No. Schools may not suspend or expel a student for absences or tardiness. Washington state rules on school discipline have been changing in recent years. The rules used to allow schools to suspend students for skipping school. That is no longer permitted. A student's grades or credits, though, may be impacted by absences if attendance or participation is related to the goals of the class, the teacher has said that attendance will count, and the reasons for the student's absences have been taken into account (including whether the absence or tardiness is directly related to a disability). You can find the rules on discipline at WAC 392-400, online here: http://apps.leg.wa.gov/WAC/default.aspx?cite=392-400&full=true.  Note – sometimes there are changes made to state rules.
