NYC High School Application Deadline Extended After Prediction Tool Glitch

A technical error in a new admissions tool affected odds for two Manhattan schools, prompting deadline extensions for thousands of families.

A glitch in the NYC Education Department's 'chance of offer' tool provided incorrect admissions odds for NYC Lab School for Collaborative Studies and Millennium High School.
The tool, developed with MIT, calculates students' odds based on criteria like lottery numbers and school competitiveness but used incorrect seat availability data for the two schools.
The application deadline for all high school applicants was extended to December 9, with affected families given an additional extension to January 10.
Roughly 1,600 families were notified of the error via email, and officials assured that the issue has been resolved and admissions results will still be released on March 6 as planned.
This is the latest in a series of technical issues with NYC's school admissions system, following delays in middle school applications and prior glitches in remote learning platforms.
