Washington Montessori School will host its fourth annual Polar Plunge for Partnership Dec. 6 at 11 a.m.

The family-friendly event, which is open to the public, will take place at Lake Waramaug State Park Beach.

It is a fundraiser for the school’s Community Partnership Program.

The event is open to children 6 and older.

The cost is $20.

Participants will receive a commemorative T-shirt and snacks.

The program provides middle school education to six graduates from the Children’s Community School in Waterbury each year.

The children who come to WMS have been identified as potential academic and social leaders within Waterbury.

They come from homes with limited financial resources.
