COACHE is a product of Harvard’s School of Education. One of its main outputs is a survey that is taken by faculty and then analyzed by COACHE. As I remember, the survey gives one standard assertions such as “The administration of this university strongly supports interdisciplinary research” and then gives one an option of five answers from “agree very strongly” to “disagree very strongly”. (Or at least something much like that.) One great thing is that the score the university gets is a comparison with what are counted as peer institutions. So if your university is ranked in the bottom third in interdisciplinarity, for example, that is not simply because you have a lot of malcontents. Rather, it is because your faculty are much more negative about that feature than most of the faculty in your peers. And that becomes a problem for the university.
If you are on the job market or if the tenure decision is coming near, do think of asking if your (prospective) university has a COACHE report, and ask to see it. (Those applying to grad school may also benefit; see the next para.) At least the one for my now former university reveals two things: (1) major weaknesses and (2) differences between tenured and non-tenured (tt) points of view; see below for a remark about this. If you want to dig a bit deeper, it may also show you more general facts about the university that are holding the problems in place. In my experience the report is stunningly accurate. That is, the university ranks low on features that, to be perfectly frank, drove me crazy. The faculty, however, love the upper administration, a fact that shows a very important disconnect.
TENURED VS. NON-TENURED points of view. In my former university the tt are generally more positive than the tenured profs. It would seem easy for the tt also to be much more negative, as I would guess they are in some other places. In any case, there are contexts in which this won’t matter, and ones in which it will. If a set of discontented tt faculty have been bullied into being enthusiastic for prospective grad students, those who believe them may be in for a shock. Equally, if the tt folk are much happier than those with tenure, they may not be a good source of information about whether you should join the department as a faculty member. Now the COACHE report does not mention specific departments, so differences in these respects are really just warning signs.
The differences between tenured and tt points of view are interesting, and I don’t really know what explains them. When I was following the literature on sexism in STEM quite closely about ten years ago, it appeared that STEM women did not perceive the sexism until the tenuring process started. One can think of a number of possible reasons for this, and some of them would spread across genders and disciplines. Perhaps, for example, some senior faculty feel protective about the younger ones, and smooth things out for them a bit. Another might be that the tenured faculty may try to draw on more resources, and so discover what the weaknesses are. On the other hand, it would seem most unfortunately easy to make the tt faculty miserable, so differences in directions different from those at my university would seem to be more understandable.
