The Ravenswood City School District, which has about 1,600 students in its elementary and middle schools (excluding charters) in East Palo Alto and Menlo Park, saw chronic absenteeism spike from just 471 out of 2,549 (18.5 percent) during the 2018-19 school year to 846 out of 1,637 students (51.7 percent) in 2021-22. This one district is just one example of a nationwide issue. In 2021-22, 6.5 million more students across the U.S. missed at least 10 percent or more of school days than in 2017-18, according to an Attendance Works analysis. Students miss out on foundation skills that impact them forever when they miss school, including learning to socialize with their peers, said Sara Stone, Ravenswood’s assistant superintendent of teaching and learning.
