CCSD21 Together

SHIELD Illinois weekly COVID testing

CCSD21 has partnered with SHIELD Illinois (University of Illinois) to administer weekly saliva PCR tests to in-person students and staff beginning districtwide Tuesday, March 16. This is a non-invasive saliva test and there is no cost to families or staff for testing. Results will be available to School District 21 within 24 hours of testing and will be shared with the student’s parent/guardian by email shortly thereafter. More information about SHIELD Illinois testing is available here:

Additionally, a virtual parent information night about SHIELD testing was held Monday, March 8, at 7:00 PM. The evening began with a livestream replay of the Deerfield 109 SHIELD Testing Town Hall (linked above).

The implementation of a comprehensive testing program is an important part of our effort to increase the amount of in-person learning time. For this reason, testing for in-person students will be considered mandatory unless there is a specific and valid reason that a child should be exempted. Any parent or guardian seeking an exemption to mandatory testing should contact their school principal.


Tests positive for COVID-19 (exclusion) Everyone, regardless of vaccination status, must do the following:

  • Stay home for a minimum of five days and a maximum of 10 days after the first day of symptoms or the specimen collection date from positive viral test for asymptomatic persons.
  • Continue to wear a mask around others for five more days after returning to school.

Individuals may return to school after five days if asymptomatic or if fever-free without fever reducing medication for 24 hours, diarrhea/vomiting have ceased for 24 hours, and other symptoms have improved. 

Be aware that your clinical provider may determine that you need a longer period of isolation based on certain underlying clinical conditions such as a weakened immune system. 

Have COVID-19-like symptoms 


Everyone, regardless of vaccination status, must immediately be excluded from school until: 

  • Receiving a negative test result that confirms the symptoms are not attributable to COVID-19; or
  • For a minimum of five days and a maximum of 10 days until fever free without fever reducing medication for 24 hours, diarrhea/vomiting have ceased for 24 hours, and other symptoms have improved.

Those testing positive should be excluded from school and follow guidance for persons testing positive. 

If displaying COVID-19 like symptoms, students and staff are required to stay home while awaiting the results of a test.  

Exposed to someone with COVID-19 and have no COVID-19-like symptoms (exclusion) The following people are close contacts* who must be excluded from school: 

  • Students and staff who are not fully vaccinated (completed primary series).
  • Students and staff aged 18 years and older who have received primary COVID-19 vaccine doses but have not received a booster dose when eligible (“unboosted”).

As an alternative to exclusion for individuals who are close contacts, schools may permit close contacts without symptoms of COVID-19 who were exposed in the school setting during the school day (excludes extracurricular activities) to remain in school through Test to Stay. 

Individuals without symptoms of COVID-19 who are not participating in Test to Stay: 

  • Must stay home for five days after the last contact with the person who has COVID-19;
  • Must wear a mask around others for five additional days and remain asymptomatic; and 
  • Should test for COVID-19 on day five. Those testing positive should be excluded from school and follow guidance for persons testing positive.

Data and metrics

The district will continue to monitor multiple sources of COVID-19 infection data and will implement adaptive pauses to in-person instruction at the classroom, school, or district level as conditions require.

Sources include data from the Cook County Department of Public Health and the Illinois Department of Public Health, as well as the COVID-19 Dashboard maintained by the Northwestern Medicine’s Surgical Outcomes and Quality Improvement Center. In addition we are tracking our internal data on the CCSD21 COVID-19 Data Dashboard.

Mitigation of spread

Per joint guidance from the Illinois State Board of Education and Illinois Department of Public Health, as well as guidance from the Centers for Disease Control (CDC), the minimum distance in effect in classrooms is 3 feet. A minimum 6 feet of social distancing is still required while in active physical education, at lunch, and recess.

CCSD21 will still consider the use of an Adaptive Pause at the classroom, school, or district levels if COVID-19 spread in the community reaches such a significant level and/or if an order to return to remote learning is issued by the Governor, Illinois State Board of Education, or state or county public health officials. Any decision to return to an adaptive pause will be made with a solid understanding of trending data, including current rates of exclusion or confirmed cases within our schools, and with as much advance notice given to families as possible. Please continue to consider your family’s contingency plan should a close contact occur, or should closure occur at the classroom, school, or District level.

2020-2021 school year plans

CCSD21’s hybrid in-person learning plan, outlined below, went into effect on October 5, 2020:

CCSD21 began the 2020-2021 school year with full-time distance learning for all students. View the plan:

CCSD21 initially planned to welcome all students back in person to begin the school year. However, guidance and data at that time could not allow the District to safely move forward.


Distance Learning Academy or home/assigned school enrollment

For the duration of the 2020-2021 school year, School District 21 is maintaining a full-time Distance Learning Academy. Parents received a detailed explanation (explanation image) on July 31 about the Distance Learning Academy, remote instruction for all students, and the resumption of in-person learning. Families elected in August to enroll their child(ren) in the Distance Learning Academy or in remote learning with their home/assigned school.
