Free Student COVID Testing with CCC Partnership
DPS is pleased to announce it is expanding its partnership with COVIDCheck Colorado to offer free COVID-19 testing for students to support a safe return to school. All students and staff will now be able to take a baseline COVID-19 test before coming back to school, and then DPS will be able to offer an ongoing COVID-19 student screening test every other week. As shared with charters through an earlier email from Portfolio, this information will be shared with families through this PSA video, via School Messenger. Thanks to the CDPHE partnership, testing for charter students will be free, and charters will not have to pay for staff testing through March (charges will resume after March). 

Baseline testing can be completed at any of COVIDCheck Colorado’s testing sites via this link (students and staff must use their DPS ID). DPS encourages everyone, unless you have tested positive in the last 90 days, to take a baseline test in the new year. The tests are free, fast, and reliable. See an updated list of testing sites here including at the Montbello campus, Abraham Lincoln Campus, North HS Campus, All City Stadium and a new site at George Washington HS. The test will be completed via nasal PCR test or SalivaDirect™, and results will be returned within 36-72 hours.

At any time, your families and students can schedule a test at existing CCC sites. Any charter student or employee should use the district link, while family members can continue to use the community link.

Good morning,  

I hope this note finds you and your family well during these challenging times.  We thank you for your support and tenacity in helping our students learn in these extraordinary circumstances.  

One of the challenges that we have heard from many of you and our staff is that the uncertainty around how school will look creates added stress.  We want to do everything we can to mitigate additional stress and give our educators, students and families as much time to plan as possible.  So, after looking at the ever-increasing cases in the Denver area we have decided to stay remote through Quarter 3, January 5-March 26.  We will decide about Quarter 4, April 5-May 28, in early to mid-March based on cases and guidance from DPS and the Health Departments.

All our educators are working incredibly hard to provide the most engaging and best online experience for our students.  If your student is having trouble connecting to this material please reach out to their Advocate who can help with technology, hot spots and other resources.   

We recognize these times have brought new challenges and if you and your family need help with food please let your student’s Advocate know. 

Thank you for your support  


Colorado High School Charter Leadership Team


Buenos Dias,  

Esperamos que esta nota los encuentre bien a usted y a su familia durante estos tiempos difíciles. Le agradecemos su apoyo y tenacidad para ayudar a nuestros estudiantes a aprender en estas circunstancias extraordinarias.

Uno de los desafíos que hemos escuchado de muchos de ustedes y de nuestro personal es que la incertidumbre sobre cómo se verá la escuela crea estrés adicional.Queremos hacer todo lo posible para mitigar el estrés adicional y dar a nuestros educadores, estudiantes y familias el mayor tiempo posible para planificar. Entonces, después de observar los casos cada vez mayores en el área de Denver, hemos decidido permanecer alejados hasta el tercer trimestre, del 5 de Enero al 26 de Marzo. Decidiremos sobre el cuarto trimestre, del 5 de Abril al 28 de Mayo, de principios a mediados de Marzo, según los casos y la orientación del DPS y los departamentos de salud.

Todos nuestros educadores están trabajando arduamente para brindar la mejor y más atractiva experiencia en línea para nuestros estudiantes. Si su estudiante tiene problemas para conectarse a este material, comuníquese con su Representante Estudiantil, quien puede ayudarlo con tecnología, puntos de acceso y otros recursos.

Reconocemos que estos tiempos han traído nuevos desafíos y si usted y su familia necesitan ayuda con la comida, informe al Representante Estudiantil de su estudiante.


Gracias por tu apoyo,

El Liderato de Colorado High School Charter

Joint Statement from the Board and Executive Director, Clark Callahan. 
Like many others following the death of George Floyd, CHSC is angered, disturbed and broken hearted. Our country has waited far too long to recognize and eliminate the racism that has plagued our nation since its founding. As an organization, we are committed to the work of eradicating racism, seeking justices and empowering all people. Now, more than ever, we will dedicate our assets, time and energy to this important work and to the continued education of the many diverse communities we serve. 
Greg Mestas, Cyndi Bush-Luna, Michael McArthur, Nneka McPhee, Nick Bucy, Stella Yu, Phyllis Kadison and Clark Callahan. 
Mensaje de parte de el Director Ejecutivo y Junta Directiva. 
Como muchos otros después de la muerte de George Floyd, CHSC está enojado, perturbado y con el corazón roto. Nuestro país ha esperado demasiado tiempo para reconocer y eliminar el racismo que ha afectado a nuestra nación desde su fundación. Como organización, estamos comprometidos con el trabajo de erradicar el racismo, buscar justicia y empoderar a todas las personas. Ahora, más que nunca, dedicaremos nuestros activos, tiempo y energía a este importante trabajo y a la educación continua de las diversas comunidades a las que servimos.
Greg Mestas, Cyndi Bush-Luna, Michael McArthur, Nneka McPhee, Nick Bucy, Stella Yu, Phyllis Kadison and Clark Callahan.
