The school was renamed Montessori School of Fort Worth in 2013 to more accurately describe the ages that the school currently serves: 18 months through 14 years.
In 2014, additional space was added to the North building to bring the two toddler programs into close proximity and enlarge the North primary class. During the summer of 2015, another lower elementary building was added to accommodate the continued growth of the lower elementary program. The two classes, north and south lower elementary, work in tandem, following the same schedule and sharing field trips.
During the 2016-2017 school year, the upper elementary classroom moved into a newly acquired building on Clayton Road to allow for more classroom space. The former Upper Elementary building is now used as a community room.
At the end of the 2017-2018 school year, the original North Building was remodeled to provide an updated kitchen area, open up space in the North Primary class and add additional administrative space.
