There is one public school in Sherman named the Sherman School which has about 500 kids and runs from pre-school up to grade 8. There is no high school in Sherman therefore students are given the option to choose from six high schools that the town will pay for them to attend (they include: New Milford High School, New Fairfield High School, Brookfield High School, Henry Abbott Tech, Shepaug High School, and Nonnewaug High School).

Sherman is the location of the Naromiyocknowhusunkatankshunk Brook (29 letters), on the north end of town near the New Milford border. The Indian name means "water flowing from the hills," (the English wording is 17 letters long). The Naromi Land Trust in Sherman derived its name from the brook.

For some time the brook was officially known as "Morrissey" Brook (9 letters), but an official name change was put into Public Act 01-194, "An Act Concerning Certain Real Property Transactions," which was approved July 11, 2001. The 29-letter name was noted in an 1882 book, History of the Towns of New Milford and Bridgewater, 1703-1882, by Samuel Orcutt.
