Relating to student attendance data; and declaring an emergency.

HB 4154 requires Oregon school districts and public charter schools to collect and report detailed student attendance data starting in the 2026-2027 school year. It defines "chronically absent" as missing 10% or more of school days and "regular attender" as missing fewer than 10%, mandating schools to track these metrics. The data must be disaggregated by student group (including students with disabilities) and made publicly available quarterly on the Department of Education website, with clear explanations of attendance definitions. The law takes effect July 1, 2026, and will apply to all schools reporting attendance data for the first time during the 2026-2027 school year.
