I argued that, in many cases, the student had no chance of making it past the first year and that we were just taking their money and wasting their time. Privately, I tracked those who I said we should not admit, but was overruled by the rest of the committee. As I recall, just under 95% of those who I thought wouldn't make it through the first year didn't. Most were minority students. At the end of my term, I presented the stats of our record for the previous two years confirming my suspicion that we were deluding too many students with our "false" acceptance.
To my knowledge, the university did not change its policy standards.
You're lucky you kept your job. The man behind the green curtain does not like to be mocked.
