May Calendar


Participation in the screening program is  mandatory  for all students participating in on-campus hybrid instruction or extracurriculars

  • Saliva samples dropped off by 2 p.m. on Sundays, or Noon on Monday, Tuesday, or Wednesday will be screened that day, and students who are being referred for a PCR test and must stay at home will be notified by early the next morning. All other students will not get a notification and may attend school. Samples dropped off after 2 p.m. on Sundays, or Noon on Monday, Tuesday, or Wednesday will be screened the following day.
  • It can take up to 48 hours for PowerSchool to show that a student submitted a saliva sample. Again, students who must remain home and are referred for a PCR test already will have been notified of their status on the day their sample was screened.
  • Samples should be collected as close as possible to the time when you will drop them off. However, you may collect samples the day before and drop them off the following morning. This will not affect results. Please do not eat or drink for 30 minutes before collecting your sample.

Drop-Off Days and Times

Starting February 21, all students should drop off on the days/times designated by the first letter of their last name. There is no longer a separate drop-off requirement for extracurricular/athletic participation. 

Families should not drop off samples early. Please drop off only in the window designated by your student's last name.

Purpose of Weekly Saliva Screening

New Trier's COVID-19 screening program has several goals, including:

  • Reducing school closures and quarantines and allowing for more in-person instruction.
  • Identifying potential cases of COVID-19 in the school population early, reducing transmission.
  • Driving down overall rates in our community by alerting those who may need to quarantine before they show symptoms.
  • Providing a family and personal benefit for participants of knowing their potential COVID-19 status at the time of submission.

Studies have shown that weekly screening programs have driven down transmission rates in the areas they cover. Without weekly screening, the main way New Trier has to assess the risk of COVID-19 coming into our buildings is by looking at metrics for New Trier Township (where students live and socialize) and the larger area in which staff live. With weekly screening, New Trier has a more accurate assessment of COVID-19 rates and risks on campus and within the school population, providing an extra layer of reassurance for offering in-person instruction in addition to the many mitigation measures the school already has in place on both campuses that make the risk of in-school transmission low.

Exclusion from On-Campus Learning

We will monitor weekly submissions, and students who do not submit their weekly saliva sample will be excluded from Ruvna and will not be able to come on campus. Parents will be notified via email when saliva samples are missing. Students who consistently fail to submit saliva samples will be reassigned to remote instruction. 

While New Trier will make every effort to ensure that all students on campus are screened within the last seven days, we cannot guarantee that all individuals on campus will have been screened or that there will be no instances of COVID-19 on campus. In addition to the screening program, New Trier implements other strong mitigation measures such as mask wearing and social distancing to prevent the spread of COVID-19. 

Objection Process

Parents who want their student to participate in hybrid instruction but object to their student participating in the screening program or who wish to challenge their student's assignment to remote instruction for failure to provide saliva samples may request a meeting with their campus principal. The student will be assigned to remote learning pending the outcome of the meeting.
