Richard Lemons, executive director for the Connecticut Center for School Change, gives an update on the effort to create a new strategic operating plan for Norwalk Public Schools, Tuesday at the Board of Education meeting. NORWALK, Conn. — The dates for high school graduations and middle school promotion ceremonies are set, but the exact number of people who will be allowed at each are still up in the air, Norwalk Public Schools Superintendent Alexandra Estrella said at the Board of Education meeting on Tuesday. The ceremonies will be most likely outdoors, she said. “The numbers are going to depend on the cases around that time,” she said. “Right now, we have restrictions in terms of how large the groups can be. And we’re also even trying to organize prom and taking these numbers into account. So it’s a day-by-day situation right now.”
