The city's pre-k program has seen 37,000 families sign up in the first week of enrollment this year.
That's more than double the number during the same period of 2014, the inaugural year of universal pre-k.
City Hall has been running print, radio, and subawy ads, and credits wider awareness of the program for the increased signups.
Mayor Bill de Blasio set an enrollment goal of 70,000 for this year.
Families have until April to sign up for programs starting in September.
