You can apply online for public prek here from March 4 - April 5.

For more info and the prek calendar here.
In my quick perusal of the procedures, it looks like everything is the same as last year. You should contact each individual school for tours and for information about how the school will handle a wait list (if they have seats left over) in June. The one difference is that if you attend prek at a school that is outside your zone, you have a slight preference over regular outside of zone families to attend that school at kindergarten.
A very quick and inaccurate survey of new programs from the directory this morning:
PS 10, 107 and 321 in District 15 no longer have prek classes.
Some of the schools below (and in the directory) may have more seats than listed. They were added after the directory went to press.
In District 13 AND 15:
PS 133 has additional seats
the new PS 118 has seats
In District 14:
PS 84, PS 110, 196 and 250 all have more seats than last year.
In District 17:
PS 705 and New American Academy have seats.
