More than a quarter of Stanislaus County students who are learning English as a second language have achieved proficiency in the language, according to test results released by the state Thursday. Yet their schools consider only a fraction of those students fluent enough to keep up with the demands of other academic subjects, a trend seen throughout California. “It’s good that our districts set high standards,” said Chris King, associate superintendent of instructional support services with the county Office of Education. “We know we need to continue to support the kids to help them reach those classification standards and beyond.”
