Great question. I was approached by an ITT recruiter years ago and contemplated about the same things. I'll give you my take on ITT schools and then talk about the path I took to lower the cost of college.
ITTs are very specific and straight-to-the-point schools. There is nothing wrong with them per-say, however, getting a full college degree is still highly valued in the work force. I would suggest shadowing someone who goes to the ITT schools, rather than taking a tour. This way you will get a honest look into the realities of a technical school, and not the tailored experience to get you in the door.
My parents are low-income and seeing them struggle with money, made choosing a school and not having a big debt a concern of mine. Since I had to pay for school myself, I had to be strategic about every thing I did, leading up to graduation from college. What I did was went to a local city college (SFCC) to finish all my pre-requisites (English, Math, Public Speaking, etc), then I researched to transfer to a State Universities (SJSU) that specialized in the field I wanted (Design). This wouldn't get you out of school quick, like the months ITT schools guarantee and promise, but you get a more well-rounded education. Most companies in the Silicon Valley, value high education, so anything ranging from State to Private schools are still a big thing. You might want to check out LinkedIn's new universities pages: https://www.linkedin.com/edu. They give you an idea of where people went to school and where they work at now. It's super insightful.
I was able to finish college with $0 debt, but only because I worked during the whole time, applied for EOPS, grants, and scholarships and had FAFSA. All these things helped me finish college and will help you too! Hope this gives you some insight.
Dream big, Vivian
