My daily Google search for Piedmont picked up the City of Palo Alto announcement that their K-12 district is now fourth in California, after San Marino, Canada, and Piedmont. Go Highlanders!
The three elementary schools in Piedmont ranked exceedingly well in the 2009 Academic Performance Indices: Beach-971, Havens-927, Wildwood-964. PMS's API was 930, and PHS's was 904 (an eight-point drop compared to the previous year, by the way). Five high schools in Alameda and Contra Costa Counties bested Piedmont High (though of course scores wobble up and down each year): Mission San Jose in Fremont, Oakland Charter High (a tiny school on 12th Street downtown), Campolindo and Miramonte in Lamorinda, and brand new Dougherty Valley in the Windemere neighborhood of San Ramon.
