Communique 5 April 14th, 2026

We really appreciate everyone's understanding and patience as we worked through the various last-minute changes taking place on campus. A special shoutout to Will Mason from Polytechnic and the Caltech team for going above and beyond to ensure a successful tournament. A few items to close out this year's State Tournament.

The Division B and Division C final scores for the 2026 Southern California State Science Olympiad are posted. There were no changes to the preliminary scoreboard. Congratulations to Sierra Vista Middle School and Troy High School, who will represent SoCal at the upcoming National Tournament!

To help us improve the State Tournament, please fill out our feedback form and ask your students to do so as well.

Pictures from the awards ceremony are available here.

For seniors interested in volunteering next year, please email our Event Supervisor Coordinator, Stanley Suen. They do not have to be a local college next year - we can connect them to tournament officials in other states too.

The Certificate of Excellence and Appreciation were sent to the coaches for their use.

More information about the upcoming National Tournament and how you can be involved and summer workshops will be coming!

Thank you again for all that you do for the students and the program, and we look forward to seeing you at the local tournaments next year!

Communique 4 April 11th, 2026

The preliminary Div B and Div C results for the 2026 Southern California State Science Olympiad Tournament are posted on Duosmium and they are subject to review. Head coaches have until Monday, April 14th at 5:00 pm to submit any questions/concerns or issues regarding the Preliminary Scores. As a reminder, this period is only for tabulation questions (e.g. your team received a no-show when your team was there). The scores will be considered finalized when they are posted on the State website following this review period.

Communique 3 April 10th, 2026

Thank you so much everyone for your patience as we figure out last minute campus updates. Currently, it appears that the weather will hold

Home Bases:
Home bases have been assigned and can be viewed in the tournament map Zoom in around Gates buildilng to see the home bases.

Room Changes:
- Rocks and Minerals B/C is now in Resnick 120
- Boomilever B/C is in Avery fireplace
These changes are reflected on v4 of the here.

Communique 2 April 9th, 2026

As we approach the State Tournament, the current forecast has a slight chance of rain on Saturday. Please note that Science Olympiad is a rain or shine event and the tournament will continue as long as it is safe to do so.

Below are a few reminders:
- Do not park or arrive on campus until 7:00 AM. The Fire Marshal will be there, and the permit for the event does not start until 7:00 AM.
- Please remind team members and guests to stay near the base camp. It is okay to enjoy the campus outdoors, but please do not wander around within buildings as research is taking place even on weekends. Because we are borrowing shared building spaces, please keep noise levels to a minimum to be respectful to those working and carrying out research in the other parts of the building.
- Food and drinks are not allowed inside academic buildings. Food will be available for sale in Browne Dining Hall throughout the event.
- Do not photograph or take videos of devices of another team without their permission.
- Review the Code of Conduct and Media Recommendation

Final Schedule
The final schedule have been posted in the download section below. As we update the schedule, the one posted on the web page and the digital map will also be updated.

Helicopter B/C Venue Dimensions:
Helicopter B/C will take place in Braun Athletic Center Squash Courts. The space is 6.40 m in width, 9.70 m in length, and 6.10 m in height.
Additionally, you can optionally sign up for updates from Caltech Athletics. They will email you with recruitment opportunities, and to thank you for your participation in the 2026 SoCal State Science Olympiad tournament.

Engineering CAD C:
Coaches were sent a form for their participants in Engineering CAD to fill out before their competition time. This is to ensure that on the tournament day, Event Supervisors do not have to ask participants for them during the time block, delaying the event start.

Code Craze B/C:
Please remind your Code Craze participants to bring a laptop per team. We recommend the Code Craze Participants go through the courses for Middle School and High School to become familiar with the CodeHS platform and some of the content that can be covered on the exam. To save time, it would be appreciated if participants could connect to the Caltech Visitor WiFi network before the Code Craze event.

Caltech Robotics Club
The Caltech Robotics club will be doing demos of their robots from 3pm-5pm right outside of the Gates-Annex building. This will be a great opportunity to learn more about robotics and talk to Caltech undergraduate students.

Restrooms:
Please note that restrooms are available in most buildings that we are using for the tournament, and are shown on the Tournament Map. From the home bases, the closest restrooms to Caltech Pond are in Bridge. From Bechtel Mall, the closest restrooms are in Kerckhoff.

Keeping the Campus Clean:
Please be courteous and help pick up any trash in your area as a way of thanking the school for their hospitality and help in hosting the tournament. The goal is to keep the grounds free of any debris and trash and restore it to its pre-event condition before our arrival. Thanks for your help and support in making this possible.

Parent Volunteer Assignments
The parent volunteer assignments are now posted. Teams must have 1 adult volunteer present for the entire duration listed for the given event. Coaches can either ask 1 parent volunteer to complete it or 2 parent volunteers to split up the 2 hours. Please make sure to let your parent volunteers know when and where they need to be on the day of the event. There are no cards or papers to sign. Parent Volunteers should report directly to the assignment (not check-in table), they need to let the event supervisor(s) know which school they are representing and that they are a parent volunteer. Please make sure that the adult volunteer(s) do not have any conflicts of interest with their role (e.g. coaching a team in the division they are volunteering with, or having relatives competing in the division they are volunteering with). If you have any questions regarding your assignment, please let us know

Tournament Map
The tournament map is now available. We have marked the location of each building/event on the map. Please share this with your participants and guests to help them navigate the campus. Although the information in the app has been reviewed and updated to match the Preliminary Schedule, rooms and venues are subject to change.
Zooming in will show the approximate location of the room within the building.
Clicking on rooms/buildings will show when and what events are taking place.
Clicking on rooms will also show what floor the room is on.
There are rooms in basements; "B1xx" identifies rooms in the first basement level, "B2xx" identifies rooms in the sub-basement (2 levels down from ground level).

Team Home Bases
Team home base locations are currently being finalized. We'll provide an update very soon.

Caltech Admissions Info Session & Campus Tours:
Caltech Admissions will hold an informational Q&A session for students, parents, and coaches at 10 AM in Chen 100 Auditorium. Due to limited seating, only the first 150 guests will be allowed.

Lab Tours:
Thank you to all who submitted requests for lab tours. Due to high demand we were not able to accommodate tours for all teams, so we prioritized teams that did not participate in a lab tour last year. Please refer to this sheet for assignments.
For those teams that will be touring a lab, please have your team meet directly in front of Beckman Auditorium at 3:45pm or 4:45pm based on your assigned slot. Please remember that all students on the tour must be one of the official team members with a wristband (a competitor or alternate). Additionally, your team must provide one adult chaperone who will accompany the team on the tours. Note that due to the size of many labs, we cannot accommodate more than one chaperone.

[Updated] Awards Ceremony:
The Awards Ceremony will be held in the Gamble Gym at Polytechnic School and will be divided by division: Division B from 5:30-6:30 PM and Division C from 6:30-7:30 PM. Doors will open at 4:45 PM for the Division B awards. While wristbands are not required for the ceremony, we kindly ask that Division C team members, their friends, and families wait until the Division B awards have concluded before entering the gym.

Awards Livestream:
Unfortunately, there will be no livestream this year.

Preliminary and Finalized Scores:
Preliminary scores will be posted for review on the State website by the end of Saturday, April 11th and they are subject to review. Head coaches have until Monday, April 13th at 5:00 pm to submit any questions, concerns, or issues regarding the Preliminary Scores to peterhung@socalscioly.org.

This is how we will confirm that you are receiving our emails and updates and are planning to attend the upcoming program. You can also add the contact information for one co-coach and one team email, so we have more than one way to contact your team in case you will be on break. Please note that you do not need to submit the names of students, alternates, or parent volunteers during the registration at this time, so please register. Only the first submission will be accepted, so please coordinate with any co-coaches.

Spring Break Recess:
We understand that many of you will be on Spring Break in the upcoming weeks. Please note that any updates will be sent to both your email address and posted online. Please ask your students to check this web page during their Spring Break, especially if you will not be able to relay relevant information to the team. You can also add the contact information for one co-coach and one team email in the online registration form.

Certificate of Liability Coverage (Urgent and Time Sensitive Follow-Up):
The Southern California Science Olympiad, the California Institute of Technology (1200 E. California Blvd., Pasadena, CA 91125), and the Polytechnic School (1030 E California Blvd, Pasadena, CA 91106) require that your school/district provide us with a "Certificate of Liability Insurance" or "Evidence of Coverage" Certificate to attend and participate in the April 11th, 2026 SoCal State Science Olympiad program being held on the campuses of the California Institute of Technology and the Polytechnic School in Pasadena, CA.

Schedule and Team Numbers:
An updated preliminary schedule and team numbers have been posted in the download section below While we do not expect any major changes to the schedule at this point, we will let you know if there are any updates to the schedule. As we update the schedule, the one posted on this web page will also be updated.

Trial Event:
We will be running Code Craze B/C as Trial Event this year. The rules for these events are in the rules manual. The trial event do not count toward the team total but medals will be awarded. Any students from your school, including but not limited to the 15 official members, may participate in these events. These students will not receive wristbands but they must fill out all the forms as required for the 15-member teams as well as be listed on the team roster.

15 Official Team Members Roster Requirement:
The head coach of the team should bring and submit a final official roster of participating students (15-member team and students participating in the Trial Event) on the day of the tournament during the morning check-in time. The head coach needs to also submit the release forms for the students. If there is a change in the composition of the team, this is simply recorded on the roster that you bring on the day of the event.

Wristbands will be provided for your team members upon check-in. You will receive up to fifteen (15) wristbands for the official members of the team depending on the size of your team. Please be aware that there is no maximum or minimum number of events that any student must compete in at the State Tournament. We are aware that teams may employ an organizational system that includes maximum or minimum numbers to manage the team and schedule, but that is not a requirement of the State Science Olympiad program. Please make sure you check the National Science Olympiad guidelines at on who can be on your 15-member team.

As a reminder, there can be a maximum of seven 12th graders on a Div C team and five 9th graders on a Div B team. This applies only to the official 15-member team. Those participating in the trial event do not have to follow the maximum 12th/9th grader limit as the scores for the trial event do not impact team ranking.

We do not expect schools to substitute team members during the tournament. However, if an emergency should arise and a student on your team is unable to compete, you should discuss that situation with a Tournament Coordinator on the day of the event.

No Practicing at Polytechnic or Caltech:
Please remind your parents and teams that practicing your devices on Polytechnic Campus and Caltech Campus is strictly prohibited prior to the tournament. Teams should arrive no earlier than 7 AM on Saturday. We are grateful that Caltech and Polytechnic are willing to host the State Tournament and that they have committed to sharing their staff and selected facilities on Saturday, April 11th. Research and classes are still ongoing and it is not acceptable to come onto campus to practice in the gyms or other facilities. Please do not jeopardize the possibility of having Caltech and Polytechnic host this and other Science Olympiad events in the future.

Online Sign-Up for Self-Scheduled Events:
We will be using the Event Sign-Up System (ESUS), for the self-scheduled event sign-ups. Login information will be emailed to the head coaches of each team by noon Wed, April 1st. If you do not receive the username and password by Wed, April 1st 5pm, please contact us immediately because the self-scheduled event online sign-up will open on Thurs, April 2nd at 5:00 PM, and will close on Tues, April 7th at 5:00 PM. For technical issues, please contact esus@socalscioly.org.

Parent Volunteer Assignments:
Similar to last year, we are asking each team to provide an adult volunteer to help with tasks on tournament day. Each team must provide about 3 people- hours of support. The assignments will not require technical knowledge of the events and may include: making sure the doors are shut for the flight events, helping with delivering lunches, checking in students, helping at the registration table, etc. Most assignments can be performed by just 1 adult volunteer for 3 hours. Please make sure that the adult volunteer(s) do not have any conflicts of interest with their role (e.g. coaching a team in the division they are volunteering with, or having relatives competing in the division they are volunteering with). The assignment will be posted after teams have accepted their bids.
