There are very few, if any, accredited colleges in NYC that will accept students *without* a high school diploma or its equivalent (GED). While some colleges may have alternative admissions pathways for students who didn't complete high school in the traditional way, these pathways typically require demonstrating academic readiness through other means, such as a successful completion of a GED or equivalent test, or a portfolio of work demonstrating equivalent skills.
Colleges are accredited and regulated, and they need to maintain certain academic standards. Accepting students entirely without evidence of high school-level education would severely jeopardize that accreditation.
If you haven't completed high school, your best path to college in NYC (or anywhere) is to first obtain your GED or complete an alternative high school program. Once you have that credential, you can then apply to colleges.
