April 22, 2015 -- More than 400 North Shore School District students in grades 3-7 who were scheduled to sit for the Common Core math assessments opted out of the three day exam that began on Wednesday. The Middle School grades had the highest number of opt outs, with just under 50% of 6th graders refusing the exam, and 47% of 7th graders doing so. Overall, a greater percentage, 40.2% of students, refused the Math exam than the English Language Arts exam (38.2%) that was administered last week. The 8th grade, which had the highest opt out rate in the district for the ELA exam, was not scheduled to take the Common Core Math assessment, since those students will, instead, sit for the Algebra Regents exam in June.
