The Idaho Falls Board of Trustees has finalized the school calendar with Late Start Fridays for the 2021-22 school year. Late Start is part of D91’s efforts to increase student achievement. Late Start gives our teachers valuable time to collaborate and focus on ways to address individual students’ learning needs. While Late Start has historically been on Mondays, Late Start Fridays is working more effectively in most buildings based on feedback from principals and staff. See Final 2021-22 School Calendar.
