Above: I put together info from the public school calendars with a focus on Southborough schools and both high schools.
If you have kids in our public schools, it’s time to mark your calendars for the coming year.
As parents and students should know by now, school is back in session in less than two weeks. But some schools have events that take place leading up to it. And it’s not long until holidays and half days begin to pop up.
To make it easier for Southborough families with kids in our public schools, especially readers with kids in multiple schools, I’ve put pulled and combined the key dates for Southborough K-8 and Algonquin Regional High School (ARHS) that you may want to enter in your calendars for future planning. I also included Assabet Valley (AVRTHS) as our town’s alternative regional technical high school.
This should cover all of the half days and days off for the school year, plus most of the events that are for parents (like Curriculum Nights). For the first couple of months, I also included the special nights introducing parents to sports and music programs, etc.
The NSBORO Schools calendar includes religious holidays that not everyone celebrates. To help working families out, Southborough Recreation is planning to offer one-off programs on some of the days for some of the grades. Registration opened today for the first ones — on October 2nd (Yom Kippur) and October 20th (Diwali).
