Dean complains about helicopter parents at Stanford and yet admissions essentially requires incoming students have helicopter parents. To get into a school like this you need to be exclusively focused on exactly the arbitrary criteria that will get you accepted into a school like this -- grades in the "right" classes, enough sports to talk about it in an essay but not too much, extracurricular and volunteer work at t…
The classic example is the parent who goes into the school and harangues the teacher when their student gets a bad grade on an assignment. A demanding parent communicates their disappointment with their kid, not the teacher. A demanding parent lets their kid fail and then delivers consequences. Overcoming failure is how people develop motivation and mental toughness.
Stanford (and Harvard, MIT, CalTech, etc.) have been hard to get into for many decades, and students got into them. Helicopter parents justify their coptering with the sentiment above, but that doesn't mean it's true. You don't need to helicopter to have a high performing kid.
And not every kid is going to perform at the top level, and IMO a good parent needs to be ok with that. I think when the parental expectations don't meet reality, that's when helicoptering can start.
