Doesn’t mention class size which is a top if not the top reason parents generally switch to private schools
This study is a bit old (2003) but it’s an interesting element to consider for why parents tend to be more satisfied with private schools

I”m w/ @BisforBerkshire-not having a K12 policy agenda is a cop out.  There are plenty of things Mamdani could do in addition to making schools greener or providing families w/health care, housing, etc.  Kids spend much of their lives in school & what happens there matters a lot.

People in the education-advocacy area, but also a lot of parents, are disappointed in how little @NYCMayor has done in K–12 compared to previous administrations as I pointed out to @niaprater of @NYMag

“They need to put together a real (class size) plan or they’re never going to get there and that involves aligning enrollment with class size as mandated in the law and building a lot more schools more quickly”

Bizarre –1st bonuses for teachers assigned to classes that don’t comply w/class size law &now bonuses for principals if they do? What if they don’t have the space – which DOE has done nothing to provide. None of this makes sense. NYSED should step in. nydailynews.com/2026/09/18/n…

Bill Gates on attending private school with small classes: “that was another piece of incredible luck. There were 15 kids in a class compared with 30 in public schools” So why’d he spend so much $ on bogus studies to show that class size doesn’t matter? thetimes.com/life-style/cele…

Reminder @nycmayor @ZohranKMamdani : the demand for smaller classes is NOT flat. Hundreds of thousands of NYC kids are being denied this. What is your plan to address this? Their right to a quality education does not stop at age 5.
Mayor Zohran Mamdani and Gov. Kathy Hochul join the toddler rope ahead of childcare announcement this morning. As Times reported, demand for childcare was flat this year despite Mamdani admin outreach surge: 99k offers extended for pre-K and 3k

Mamdani makes his upteenth announcement on 3K - meanwhile not any word on improving opportunities for kids in grades K-12 or what space provided for smaller classes. Parents are agonized waiting to hear which schools to be provided with that opportunity. nydailynews.com/2026/05/18/m…
