Things to consider when deciding to apply to graduate school:
Finances - How much will it cost to attend graduate school? How does it meet your career goals? Is it necessary? Is it worth it? How will you pay for school? Could a current or future employer pay or offset the cost of graduate school to make it more affordable?
Location - Will you need to relocate to attend graduate school? Is this feasible? Should you consider online graduate programs? What are the pros/cons of online programs? Is an online program right for you and how you learn?
Prerequisites - What are the prerequisites for admission to programs of interest? Do they require that you have taken certain courses before admission? Do they require completion of an admissions exam such as the GRE or GMAT?
Motivation - Why do you want to attend graduate school? What do you hope to get out of it?
