Thousands of seniors will graduate at about two dozen high school commencement ceremonies May 30-June 8 around the greater Tri-Cities region.

Most will be at the Toyota Center at 7000 West Grandridge Boulevard in Kennewick and the neighboring Three Rivers Convention Center.

One notable change is coming to Tri-City graduations this year — the Toyota Center has a new clear bag policy in place.

Clear plastic, vinyl or PVC bags no larger than 12-by-6 inches are allowed inside. Smaller clutches that do not exceed 4.5-by-6.5 inches are allowed in.

No weapons or outside food are allowed. Attendees will enter through metal detectors and re-entry is not permitted.

Parking will be limited and no liquids will be allowed into Edgar Brown Stadium, located at 801 North 18th Ave., for Pasco commencement ceremonies. It’s recommended attendees find seating 15 minutes prior to the ceremony, and know which of the two entrances to use.

High school graduations around the Tri-Cities do not require a ticket to attend.

And most ceremonies will be live streamed online.
