Saratoga County is expanding its “Test to Stay” (TTS) protocol to school districts countywide to allow more students to remain in the classroom during COVID-19. WRGB reports it’s a test-based protocol protocol program for students from preK-12 who have been exposed to COVID-19 in school or on a school bus that allows them attend classes in person rather than quarantine at home. Many school districts in Saratoga County will begin offering the program this week.
