Check to see how much the school's tuition is or how much each credit unit costs. You may also check to see the college's financial aid packages. Will their financial aid cover students who choose to get their degrees on line?
Check the admissions requirements for each accredited university you are applying to. Each school may have different requirements. Also check to see if you need to have a particular undergraduate degree to apply for a graduate program. Some schools also require you to have taken the GRE (Graduate Record Examination) to ensure consideration during the admission process.
Verify that the university's course of events fit into your lifestyle. You can check to see if the school runs on a semester or quarter system. Quarters tend to be faster paced, while semesters can allow you to spend more time on one particular subject. You also need to find out if the school needs you to physically be on campus for any particular graduation requirement for any class. If you want to only be a student part time, check to see which programs allow you to do so.
Check to see if the school of your choice even offers a specialty in network administration. Even if it seems like the right choice to you, a school may be a poor fit if they don't offer enough online coursework in network administration.
Look at the college's website to see if the network administration degree requires you to complete the program in a rigid time frame. Think about if this particular schedule can fit with everything else you are involved with.
Plan ahead to see if you might need a certain computer program for a particular class. Some professors may require you to do your homework on a particular program for credit. If you don't have the program, think about having to be on campus to use their computers for this task, or having to purchase the program.
Begin the application process. It may help to make a spreadsheet of all the due dates; each institution has a different deadline for things. Remember the GRE may also be an essential factor to your application process, and certain schools require a minimum score, so enrolling in a prep class or studying for the test on your own would be preferable. Also consider that each school may have an application fee, which can get overwhelming if you apply to numerous schools at once.
