CAST STEM Principal's Weekly Update

October 31, 2021

CAST STEM families,

Happy Halloween weekend. We hope you have a safe and fun-filled Halloween night.

Congratulations to our College Board National Hispanic Scholars who were recognized at the Legacy Football Game on Thursday night: Alberto Alvarez, Xitlali Hernandez, Karina Jaime-Ramos, Charles Massey, Divanhy Salazar.

Our freshmen enjoyed time with the CAST Network team this week during their first NXU session to explore, articulate and pursue their purpose. Student voice is a central pillar of our foundation at CAST STEM and NXU helps our students to discover their purpose, determine their goals, and connect to their strengths. Thank you to junior CAST Ambassadors who served as mentors during the training: Matthew Friesenhahn, Alexis Martinez, Jennifer Melchor, Ronde Mims.

We look forward to fall pictures and senior pictures with caps/gowns on November 2nd!

Congratulations to our 2021-2022 Teacher of the Year: Ms. Crystal Mares, Junior English Teacher.

Have a great weekend!

In gratitude,

Ravae V. Shaeffer

Proud Principal, CAST STEM HS

Do you need a Verification of Enrollment (VOE) Form for your driver's permit?

VOE is a form that you submit to the DPS when you are applying for a learner's permit or license. It is signed by your school administrator to verify that you are enrolled in school, attending 90% of classes in the semester prior to your application, and that you have been awarded credit for each class you took in the semester prior to applying for your license. If you need to obtain this form, please download and complete the following form and drop it off at CAST STEM. Please be sure to drop it off 24 hours in advance of when you need it. Mrs. Shaeffer will verify your attendance and credits before signing the VOE.
