Anecdote of one:
My friend’s tall, pretty well dressed daughter went to the first day of computer programming at Big State U. The instructor announced while looking straight at her, " This is programming XXX. Those of you who are in the wrong room, this would be a good time to leave." She stuck it out, did well, but never took another programming class.
Regarding LAC’s: both my daughters have attended top LACs. Lots of good mentoring from women (and at one college Latina professor) and oldest is in a top PhD program. Latinas in grad school sciences are rare.
For both of them, getting good summer research and internships has been key to diversifying their experiences and getting additional mentoring.
