Conestoga has once again defended its status as one of the dozen most-elite public high schools in the nation through the latest Niche.com 2017 Best Public High Schools in America rankings.

Conestoga’s A+ grade ranked it No. 12 in the country and No. 1 in Pennsylvania, based on state test scores, college readiness, graduation rates, SAT/ACT scores, teacher quality, and other ratings.

• 26. Downingtown East
• 33. West Chester Bayard Rustin
• 42. West Chester Henderson
• 46. Kennett
