Back Bay Principal Deborah Davis said the school uses a specific teaching model to ensure students pass.
"I was thrilled and pleased and not totally surprised," Davis said. "Our district is focused on helping kids through the CAHSEE. That includes looking at their history. The district provides tutorial instruction in English and math. We look at their past test results, and select areas were they need a little more success. It's a very scripted teaching style."
