Calling All ThunderRidge Parents!

Here is your chance to see our students at their very best!

Become a Senior Project Judge and celebrate our seniors' learning and accomplishments. This cumulative activity showcases our students’ reading, writing, and speaking skills as well as emphasizes many important “soft skills” such as time management, problem solving, and work ethic. In order for these projects to be successful we are asking for parental and community help with Senior Boards. The Senior Boards listen to and evaluate students presenting their Senior Project.


Underclassmen parents, this is a great opportunity for you to see and understand what your children will be doing their senior year. Senior parents, what better way to support your senior by serving on a board that celebrates their final high school project?


Senior Boards will take place on Friday, April 7th from 9:30 am - 3:00 pm. If you would like to participate on the Senior Boards please click on this link and complete the questionnaire. If you have any further questions, please contact Denise Orsini at [email protected]

Graduation for the Class of 2023 is May 16th at 4:00 p.m. at
University of Denver Magness Arena!

Seniors! Have you completed your 20 hours of community service? Be sure to turn in those forms!
