2026 WEB Day | ALL Incoming 6th Grade Students

 

All incoming 6th graders are invited to attend WEB Day on Wednesday, August 5th, at 8:30 am. WEB, which stands for Where Everybody Belongs, is a national program that provides 6th graders with guidance and support through the initial year of their middle school experience.

WEB Day is designed to foster a sense of comfort, belonging, and readiness for the OIS experience. The program features small- and large-group interactions, tips for success, and a special campus tour. Beyond the initial days of school, our WEB leaders provide a variety of follow-up activities and social events to support our sixth graders and build relationships throughout the school year. We look forward to meeting and greeting your child Where Everybody's a Bulldog!

 

Can’t make it to WEB Day? Don’t worry! 

 

We will host an “in case you missed it” WEB Day on Monday, August 10th, from 3:30-5:30 pm at OIS.

 

Since we will offer a make-up WEB Day, we are asking our incoming 6th-grade families to RSVP for which event they will be attending so that we can plan accordingly. Please fill out this WEB Day RSVP here by August 1st.
