First off, I don't think that whether a parent is an alumnus should be a factor (positive or negative) in whether a child gets a place at an Oxbridge college. Equally, I don't think that whether a parent is a donor to the college should be a factor.
However, I want to ask about the specific case where a child of an alumnus applies to a college. Is there any possibility that the college will look at whether the parent has donated to the college and that a failure to have donated will count against the applicant.
The background is that I did a one year taught postgrad at Oxbridge. I liked the faculty I was studying at and have made a number of donations to it. I didn't have a great experience with the college - I found quite a bit of soft discrimination as a non-British non-Commonwealth student (this was 1990s) and I've never felt like donating, despite several requests/calls a year. However, my spouse is worried that, in the (very unlikely) event that one of our children ends up applying to that college, it would count against them, and thinks that I should donate.
Does anyone have any experience / thoughts on this? Sorry - I know that it is the epitome of first world problem.
