Current Principal Communiqué

  • December 2019

    Dear Clemens Family,

    I hope you had a restful and enjoyable Thanksgiving holiday. Attached above is this month's campus bulletin and calendar. I hope you enjoy reading about our campus successes and positive learning experiences.

    I would be remiss if I did not boast about the historic seasons both our football and volleyball teams had. The football team captured the district championship! It had been 13 years since the Buffaloes accomplished such a feat. The team also grabbed a bi-district win by defeating Austin Bowie, but fell short to Brandeis in Area play. The volleyball team made history by qualifying for the state tournament. This is only the second time a female team has advanced to state - the last was our girls' basketball team in 1976! We are beyond proud of these student athletes and coaches. We are also grateful for the support of our student athletic trainers, band, cheer, dance, ROTC, choir, and student organizations, along with our amazing parents and community.

    As we approach the end of the first semester, I would like to thank you for your support and ask that you continue to partner with teachers and staff to ensure that your child receives credit for the first half of the year. If you have any questions or concerns, please reach out to your child's counselor or assistant principal.

    Lastly, semester exams will be administered December 17th through December 20th. The schedule is embedded within the attached monthly bulletin. Please note that as per SCUC grading guidelines, any missed semester exam will be recorded as an Incomplete grade and should be made up within a two-week period.

    Thanks again for your continuous support.


    Missy Sosa
    Clemens High School Principal
