I looked up the CA state Academic Perfomance Index (API)rankings of a few of these schools. If you couldn't guess, they all suck:
Montebello: 30 percentile
El Rancho: 50 percentile
Pioneer: 40 percentile
Whittier: 50 percentile
Marshall: 50 percentile
Blair: 30 percentile
Pasadena: 50 percentile
The other item they all have in common: large % of hispanic enrollment.
Do you have the URL for that handy? (If not, I'll head off to GoogleLand.)
And probably a 100% NEA(teacher union) membership.
