Not only are students chronically absent from classes, Flushing teachers claimed, but many students who do attend class don't participate in classwork or complete homework assignments. Students regularly fail tests and other assignments, teachers continued, but still receive passing grades even if they fail the New York State Regents Exams. According to the teachers, the passing rate for their classes last year was around 70%, but only 30% of those students passed the Regents. It's a huge disparity, another teacher said.
