Main Factors to Consider When Choosing The Best Business School for You

Does the school offer the degree you want? (e.g., MBA, MAcc, EMBA)

Is the tuition affordable?
Are the school's graduates successful in landing the types of jobs you'd like to land yourself? 
Is the curriculum as broadly or as narrowly focused (or as flexible) as you'd like?
Is the class schedule flexible enough for you to meet your other commitments?
Do the accommodations (classrooms, media centers, libraries, housing facilities, etc.) meet your needs?

Additional Factors that Make a Business School Desirable
Is the school known for the high quality of its programs and graduates? Rankings lists can help you determine this, even if a business school isn't top-ranked, it can still have a good reputation.
Does the faculty possess extensive education? Are the faculty members considered to be leaders in their fields?
Are the class sizes small? Is the student:teacher ratio low?
Are the professors committed to teaching? Are they available outside of class?
Does the school have a Career Placement office that actively works to assist graduates in finding internships and jobs?
