Welcome to MESA! We will post updates here periodically throughout the year. 

It's never too early to start thinking about MESA Day! MESA Day will be on February 28, 2026 this year.
Final Rules for 2025-26 will not be up until around November, but the projects should remain relatively the same. 
Check out this flyer for a summary of the projects: MESA Project Flyer

Students! You can start sending in your MESA Day 2026 T-Shirt Designs!

Our yearly MESA Day t-shirt is design by you, the students! We are accepting submissions now until December 5th. Please see flyer for more details. 

Pacific MESA STEAM Day - October 25, 2025 - 9am-12pm

Replacing our Fall Scavenger Hunt, Pacific MESA is hosting our first STEAM Day where our MESA schools will host STEAM activity tables.  Pacific School of Engineering student organizations will also host game tables and provide information about their groups. 

Guests will receive a bingo card stamp for every activity they do and after they complete a certain number of activities they can redeem their bingo card for a Kona Ice snow cone voucher. 

If guests RSVP for the event, they can get a MESA sticker at registration! 

If you are a MESA Student interested in hosting an activity table for your school, let your MESA advisor know so they can add you to the list! Up to 5 students can host an activity table from each school and guests can vote for their favorite table. The top 3 voted tables will be invited to a Pacific MESA game night at our gaming center!

MESA Day is on February 28, 2026!
​
Stay tuned for updated informational videos about the MESA Day

DRAFT RULES SHOULD BE UP IN SEPTEMBER. STAY TUNED!
Please note that we will NOT be hosting Crime Scene and Bio Breakthrough this year but they should be returning next year.
