The Klingenstein Center for Independent International School Leadership

New York's educational research institute category holds 68 listings. 66 have a phone number on file. 65 list a website. That means you can call two or three and compare notes before you even leave your desk. Most entries cluster in 10027, which alone holds 17 of the 68. Smaller groups sit in 10003 and 10016, with a few more scattered across 10012, 10017, 10028, 10031, and 10001.

None of these listings carry a Sponsored tag right now, since this category has no paid placement active in New York. What you're browsing is plain database order, not a promoted lineup. If you run one of these institutes and your phone or website field is blank, you can claim the listing and fill it in. That one step saves someone in 10027 or a nearby zip an extra search before they reach out. SiteCity doesn't rank or endorse anyone here; it's just a record set organized by location, and complete contact details are what get you found.
