We believe that each child is unique. We have created a school environment that is safe, secure, and that addresses the needs of all students. In addition to our strong academic programs that challenge students and provide them with a solid foundation for learning, we stress the development of social skills that encourage confidence, self-esteem and healthy interactions with others.


We have high standards for our students. We want them to have the skills to be successful in society, and also the humanity to contribute to an improved world. Please join in a partnership with us as we work toward these important goals.  We strive for an excellent relationship among children, parents and teachers working together to make each year a success.

Thomaston Grammar School's Carnival-Themed Fall Fest

This year’s annual Thomaston Grammar School Fall Fest was awesome!  The carnival-themed event, which was sponsored by the Friends and Family of TGS group, had a wonderful turnout.  Approximately 150 children attended along with a parent or other family member.  There was a photo booth where students and their friends and/or families could get photos taken by Principal Riley.  Families had a great time using the backdrop and props to make it look as though they were at a carnival.  From there, students were able to play a variety of games, and keep playing until they won, in order to earn some fun prizes.  There was a balloon artist who put on a spectacular show midway through the event.  He even transformed some TGS students into things like a butterfly and a viking.  He also made marvelous balloons creations for each child who attended the event.  Students could get their faces painted.  There was free fresh-popped popcorn for all and baked goods and cotton candy for sale for those who wanted it.  There were also some great door prizes.  A fun time was had by all!
