The biggest drawback to a 2 year college compared to a 4 year college is inherent in the distinction: two-year colleges do not award bachelor’s degrees. That means, unless you only need an associate degree or some specialized degree obtainable at a community college, you will need to transfer to continue your education to a four-year college.
However, this is not a huge concern. In order to make this process easier should you choose a community college, check to see if the college has an agreement with other four-year institutions. For instance, the Illinois Articulation Initiative (IAI) is a statewide agreement which streamlines the transfer of general core classes between participating institutions. Such setups and research can go a long way to the confusion surrounding which classes will transfer and which will not.
