Read Article LIVERMORE — Directors of Spruce Mountain Regional School Unit 73 on Thursday approved the first reading of policy changes that would allow more students to attend summer school. Changes include lowering the passing grade from 50 to 30 for eligibility, and removing the stipulation that students with 30 or more absences are not eligible. The policy is for students in kindergarten through grade eight. While reviewing the last trimester grades to tally how many of the 350 students at Spruce Mountain Middle School in Jay were failing at least one class, Principal Carolyn Luce got through the first 162 and realized that wasn’t a feasible list.
