<p>You need to do a FAFSA for each of your college bound students (a different one for each). Parent uses the same PIN on both. Each student needs their OWN PIN. You do two separate forms...each student puts their own financial information onto their FAFSA, as well as the parent info. Yes, your daughter needs a PIN....that is how SHE signs her FAFSA (she can't use her brother's "signature").</p>
