We can’t wait to see our Wildcats in action!

The end of this school year is fast approaching, and when things get moving this fast, it is good to look back and see how full and rewarding the recent weeks have been. May was testing month, and wow, did it feel long here at Mount Si High School! Between administering 1,695 AP exams, completing SBA testing for 97% of our students and celebrating spring sports state send-offs, all on top of daily life, clubs and all other commitments, our Wildcats were more than ready to welcome June.
But the pace didn’t slow down!
From closing out May with the Senior Car Parade (put together by our always fantastic PTSA!) to starting June off strong with Senior Check-Outs and Senior Awards Night, our 'Cats went straight into the Moving Up Assembly, the Cat Walk and Last Blast, and finally, to top it all off, Senior Prom. All of this to say, the last few weeks have been absolutely packed with memorable moments.
Amid all the excitement, we (with a lot of help) managed to capture a few snapshots of these special days. Enjoy a glimpse into the energy, pride, and celebration that made this time of year so meaningful! And as always, Go, 'Cats!🎉🐾

Today, the Class of 2026 had their final senior class meeting! 🎓
The countdown to graduation is officially on, and the excitement is starting to feel very real. These seniors are entering the home stretch of an unforgettable journey at Mount Si High School. ❤️🖤

Enjoy every moment, seniors!

The 2026 Yearbooks are coming, and we will definitely have a few extras, so if you missed your chance to buy one earlier, your time has come!
Yearbooks will be available to purchase starting on Tuesday, May 26. They will only be available until they're gone, so don't delay! The cost is $65, and you can purchase it at the finance window or online.
Don't forget or miss out again, reserve your copy now!
Please keep in mind that they are not actually here yet, but will be in a couple of weeks, and we'd hate for anyone to miss out on owning a copy of what will certainly be an epic yearbook.

Congrats and best of luck to these Wildcats!
The Boys and Girls Golf teams are heading to the State Championship in DuPont on the 19th and 20th.

Also on the 20th, Boys’ Soccer will compete against the Chiawana Riverhawks in Pasco, in the hopes of clinching the state title once again.

Congrats to all of these hardworking student athletes! Mount Si is cheering you all on! 🐾📣

In honor of Teacher Appreciation Week, we want to give an extra big shout-out of thanks to our incredible teachers. Mount Si High School is home to an amazing group of educators who teach, inspire, support, and care for over 2,000 students every day.
They show up and push through the many expectations, needs, and challenges of ever-changing school life, no matter what each new year brings. We admire and respect their unwavering dedication to their responsibilities and their craft as educators.
Thank you, MSHS teachers, for all you do to be your very best. Wildcats are so lucky to have each of you!
