Upper Arlington Schools to transition to full-day kindergarten for 2021-22 school year The Upper Arlington class of 2034 will be historic in at least one way. Kindergarten students entering Upper Arlington Schools in the fall will be the first to attend full-day classes, five days a week. Due to a transition the district rolled out as part of its facilities master plan, completed in May 2017, it will move to full-day kindergarten classes for the 2021-22 school year. It will be a departure from the current half-day system, in which students attend a morning session from 8:15-11:05 a.m. or an afternoon session from 12:05-2:50 p.m. Both sessions are Monday through Friday.
