After assessing the skill level of the student, it depends on their satisfaction with their current method book. If the student is happy with their current method books, there is no reason to switch.
I have had both of my children enrolled for piano lessons in Ms. Cosgrove's sessions for many years now. I am deeply impressed with her teaching approach. She is passionate about music, teaches to the individual needs of the student, and communicates weekly with the parents on the progress of her students. She brings to the table a profound knowledge of educational procedures and techniques that make her much more than being a music teacher. I would highly recommend her sessions for anyone who wishes to pursue the instruments Ms. Cosgrove teaches.
