I graduated from a Canadian HS at 16 and finished at a T20 in 3 years. I was independent, mature, driven, and very ready to leave home. There were aspects of my college experience that were odd due to my age - but none that were so challenging that I would not recommend the same path for others.
I would, however, strongly urge your D to (1) look at schools with access to excellent public transportation as being a new/inexperienced driver in a new city can be scary (2) take full advantage of any opportunity for a junior semester/year abroad, even if it throws off the sequence of her ‘major’ classes needed for graduation in 4 years - she has the luxury fo being able to graduate in 5 years and not have anyone question the slight detour (3) if she is given the chance to go directly from undergrad to a grad program OR to an internship program - DO IT! I thought it would be easy to get a good/standard first job right out of college but it was very difficult to convince employers that a 19 year old could hold her own in the workplace (granted this was 30+ years ago). Not surprisingly, the best offer was from the cyber/tech world - where an internship turned into a paid position within a few months.
As a parent, I would suggest that you help her find schools with good advisor programs - my school had a wonderful residential system and an excellent academic advisory system. In addition, you should probably be ready to co-sign/investigate alternatives for a lot of one-offs that are not easy to do independently when you are under 18 (health care insurance), 21 (apartment leases), or 25 (car rentals).
I wish her all the luck and success - and you all the joy of watching her take this next step.
