April 13, 2016 -- More than 400 North Shore 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, said school district officials. The Middle School grades had the highest number of opt outs, with just under 60% of 7th graders refusing the exam, but a significantly lower 37% of 6th graders doing so. Overall, nearly the same percentage, 41.6% of students, refused the Math exam as did the English Language Arts exam (42.5%) that was administered last week. The 8th grade, which had the highest opt out rate in the district for the ELA exam (54.4%), was not scheduled to take the Common Core Math assessment, since those students will, instead, sit for the Algebra Regents exam in June.
