My DCs do not attend public, but I did a lot of research on districts before settling in Westchester. Public school rankings are based on test scores. The fallacy around public school rankings is that some schools have economic diversity or a population of ESL students that bring down test scores. Thus, those schools score lower, without accounting for the quality of the teaching or how well resourced the district is. Greenwich, specifically, has an Advanced Learning Program in elementary and middle school. It's a well resourced district by every measure. Darien, New Canaan and Westport are more uniformly wealthy and thus the scores reflect that. A student can receive an excellent education and EC's in any of these districts.

I can't claim to know Greenwich well but is your heart set on Greenwich? If you're willing to go a little farther in I think it's generally accepted that Darien, New Canaan, and Westport have better schools than Greenwich does. (Wilton and Weston and Ridgefield more debatable though they're also highly ranked)

Does anyone have a good, recent understanding of Greenwich CT public schools? I understand North Street School is the best. But how much better is it than, e.g., Dundee or North Mianus? Cos Cob used to be working class - is that still true? Is there any benefit living in Glenville school district over just living in Pelham for example? Thanks! We are NYers looking to move to CT.
