City public schools have been open for more than a week, but plenty of students are still trying to find their seats.

In a system of nearly 1 million children, the job of enrolling students continues well beyond the first day of class.

The Education Department operates 19 enrollment sites called Family Welcome Centers, like this one at Brooklyn Tech High School.

The scaffolding is foreboding, but a friendly employee stationed out front ushers in parents and children seeking a school placement.

Some students in this process moved to the city over the summer. Others are entering public schools after attending private school or leaving school all together — like Regina Wright's son, Dijon.

"My newly turned 18-year-old son has decided to continue his high school education and bring me that diploma that I've been asking for so I can place it on my wall next to his sister," said Wright.

Wright had been looking into online alternatives for her son - but he decided he'd rather attend class in person.

"He informed me that he wanted to be around his peers, so he said he wanted to return to high school, and I'm behind him 100%, so here we are today, to get that done," said Wright.

The Brooklyn Tech site is one of 15 enrollment sites operating year-round, with 107 full-time staffers; but four others are added for August and September, with 180 part-time workers, to make the process easier during peak enrollment season.

Since August 26th, the sites have logged 24,500 visits.

Enrolling isn’t always seamless, one parent tells  NY1 a center referred her to a school that had no seats for her child, who was returning to the system after two years in private school.

But another parent, Samantha Smith, says the employees helped her find a good fit for her 16-year-old daughter, who wanted to transfer schools.

"They went forward, moved forward and found me something that works for her," said Smith.

The enrollment centers are open from 8 a.m. to 5 p.m., except on Fridays, when they close at 3.
