Carpentry is an excellent field to get involved with right now! Any of the trade fields - electrician, plumber, carpenter, construction worker, roofer - are all excellent fields to go in. They do not require a 4 year degree but often the starting salary is significantly higher than the average 4 year degree college graduate. I would research technical and trade schools for a great place to start. Trade careers also often will require an apprenticeship. There are even apprenticeship opportunities available for high school students. Check out this opportunity in your area and consider applying: http://www.techboston.org/techapprentice.html. Trade careers are great because you can enter the workforce right away. Over the next 10 years, job openings in carpentry are projected to increase by at least 27%.
if you are interested in getting a 4 year degree, start researching careers like civil engineers, architects, and land surveyors.
I don't know if this answers your question, but a lot of tech schools have some great carpentry programs. I think to progress in a trade such as carpentry, its more about networking and finding apprenticeships after and during college. A little research also pointed me to a college in Nevada that has good reviews for carpentry. Check it out here...http://www.csn.edu/pages/4852.asp
