Deadlines
You may apply to both ISP and Northwestern under either early or regular decision. Please note that early decision to Northwestern is binding. In either case, you should carefully observe both NU and ISP deadlines below. ISP will consider applications received after the deadline, however applying late will put you at a disadvantage due to the limited number of spaces in ISP.
*Early admission decision and applicant decision deadlines have been moved back one week. Thank you for your patience.*
