<p>The OP is exaggerating on the 5000. There are no non-charter public high schools in IL with that many students.</p>
<p>However, both New Trier and Stevenson have over 4,300 students and they are both ultra-competitive high schools (amongst non-charter public schools). They send a lot of students to the most selective schools every year. Stevenson, for example, sends about 20 kids to Northwestern every year. That’s enrolled, not just accepted.</p>
