The city has begun notifying tens of thousands of families where their 4-year-olds will attend pre-kindergarten classes this fall. While many are getting good news, thousands of families might not be thrilled. NY1's Lindsey Christ filed this report.

Last June, Mayor Bill de Blasio hand delivered a pre-K acceptance letter to a 4-year-old standing in for the 50,000 enrolling in the first year of the mayor's signature initiative. 

Now, the city is hoping to enroll 70,000 by September. To symbolize the program's growth, quadruplets played alongside the mayor Monday before being ceremoniously presented with offer letters.

"We are proud to offer a pre-K seat at P.S. 5 to Minerva Capellan!" de Blasio said.

Officials say more than 69,000 have already applied, and most families should be happy with their offers.

"Seventy percent got their number one top choice of location for their child. Eighty-two percent got one of their top three choices," said the mayor.

Roughly 10,000 families, or 15 percent, are being offered slots in programs they didn't apply to because their favored programs were full. 

The city says it will call each of those families individually and work with them to find a solution.  

"There will be additional seats available and further opportunities for parents to get the kind of match they're looking for," de Blasio said. 

The Capellan siblings are the only set of quadruplets who've applied to pre-K this year, but they're joined by 22 sets of triplets and more than 1.100 sets of twins. Their mother says she is grateful for the free program. 

"It is very expensive to take care of a school for my children," said mother Lenny Cappellan.

Meanwhile, the city says it doesn't yet have any results on how the first year of the mayor's pre-K expansion has gone. They are evaluating both the Department of Education's overall systems as well as individual programs and the mayor says his administration will be very transparent about those results as soon as they're available. 

The second round of pre-K applications begins June 22, and officials will be working to recruit a few thousand more 4-year-olds in order to hit the mayor's enrollment goal by September.
