COVID-19: K-12 Schools

Students in School Raising Hands Wearing Masks YSTSSchool district leaders across the state have been consulting with their local and tribal health departments and making difficult decisions as they balance the need for virus mitigation measures with quality instruction, access to technology and internet, and the challenge of connecting students and families with needed resources like food, special education services, mental health services.

The guidance and resources on this page will help decision-makers plan, prepare, and respond to the COVID-19 pandemic.



Guidance and resources

Our recommendations will be updated as the COVID-19 pandemic continues to evolve. The Centers for Disease Control and Prevention (CDC) has additional information for school and program administrators in K-12 and higher learning settings.

 K-12 Outbreak Guidance

Guidelines for the Prevention, Investigation, and Control of COVID-19 Outbreaks in K-12 Schools in Wisconsin will help local and tribal health departments as they work with school administrators to help prevent and control outbreaks, and make decisions about implementing layered prevention strategies in K-12 schools. 

On February 3, 2022, DHS updated this guidance to align with recommendations from the CDC. See a summary of key takeaways and updates.

 Testing Support for Wisconsin Schools

To assist public and private schools in operating safely, DHS has received federal funding to develop a program to support school-based COVID-19 testing for teachers, staff, students, and their families. More information on the program can be found on the COVID-19: K-12 School Testing Program webpage.

 Guidance for Hosting an On-Site Vaccination Clinic

Schools who want to hold an on-site vaccination clinic for eligible students, staff, and families can communicate their interest to DHS by filling out the vaccination clinic matching survey and learn more on the COVID-19: Vaccine Partner Resources webpage.

 Guidance for Sport Youth Programs

For high-risk sports and activities in areas with low and moderate COVID-19 transmission, DHS recommends screening testing at least once per week. For high-risk sports and activities in areas with substantial COVID-19 transmission, DHS recommends screening testing twice per week. DHS recommends canceling high risk sports and activities in areas with high COVID-19 transmission. 

Low and intermediate risk sports and activities do not need screening testing in areas with low transmission but screening testing should occur at least once per week if there is moderate, substantial, or high transmission levels. 

Examples of low-risk sports are diving and golf; intermediate-risk sport examples are baseball and cross country; high-risk sport examples are football and wrestling. High-risk extracurricular activities are those in which increased exhalation occurs, such as activities that involve singing, shouting, band, or exercise, especially when conducted indoors.

For additional guidance, see the CDC website

 Recommendations for Graduation Ceremonies

DHS recommends that people avoid large events and gatherings, including traditional graduation ceremonies. If a school decides to hold an in-person graduation ceremony, they should hold it outdoors , limit attendance to allow participants and attendees from different households to stay at least 6 feet apart, require masks, , and ensure that their events comply with all applicable local public health orders. Individuals should consider getting tested for COVID-19 before attending any type of gathering with others outside of their household. Self-tests can be taken at home, are easy to use, and produce rapid results. 


Schools that choose to hold graduation ceremonies can follow CDC’s recommended phased mitigation strategies (see bottom of Table 2) for extracurricular activities to help inform safety measures based on their local level of community transmission. Schools holding graduation ceremonies should also follow CDC’s Guidance for Organizing Large Events and Gatherings.

  • Some ideas to mitigate the risk of in-person graduation ceremonies include:
  • Holding ceremonies outdoors in a space large enough to allow for physical distancing of 6 feet or more between members of different households.
  • Limit the number of attendees for each graduate.
  • Requiring well-fitting masks for all participants and in-person attendees.
  • For indoor ceremonies, making sure ventilation systems are operating properly and increase the circulation of outdoor air as much as possible.
  • Ensuring that there are adequate supplies to support healthy hygiene, such as soap, water, hand sanitizer containing at least 60% alcohol, paper towels, and no-touch trash cans.
  • Limit the number of people who occupy public spaces at one time to allow for physical distancing.
  • Ensuring that people standing in line can maintain 6-feet of distance between one another. It may be helpful to post signs or markers to help attendees maintain the appropriate physical distance.
  • Encouraging guests to avoid singing or shouting, especially indoors. If possible, keep music levels down so people do not have to shout or speak loudly to be heard.

Some ideas to honor seniors through virtual or other alternative celebrations include:

  • Holding a virtual graduation ceremony and mailing diplomas to graduates.
  • Asking seniors to send individual videos with short messages to their graduating classmates. This, with the traditional filmed speeches by invited speakers, creates a longer film highlighting the graduates’ high school experiences and provides a long-term memento.
  • Highlighting seniors on social media each day with special hashtags that allow for family, friends, and community members to congratulate individual students (who agree to participate) with photos and messages.
  • Using main street windows to display pictures of individual students (who agree to participate).
  • Securing a digital billboard and displaying messages directly from graduates to their class. Consider expanding to include messages from families and friends to graduates as well.
  • Individualized ceremonies: School leaders could visit each graduate’s home, while remaining outside and at least 6 feet away, to congratulate and take photos of each graduate in their cap and gown and holding their diploma. This type of recognition may need to be conducted over the course of several days depending on the class size.
  • Drive-through ceremonies, with families in separate vehicles. 

As school districts plan for alternatives to traditional graduation ceremonies, they should coordinate with local public health departments, local law enforcement, legal counsel, families, and other community members to ensure that any graduation celebration meets all expectations and requirements for physical distancing or other public health protections.

Frequently asked questions

Why should kids in schools be wearing masks, even if they are up to date with their vaccines? 

Children who are up to date with their vaccines should continue to wear well-fitting masks in schools due to the highly transmissible nature of SARS-Cov-2 and because K-12 schools are settings with high mixing of vaccinated and unvaccinated people Mask use is particularly important when physical distancing or other prevention strategies cannot be maintained. In accordance with CDC guidance, DHS recommends schools require universal masking for all teachers, staff, students, and visitors, regardless of vaccination status. It is recommended that individuals wear the most protective mask or respirator they can that fits well and that they can wear comfortably for long periods of time. Children should continue full-time in-person learning with layered prevention strategies in place.

What is the latest guidance on physical distancing in school settings?

DHS recommends that schools maintain a minimum of at least 3 feet of physical distance between students in classrooms, combined with indoor mask wearing for all, regardless of vaccination status, and other layered prevention strategies. Teachers and adult school staff still should maintain at least 6 feet of physical distance with students and with each other, to the greatest extent possible.

In K-12 classroom settings only, students who were within 3-6 feet of an infected student are not considered close contacts if both students were correctly and consistently wearing a well-fitted mask. For teachers and adult staff, the distance used to define a close contact remains at 6 feet.

Students and staff should maximize physical distance as much as possible when masks cannot be worn, such as when eating (especially indoors). Schools should not exclude students from in person learning to keep a minimum distance requirement. When it is not possible to maintain a physical distance of at least 3 feet, schools should layer as many other prevention strategies, including universal masking, as possible.

For more information, see Guidance for COVID-19 Prevention in K-12 Schools.

What is considered a COVID-19 outbreak in a school?

A suspected outbreak of COVID-19 in a school is defined as the presence of at least two confirmed or probable cases of COVID-19 in the same school building, with onset dates within 14 days of each other. 

Both suspected and confirmed outbreaks of COVID-19 in a school must be reported to the local or tribal health department as soon as they are confirmed.

If two or more confirmed or probable cases of COVID-19 are identified in the facility with onset dates within 14 days of each other, and the public health investigation identifies an epidemiologic link between the illnesses and the school (for example, close contact occurred at school, multiple illnesses in the same room, shared staff member among cases), the outbreak is then a confirmed COVID19 outbreak associated with the school. 

On January 21, 2022, DHS issued memo BCD 2022-01, informing public health and health care partners that contact tracing is no longer expected or required for every COVID-19 case. Depending on the facility type and staffing resources, local and tribal health departments may choose to lead case investigation and contact tracing efforts during outbreaks, or to educate and train facility staff to assist with the management of the outbreak. In coordination with the school, public health staff should investigate suspected and confirmed outbreaks to determine if the illnesses are related, how they may have been acquired, and if they are part of a larger outbreak. Specific infection control measures should be implemented at a facility where an outbreak occurs to prevent further transmission and keep children and staff safe. The following sections provide an overview of those outbreak prevention and control measures. 

Parents, teachers and staff, school-based health care providers, and LTHDs all play a role in detecting cases of COVID-19 and identifying close contacts of cases in the school setting. Those roles are outlined in the Guidelines for Prevention, Investigation and Control of COVID-19 Outbreaks in K-12 Schools in Wisconsin.

How are outbreaks in schools investigated? 

The roles and responsibilities for conducting contact tracing in schools may be assigned by LTHD jurisdiction or school district. However, any approach should include input from both school district administration and LTHD staff. Depending on staffing resources, LTHDs may choose to lead case investigation and contact tracing efforts during outbreaks, or to educate and train facility staff to assist with the management of the outbreak.

Information on how an outbreak investigation is conducted can also be found in the Guidelines for Prevention, Investigation and Control of COVID-19 Outbreaks in K-12 Schools in Wisconsin. The primary goal of an outbreak investigation is to ensure close contacts are identified as quickly as possible so they can take proper precautions (quarantining and testing) to minimize further spread of the outbreak.

What are the exclusion criteria in schools and child care settings when someone experiences symptoms post-COVID vaccination?

Systemic signs and symptoms, such as fever, fatigue, headache, chills, muscle aches and pain, and joint pain, can occur following COVID-19 vaccination. Preliminary data from mRNA COVID-19 vaccine trials indicate that most systemic post-vaccination signs and symptoms:

  • Are mild to moderate in severity.
  • Occur within the first three days of vaccination (the day of vaccination and the following two days, with most occurring the day after vaccination).
  • Resolve within 1-2 days of onset.
  • Are more common and severe following the second dose, and among younger persons compared to those who are older (>55 years).

Cough, shortness of breath, runny nose, sore throat, or loss of taste or smell are not consistent with post-vaccination symptoms, and instead may be symptoms of SARS-CoV-2 or another infection.

The following chart should be followed for exclusion criteria when someone starts to experience symptoms within three days (the day of vaccination and following two days) of receiving either dose of the COVID-19 vaccine.

Signs and symptoms
Suggested approach
Signs and symptoms unlikely to be from COVID-19 vaccination:
  • Cough
  • Shortness of breath
  • Runny nose
  • Sore throat
  • Loss of taste or smell

Follow exclusion criteria in the Guidelines for the Prevention, Investigation, and Control of COVID-19 Outbreaks in Child Care Settings and Guidelines for the Prevention, Investigation, and Control of COVID-19 Outbreaks in K-12 Schools in Wisconsin.

If performed, a negative SARS-CoV-2 antigen test in a staff member who has signs and symptoms that are not typical for post-vaccination should be confirmed by a SARS-CoV-2 nucleic acid amplification test (NAAT), such as RT-PCR or LAMP.

Signs and symptoms that may be from either COVID-19 vaccination, SARS-CoV-2 infection, or another infection (for example, influenza):
  • Fever
  • Fatigue
  • Headache
  • Chills
  • Muscle aches/pain
  • Joint pain

Recommend evaluation by health care provider.

Staff who meet the following criteria may be considered for return to work without viral testing for SARS-CoV-2:

  • Feel well enough and are willing to work.
  • Are afebrile.*
  • Systemic signs and symptoms are limited only to those listed to the left (i.e., do not have other signs and symptoms of COVID-19 including cough, shortness of breath, sore throat, or change in smell or taste.

If symptomatic staff return to work and symptoms are not improving or if symptoms persist for more than two days, they should be excluded from work pending further evaluation from a healthcare provider. If feasible, recommend viral testing.

If diagnosed with another illness, refer to your district's return to work policy.

*Staff with fever should be excluded from work pending further evaluation, including consideration for SARS-CoV-2 testing. If an infectious etiology is not suspected or confirmed as the source of their fever, they may return to work when they feel well enough.


Do students and staff who are up to date on their vaccines need to follow the exclusion guidance in the Guidelines for the Prevention, Investigation, and Control of COVID-19 Outbreaks in K-12 Schools in Wisconsin if they develop symptoms?

Yes, symptomatic students and staff who are up to date on their vaccines should follow the exclusion criteria in the Guidelines for the Prevention, Investigation, and Control of COVID-19 Outbreaks in K-12 Schools in Wisconsin. It is possible for individuals who are up to date on their vaccines to experience mild COVID-19 infections.

If someone is up to date on their vaccines and is exposed to COVID-19 they should be tested at least 5 days after exposure and wear a mask in public indoor settings for 10 days starting with the date of last contact with the infected person or until they receive a negative test result. Close contacts who are not up to date with their vaccines will need to quarantine for a 5-day period starting with the date of last contact with the infected person and should be tested at least 5 days (or 5 to 7 days) after exposure. They should wear a well-fitting mask for an additional 5 days after being released from quarantine. Any child or staff member who experiences COVID-19 symptoms should get a COVID-19 test, stay home, and complete a minimum 5-day isolation period.

Are teachers and other school staff required to follow quarantine and isolation protocols?

Although DHS has acknowledged that there may be circumstances wherein certain workers would need to be exempted from quarantine protocols, DHS limited these exemptions to health care workers and other situations where quarantine could impact “public health and safety.” This means that school administrators, teachers, and other staff should continue to follow the quarantine and isolation protocols in the school outbreak guidance released by DHS.

An unvaccinated student or faculty/staff member previously had a positive COVID-19 antibody test. Should quarantine be recommended if they have close contact with someone with COVID-19?

Yes, if the student or faculty/staff member is not up to date with their vaccines, they should stay home and quarantine.  An antibody test should not be used to determine the need for quarantine following close contact with someone who has COVID-19.

Wisconsin Department of Public Instruction

Keeping all educators, staff, and students in school buildings safe and healthy is a top priority. The Wisconsin Department of Public Instruction (DPI) has provided critical information on policy, practice, and messaging for school districts to use while navigating the many factors necessary to carry out safe in-person learning. View DPI's COVID-19 Infection Control and Mitigation Measures for Schools 2021-2022. (PDF)

Find information for child care providers

Preventing and controlling COVID-19 in child care settings poses unique challenges due to the nature of caring for infants and young children, which necessarily involves close contact between children and their caregivers.
