The frustration of eighth graders who are told on the last possible day that they won’t be promoted to high school and participate in advancement ceremonies with their peers may soon end.The Manteca Unified School District board Tuesday is considering a proposal submitted by a committee of elementary administrators and eighth grade teachers and presented to a districtwide gathering of teachers and administrators to clarify requirements and remove “fail safes” that students can use that often mask their overall performance in terms of meeting promotion requirements.The recommendations the board is considering include:uStudents must earn 18 grade points, three grade points for the year, and have an overall grade point average of 1.0 in math, science, social science. English language arts, elective, and physical education in order to participate in 8th grade promotion ceremonies.uAll students will be given a District Math Assessment at the end of each trimester. Each assessment will make up 10 percent of the student’s grade.
