Like all college questions, this is pertinent and important. There are many questions you need to ask yourself in order to answer this question! Do you have serious financial concerns? Are you completely undecided about what you may want to major in? Are you short course credits, or did you perform poorly in school? Did your high school have limited options that made it impossible for you to take competitive level classes, like Honors or AP? Are you returning to school and have to work full time?
Community colleges today offer many opportunities for students, even while they are still in high school, to explore different employment and educational options. For example, there are several opportunities to enter the world of hospitality management with a two year degree. And for those students who are not sure what they want to do, these types of community college courses also come with experential learning opportunities, such as internships, that can help you develop an area of interest. And if you are working, taking one or two classes in a community college during the evening allows you to engage with other students like yourself that are not always available to you in on-line courses, while also giving you an education that is convenient for time and location considerations.
Some community colleges can also help families manage financial considerations. For example, you can take one or two years worth of general credit classes, and then transfer those credits to another university or college for your junior year, thereby reducing or even eliminating some of the attendant debt load. Of course, some students also have very real concerns about their grades in high school, or the types of classes they took while in high school, feeling that these might not "look good" to a college admissions counselor. If you are not interested in being an "academic" and are just looking to get a decent job, then community college may be the best answer for you. On the other hand, if your grades were not as good as you would have liked them to be and you do want to pursue higher education, a year or two of community college can give you the credentials you need. This might also include helping you develop better learning habits that you did not develop in high school. Some students even pursue the community college route while they are still in high school, especially during the summer months, to "make up" classes or supplement what they already have (such as learning a foreign language or taking an AP level class).
Whatever your reasons for selecting a community college, consider that there are more options than not! It is up to you to find the options that make sense for you.
