20/21 School Year. 


Dear Students and Families,

I hope this note finds you and your family safe and healthy.  As some of you have seen or heard Denver Public Schools will be returning in the fall to in-person learning.  As part of DPS’s family of schools Colorado High School Charter plans to return in the fall with in-person learning as well.  This decision was made based on a conglomerate of health departments coming together and making this recommendation that they believe is in the best interest of all students and families.  Based on that recommendation we will have the following precautionary measures in place for the fall:

~ Staff and students will wear masks or other approved face coverings

~ Staff and students will have a health check each day before they enter the school

~ Students will eat lunch and breakfast in newly defined areas

~ Students will work in a cohort model limiting the exposure they have to other students

~ Our buildings will be thoroughly cleaned and disinfected on a daily basis

If a student or family is not comfortable returning to school we will ensure that they have an online option made available to them.  If you or your student is not comfortable returning please reach out to your advocate and we will get you the necessary information.

For those students planning on returning for in-person learning in the fall we look forward to seeing you on August 17th no later than 9:00 am.  If you are new to Colorado High School Charter we look forward to meeting you on August 14th at 9:00 am for new student orientation.   

As all of us know now this virus is hard to predict and while these are our plans at this point in time they may change based on changing conditions and recommendations from our health experts.   

We recognize that these are challenging times and if you need some assistance with food we would love to help. Please reach out to me or your advocate if this is something we can help with. 

Please let us know if you have any suggestions or questions.

Thank you,



Clark P. Callahan


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.
