I heard that there were 19 1st grade spots at NEST last year. Parents didn't like the commute. And there are mixed reviews on what happens in the regular G&Ts (citywides are accelerated and will accomodate pullouts for math -- heard the teachers tell me this on tours). The regular G&Ts are not accelerated but I do know of a 1st grader at PS 9 whose teacher is giving her 3rd grade math but that is the teacher. Don't know what will happen next year. The girl was waitlisted for Hunter and the mom thought she might get a spot. Now the mom is very frustrated.
If you take the OLSAT and take TAG or NEST, you might have a teacher that acoomodates. I would take those options for the curriculum, though TAG is not an appealing school because it shares the building with some tough "east harlem" type middle schools.
