Revised COVID-19 Testing Plan

March 10, 2021

Dear Graded Community,

I am writing to share an improvement that we are making to our saliva-based PCR testing program this week. This new protocol should simplify the process for parents.

Students in K3, K4, and K5 who are on campus each week and students in grades 1-5 who are on campus for consecutive weeks:

  • Tests will be distributed to students during school hours on Thursdays to place in their backpacks and take home. 
  • Students must complete the saliva test on Friday mornings before breakfast, register the barcode on the Medelics site at, and bring the completed test to school. 
  • Students will drop off their test upon entering Graded in a Test Kit Drop-off Box. The school will send it to the lab, eliminating your need to participate in the drive-thru testing process.
  • The testing packet will include a sheet with detailed instructions.

Students on campus every other week:

  • Students will receive a take-home test each Friday they are on campus to be used prior to their next session on campus.
  • Students must complete the saliva test the following Friday -- and no earlier than that.
  • You may return your child’s completed test to Graded’s Main Parking Garage dropbox on Friday between 8:00 am - 5:00 pm, or Saturday between 8:00 am - 10:00 am. 
  • Alternatively, you may send the completed test via courier directly to the Mendelics Lab (located at Av Braz Leme, 1631, Casa Verde - CEP: 02511-000). It must arrive at the lab between 9:00 am on Friday, and 11:00 am on Saturday, the weekend before your child attends on-campus classes.
  • The testing packet will include a sheet with detailed instructions.

Students who were NOT at Graded during their prior on-campus session

  • If your child was not on campus during their prior on-campus session, they must follow the current testing schedule by picking up the take-home test at Graded or participating in drive-thru testing in the Main Parking Garage on Fridays between 4:00 - 8:00 pm.

Your child must complete the test within the required timeline to ensure it is valid and renders an accurate result. Also, it is essential that you register the barcode on the Mendelics website at before submitting your test.

We appreciate your assistance with your child’s COVID-19 testing.
