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.

There are TWO key websites you will need to access as an OIS parent: Aeries and Membership Toolkit (MTK).

Aeries is where you will access and interact with the Orinda Unified School District, including registering for school, updating emergency contact and health information, and accessing report cards and standardized test scores.
If you’re new to the school district, you’ll need to create an account on this Parent Club website (MTK). If you’re a returning OIS family or are moving up from an OUSD elementary school, you should already have an account. You just need to log in to update your information and preferences (log in with your normal MTK email account).

Please complete the steps below to ensure you have full access this academic year. If you have any issues, please email OIS Parents' Club.
