Under the latest screening plan, students and staff will test themselves using PCR tests, which are considered the gold standard for COVID-19 testing. Elementary and middle school students will use a short swab in the inside edge of their noses. All the tests will be pooled according to their classrooms, and processed by a company. The results for the pool will be given to city schools. If the pool test is positive, all the students and staff will be notified and will have to quarantine. Families will be invited to come back for an individual test.
