'm not sure I understand this. The candidate would have an option to "give back" a year of credit toward tenure, and thus postpone the tenure decision. I might advise that. But I would not want to deny tenure; this person is a great asset.
Many thanks!
