It's a year of transition for many Salem-Keizer: Four schools are navigating around construction and campus expansions, and many have new principals.

At Judson Middle School, cafeteria expansions have students temporarily eating lunch in the school gym. Staff set up and put away tables daily, leaving the gym open for about half the school day.

Some changes are already visible on campus. A new secure entryway installed during the summer means staff can control who enters the building.

At Sprague, former assistant principal Chad Barkes took the helm this year. The first day was crowded at lunch — he said it usually takes freshman a few days to realize they can take their food outside and don't have to cram together at lunchroom tables.
