There are literally hundreds of colleges and universities online who claim to offer legitimate bachelors and masters degrees that can be obtained from home. It is difficult to sort through all of the options.
A Handful of Companies Monopolize the Market - There are a handful of companies who offer online degrees that have spent so much money in marketing online to potential students, that it becomes difficult to find any other schools that offer an online education. Every search done ends up with results from the same 20+ schools. The schools that come up over and over are not necessarily the best places to obtain an online education. In fact, quite the contrary.
Reputation Matters...A Lot - A lot of the schools who advertise heavily online have a reputation as being "online schools" which means that whenever you go to apply for a job or further your education with graduate or post graduate schooling, you may run into difficulty in getting acceptance of your degree.
Employers may be more hesitant to hire you and graduate programs may be hesitant or refuse to accept you into their program.The Great Schools Are There, But They Are Hard To Find - There are actually over 100 other "brick and mortar" schools that offer online degrees, but they are difficult to find online because of the heavy advertising of the 20+ schools that are seen everywhere.
Take the time to find the reputable colleges and universities that offer degrees that will look to your employer that you took your classes on campus just like everyone else.
