how many years of school for business/

Most full-time business schools are two years in length.  There are also part-time  or evening and weekend programs depending upon where you live.  I can share if you're interested in the latter.

You should find a college that has a Co-op program where you can take classes some semesters and undertake internships other semesters. That way, when you graduate you will have practical experience in business on your resume. Northeastern in Boston has a good program, but there are others.

Most business degrees will be four years for your undergraduate degree in some concentration in business. This can include accounting, finance, marketing, management, etc. Some people continue on to go through graduate school for either 1 or 2 more years right after their undergraduate program. This is only optional! I am an accountant, and started working just after 4 years of undergrad. I may plan to go to grad school later in my career.

In order to obtain a business degree, you will typically need to go to college for 4 years. This will allow you to obtain your Bachelor's degree in the major of your choice (i.e. Finance, Marketing, Accounting, etc.). I began working right after graduating from my undergrad of 4 years. I didn't need to continue pursuing a masters or graduate degree, but it is certainly an option. Oftentimes, professionals will pursue an additional credential later in life. Depending on your profession and where you work after college, your employer may offer some type of reimbursement for going back and getting your masters!

Most Bachelor's programs are 4 years long. Some schools have a 5 year program that give you the chance to do internships, or mini trials of a job. There are also Master's Degrees, which typically involve an extra year or two on top of your Bachelor's Degree. These are a great way to learn more about specific areas in Business and will help differentiate you from other applicants when you begin to look at jobs. The more you learn, the better the job options you have!

depends what you want to do with business. A general business administration undergraduate degree is typically 4 years. There is an option to go for a Masters degree in business, or a masters of accounting, which would be another 1-2 years of school, depending on what program you enter into.

To add to Megan's answer, there is also the option to take a master's program in a nights-and-weekends manner, which can span about 3 years. Santa Clara University is one example. This is the program I took and I found it very useful.

4 years for an undergraduate degrees, then an additional 2-3 years for MS or MBA degrees.

Most business schools are a four years for an undergraduate degree. Many schools offer a five year program, which consists of both an undergraduate and masters degree. Some schools offer longer graduate programs. The amount of years will also depend if you are going full time or part time, but typically a business degree is four years long.

An undergrad major in Business will take 4-5 years if you're looking for a college degree. If you want to pursue a Master degree this can be done in two years full-time, or you can do it at your own pace online.
