Punnichy has an elementary school, high school and has a Carlton Trail Regional College centre. Punnichy Community High School is unique within the Horizon School Division, in that it is run on the pentamester system, with five terms in a school year. The students take two classes each pentamester, one all morning and one all afternoon. Each pentamester is roughly 38 days long. A satellite facility of Punnichy high school is the George Gordon Computer Education Centre located in the community centre on Gordon First Nation. The facility assists First Nations students to return to school or pick up extra classes to move into post-secondary or job training. The program is "at your own pace" and is similar to "store front" programs in urban centres.
The town has one of the largest RCMP detachments in the area.
