John Thomas School of Discovery


  • Due to the change in the school start date and the need to add in additional instructional hours so that students do not have to make-up days, the district has made the following changes to school start times and collaboration time beginning with the 2020-21 school year.


    Bus schedules will be released at a later date as we continue to adjust to the new calendar and times.


    • Collaboration day will now be on Monday morning for ALL schools. This will mean that Mondays will have a late start and school will end at the same time each day (no more early dismissal on Fridays for K-8).
