Current Situation

Updated September 27, 2021

At ACDS, we have a battery of COVID-19 precautions in place that have proven incredibly effective in completely curtailing transmission of the virus on campus to date: masks indoors and out, increased ventilation, the ActivePure disinfection system (destroys up to 99.99% of SARS CoV-2 and other airborne pathogens), weekly testing, three-foot distancing (in line with the CDC's recommendation and other research), regular handwashing, dedicated outdoor learning spaces, and more. 

Please review more detail on these measures below. As we continue to navigate shifts in the pandemic threat, we will adjust these measures accordingly. We are committed to providing students and staff a safe, joyful campus environment,  and remain grateful for the school community’s patience, flexibility, kindness and support.

Weekly Testing

Weekly virus testing of all staff and students, at no cost to parents, resumed this year the week before school started; community-wide testing will again be provided following all extended school holiday breaks.

ACDS will follow all CDPH and Santa Clara County protocols for suspected and confirmed COVID-19 cases, including contact tracing and quarantine when necessary.

If a student or staff member is determined to be a close contact, the employee (or the child’s parent) will be notified directly by an administrator. For our parents, if you don't hear from an administrator after a positive case is identified, your child is not required to quarantine.

What can parents do to help?

Parents are asked not to gather on campus at drop-off and pickup. 

Please cooperate with all other school safety efforts: make sure your children have clean masks daily and attend the weekly testing, minimize their exposure to children and adults outside of ACDS. If you travel, please abide by all CDC, state, and county travel guidelines. 

Campus Safety

Coronavirus-rated MERV-13 air filtration in all 43 heating/ventilation systems campus-wide.

High-output portable HEPA air purification units as a third simultaneous system in every classroom to support air quality and added ventilation during smoke days.

Multiple dedicated covered outdoor learning/eating spaces.

Plastic desk shields for teacher use as needed.

Face Masks

The health department orders that face masks are required to be worn indoors by all students, faculty, staff and visitors, regardless of vaccination status. In addition, ACDS requires that all persons on campus wear face masks outdoors as well, except while eating, during certain strenuous exercise in P.E. class, or a brief “mask break” outside authorized by a teacher.


Parents wearing masks, regardless of vaccination status, will be allowed on campus at drop-off and pickup times; parents will not be permitted to enter classrooms. Other non-essential campus visitors will be strictly limited.

Physical Distancing

Although Santa Clara country does not require distancing, ACDS implemented classroom seating configured to provide for three (3) feet of physical distancing in grades K-8; Pre-Kindergarten classes will meet in cohorts.


Students and staff are required to wash hands frequently and use sanitizer, including before and after snack recess and lunch, using multiple washing and sanitizer stations located across the campus.

In 2020, ACDS installed ActivePure air and surface disinfection systems in all classrooms, offices, and bathrooms. ActivePure technology destroys up to 99.99% of all mold, mildew, bacteria, VOCs, and viruses (including SARS CoV-2) in the air and on surfaces, 24/7 at ACDS. Our custodial team also disinfects shared surfaces in classrooms, at workspaces, and in our bathrooms using the Bioesque fogger backpack. 

Touchless faucets have been installed on campus, and our drinking fountains are disabled; we’ve installed water bottle stations on the blacktop and in the Fisher Event Center.
