Signed, the guy who has mentioned numerous times he went to Sayreville High School and obvious done well for himself.
Funny thing about that - 35+ years ago, SWMHS was a model institution, academically. When I got to college, I had three advantages: four years of prior military service, a full-time job and a Sayreville education. The latter prepared me, academically, in a manner that's lasted a lifetime.
So yes, public schools CAN work for kids that are motivated.
But by the same token, public schools have changed dramatically, as a whole, these last three decades. The teaching methods are too constrained, there are too many teachers who are just phoning it in and they all seem concerned about half a dozen things more than they're concerned about actually teaching. Plus, a lot of them (including my local FRHSD school, which is Manalapan) are total zoos.
I remember the first time I went on a first aid call to MHS during the day. We went into the administrative offices and along the way observed dozens, if not more than 100, kids just milling around. In the hallways, outside... I asked the assistant principal if they were between classes. He assured me they weren't.
The problem, he said, was that you can't discipline the kids because the parents flip out. Up to and including bringing legal action against the district. So they've given up trying to enforce against minor infractions and concentrate on the serious stuff, which is almost all drug-related.
So I sent my girls to SJV. We could afford it, and the school claims a demonstrable ROI - they track in great detail the college scholarships awarded to their graduates and they freely share the data.
The oldest one graduated with honors and went to UDel - because it's one of the few schools in this part of the country that had the program of study she wanted. She's now going into her second year of graduate school at Sacred Heart, for OT.
In her case, we felt private school was a benefit because she's a lot like me - she's easily distracted and often not in a good way. She had a great circle of friends, stayed out of trouble and as a bonus got to run cross country and track in the most competitive group in the state. The sum total of her experiences gave her the confidence she needed to get where she is today.
The younger one is completely different - bookish and introverted. She would have excelled, academically, anywhere. But socially she would have been lost in a school with a 3k+ population. At SJV she found good friends, got involved in extra-curriculars and graduated with a 4.67 GPA, 4th in her class.
In her time at SJV she took 7 AP courses (and got 7 scores of '5' on the exams) and 3 courses that are offered with joint credit with Seton Hall.
She just finished her freshman year at Dickinson College and the merit money they gave her has paid for her SJV education several times over. And they gave her credit for 9 classes; according to her registration profile, she started school as a sophomore.
As most people know by now, Dickinson ranks pretty high on the list of snooty, expensive, northeast liberal arts colleges. And she loves it there.
Most of Dickinson's students come from private schools.
The point is (and I know this kinda brings the thread full-circle) that if you can swing it, private schools are a definite benefit. The manner and extent will depend almost entirely on the individual. Yes, your mileage may vary. But nothing can convince me that there are not very significant advantages bestowed by a private school education.
Apologies for the long reply.
