I agree. The public schools here are a farce, although there are kids that come out of them with some good skills. Pretty much all the public schools here that I've seen (in Lima, anyway) can be compared to the worst of the inner city schools in the US.
But you don't have to go to the extremes. You don't have to pay $1000 a month to get a good education here, and a lot of people seem to think that this is so.
I've heard extremely good things about Nival A in Surco
. Colegio Trilce
has campuses around Lima and a very good reputation. We were going to put the boys there, but I wanted smaller class sizes. Depending on the campus, it's around $150-225 month.
Circulo de Ingeniera - where my boys are now - about $125/month, with an excellent curriculum. (sorry, they don't have a website)Friendship High School
in San Isidro - love this school, almost went here instead of CdI, about $150/month.
My point is that when you're comparing prices, it's not black or white in each case. if you're in the US and want to eat all imported foods, your grocery bill is going to be much higher. Same here - if you want to keep eating all the same things you're used to from home, you're going to pay a lot more for all the imported stuff.
Gasoline is more expensive here - buy a car that's converted to LPG and save money.
If you want to put your kid in one of the most expensive schools in the country, it's most likely going to be more expensive than back home, unless you also had your kids in an upscale private school. But choose one of the mid-tier schools, the prices are quite affordable and your kids still get a very good education.
