New-to-BPS applicants for Kindergarten and any students enrolling in Grade 6 or Grade 9 should register in the first registration period in January. All other new-to-BPS applicants should register in the second registration period in February. School assignments are made after each registration period ends, using a lottery system, so it doesn't matter when you register within a particular period -- it's not first-come first-served and everyone has the same opportunities as long as they register within the earliest period. The full schedule is below.
