I definitely agree that more factors need to be in place when making a college decision but I do have a few questions. If this measure of impact is implemented, wouldn't students once again use this as a ranking system which it seems you are trying to get away from. There is also a lot of current competition in the student survey space with places like Niche providing a tremendous amount of data in regards to almost every aspect of college life. I'm curious how you plan on differentiating your product, and also catching up to an established competitor since this data collection will likely be a tedious process. It's also becoming more difficult to actually reach students and receive honest feedback without some kind of incentive process. As a college student, my email is flooded with messages asking for feedback or input that I ignore because I do not have the time nor the incentive to complete it. I'd love to hear about how you might tackle this problem.
I certainly think networking is an extremely important part of any potential career. I do have a few concerns about the idea however. Due to many alumni's busy schedules, it can often be difficult to organize large scale events where everyone is free to contribute their time without any defined incentives besides goodwill. If they were to help, they would also be looking to poach the top talent, thus creating a potentially difficult scenario or competitive atmosphere. I also think with the progression of LinkedIn many students already utilize that as their primary way of networking. Firms also hold these networking events/sessions, but a big problem is that there are far more interested prospective students than available mentors/firm representatives. I think it could be difficult to establish an optimal ratio for these events to take place since incentives are more heavily aligned with students than professionals.
I certainly find your project interesting and unique, but I still have a few reservations about the idea especially in regards to higher education. As a current college student, me and many of my peers are still unsure of what we want to do for certain, but have developed areas of interest that have become our major/minor/concentration. At this stage, I would find it much more difficult for me to try to define a problem I'd like to solve in this world, rather than delving into an area of interest and seeing what comes of it following internships, club involvement, etc. Also, for those of my peers who do have a certain specific problem in mind, they can tailor their education to help meet these goal, but will still require extensive knowledge in certain subject matters. It seems more likely they would find their problem after picking a major than vice versa.
Another question I have is regarding the measure of impact. For an impact to be made, it would likely require a significant amount of time, and I'm unsure how willing higher education would be to shifting their curriculum to even allow a test like this. I'm curious how standards such as the "grit" or "resiliency" you mentioned in your impact measurement could be attained. I think the current system of majors still allows for great flexibility in career and life choices and that asking someone to define their entire education in a single question is more difficult than it may seem.
I do really like the idea of having a defined purpose with education, but I think it would be better to incorporate it through the form of a club or organization that steadily gains traction. A lot of social impact curriculum in higher education seems to relate to the approach you outlined, but it is used as a supplement rather than a replacement.
