It was renamed The Carleton Military School in approximately 1901. Carleton still held the position of principal, but a Major Baker ran the military instruction, having previously been a military instructor at Harvard University summer school. Carleton died 8 August 1902, two months after the expected end of the school year. The location of the school continued to be used as a boarding house, called the Carleton House for Boys and Young Men in approximately 1925. The school buildings still stand near the corner of Chadwick and South Main Street in Haverhill, and are used as apartments.
