The deadline for D.C. high school students to enter the city’s new enrollment lottery for both traditional and charter schools has been extended one day because of a technical glitch with the lottery Web site, officials said.

The deadline for students to submit their online applications for admission to city high schools was originally Monday at 11:59 p.m. But users began encountering problems with the Web site at about 2:30 Monday afternoon, said Sujata Bhat, project manager for the lottery.

“Some applications continued to be submitted, while other applicants experienced slowness on the site, or saw an error message,” Bhat said. “There was no impact on any applications that had already been submitted.”

Lottery officials extended the deadline 24 hours to 11:59 p.m. Tuesday and notified parents of the change via a notice on the Web site and e-mail and text messages.

The deadline for early childhood, elementary and middle school students to enter the enrollment lottery is March 3.

For the first time this year, most charter and traditional schools have joined in a unified lottery meant to streamline an enrollment process that can be chaotic and confusing for families and school administrators alike. Previously, the traditional school system and each charter school held separate lotteries.
