I am actually astonished that this is the first time something like this is tried in the US. And I also don't understand the negative comments here in HN

Specialized high schools are moderately common in the United States, some organized as general public schools, and some organized as "charter" schools (a form of regulation in the United States with public funding, but less public funding than most schools, and some variation in regulations that apply to general public schools). In my part of the United States, Minnesota, there is public school open enrollment (any student can enroll in any public school district, anywhere in the state) and quite a few charter schools (Minnesota was the first state to have any charter schools). My public school district receives students from forty-one public school districts, the farthest one more than 100 miles away. (I've heard that the child stays with relatives during the school week and goes back to his parents' home on weekends. That is perfectly legal here in Minnesota.) There is another charter school, far across the metropolitan area from where I live, that purports to be a Math and Science Academy.

But as I think any European or east Asian reader of the school's website will soon recognize, the Math and Science Academy charter school in Minnesota does not have a credible academic program in mathematics or science up to international standards. (One of my good friends had a child in that school, and she is bitterly disappointed by how much the school killed her daughter's interest in mathematics and science with its underchallenging curriculum.) A regular public school in Minnesota is permitted to have an internal program that is academically selective, for example a "school within a school" for gifted students, as my local school district does

and as other Minnesota public school districts had first.

By contrast, charter schools in Minnesota cannot be academically selective in any way, but must accept all applicants (which is also the plan for the New York City school in the submitted article), allocating spaces by lottery if the number of applicants exceeds the number of spaces. That is one of several ways in which regulations on charter schools are more restrictive than the regulations on regular public school districts.

Minnesota has a specialized program for mathematics only

that draws in students from all over the Twin Cities metropolitan area for classes at the University of Minnesota. I like that program a lot. My oldest son is an alumnus, and I will have two other children take that program's qualifying test in a few months, for two different entry points into that program.

In general, the cultural attitude in the United States is highly hostile to advanced programs for bright learners, as you can see in some of the comments here. Many programs for "gifted" students may not even have added value for academic growth,

academic achievement even in wealthy school districts is often below the standards achieved in poorer countries,

and the United States especially lags behind in teaching mathematics to its most advanced students.

So I'm glad to see the New York City experiment in offering a software engineering high school, and will be curious to see if that example is imitated in other parts of the United States.
