Where its students go next. The DOE lists Fiorello H. LaGuardia High School of Music & Art and Performing Arts, Brooklyn Technical High School and Edward R. Murrow High School as the high schools its students most often attend.
Fall 2026 admissions: families applied in fall 2025 for sixth grade in September 2026. Seats, applicants and applicants per seat are the DOE’s, from its Fall 2026 Middle School Data file on InfoHub (saved by the DOE 2026-09-18), the same figures MySchools shows as last year’s demand. The DOE counts applicants this way: “MySchools shows the true number of applicants who were considered for a seat in a program, meaning this number excludes applicants who matched to a more preferred choice from their application.” (schools.nyc.gov, read October 4, 2026). Applicants per seat is the DOE’s own figure, rounded to a whole number, so 0 means fewer than one applicant for every two seats. “All filled” is the DOE’s flag for whether every seat in that group was filled; “n/a” means the file gives no figure. Seats and demand change every year; this page does not turn them into a chance of admission.
In 2026 admissions, 351 of the 418 eighth graders at Mark Twain I.S. 239 for the Gifted & Talented who applied to high school sat the SHSAT: 84%, which means most of the grade took the test.

“2026 admissions” means students who sat the SHSAT as eighth graders in the 2025-26 school year and received offers for fall 2026, as in the DOE’s Fall 2026 SHSAT and Discovery Summary. “8th graders” counts the school’s eighth graders who applied to high school; “took the test” divides testers by that count when both are published. The district row adds the published counts of its schools, so its offers are a floor; the city row is the DOE’s own total. “Not listed” means the school is absent from that year’s file.

Your child is in 6th or 7th grade
A 7th grader sits the SHSAT in fall 2027; a 6th grader, in fall 2028.
The test comes in the fall of 8th grade, so there is no deadline yet, and that is the point: starting now leaves time to work on reading and math at a steady pace instead of in the last weeks. The counts above show what happened at Mark Twain I.S. 239, not where your child stands. We start with a scored official practice test, which does.
Your child is in 5th grade
Middle school applications are open until December 11.
Start with how many families applied for each seat last year: the DOE publishes it program by program. The middle school you choose is also where the SHSAT years happen, so ask the schools on your list how many of their students sit the test and how they prepare them. This school has talent test programs: registration to test closes November 2.
