Applying to graduate school involves the following steps:
Graduate students can obtain funding from several sources to finance their education. This might include, but not limited to:
Graduate students will need to identify a supervisor either at the beginning of their program or just before they start their research project. In cases where students have aobtained research funding, the supervisor will be the Principal Investigator or one of the research team members of that research project. Self-funded students and Students who obtain program/department funding may not need to identify a supervisor until they complete their coursework. It is obvious that students should identify supervisors who will positively support them through their graduate studies. The student-supervisor relationship is a very important one and can easily influence how well a student performs. Supervisors also influence a student's career quite significantly in developing career networks and also depending on how much infleunce the supervisor has in the research feild and industry.
At some point during a student's program, they will need to set up a supervisory committee, Each uniersity has different requirements for the composition of this committee but usually you will need about three researchers, of which at least one of them will be external to the department. And in some cases, at least one member of the committee will be external to the university. Again we can't emphasize enough the need to ensure students select supportive supervisors.
