GBS will provide the opportunity for interested junior students to take the PSAT/NMSQT on Wednesday, October 11, 2023.  The PSAT/NMSQT is a 2 hour and 45 minute test that measures the reading, mathematics, language, and writing skills essential to college-level work.

The PSAT/NMSQT serves two main purposes:

1. It is a practice test for the SAT. Glenbrook South will administer the SAT to all juniors on Wednesday, April 10, 2024. (Please note that scores earned on the PSAT/NMSQT are not used as criteria for college admission.)
2. The National Merit Corporation uses the PSAT/NMSQT as the qualifying test for all students who wish to participate in its nationwide scholarship competition. Students who score in the 99th percentile of the PSAT/NMSQT qualify for this scholarship competition.

Interested students may register online.  Online registration is completed through the Power School e-Funds Payment Portal. Select Exam-PSAT/NMSQT under Optional Fees.  The fee is non-refundable.

PSAT/NMSQT fees are waived for students who currently receive financial assistance.

• Test Date: Wednesday, October 11: 8 a.m.–noon at GBS. Please note, that this day is a late arrival day for all other students.
• Fee: $20.00 (non-refundable)
• Early Registration Deadline: Monday, September 11, 2023
• Late Registration Deadline: Exams are limited. Registrations after Monday, September 11, 2023, are accepted on a first come, first served basis depending on exam availability.
