Fees definitely vary by program. Any CSDCAS schools have application fees built into the CSDCAS application. However, if a school has a supplemental application you may have to pay a fee for CSDCAS and the supplement (I did). However, one of my schools waived the application fee if I attended an online information session. Some schools may have priority deadlines with cheaper fees. In my experience the typical fee was around $60, but they ranged from $0 to $125. All this information should be somewhere on each program's website.
