The Bartlett School in Waltham, which closed earlier this year due to a decline in admission, has been sold to another school specializing in educating students with learning disabilities.

The Carroll School, a primary school for students with diagnosed learning disabilities such as dyslexia, will use the newly acquired property as an expansion to its main campus in Lincoln, according to a statement.

Executive Vice President James Elcock and Assistant Vice President Katharine Barry of Colliers Meredith & Grew negotiated the sale of the 58,000-square-foot, 5.8-acre campus on Trapelo Road.

Financial details of the transactions were not disclosed, but the property was assessed at slightly more than $5.5 million for fiscal 2009, according to data obtained from The Warren Group, publisher of Banker & Tradesman.

"A number of very interested parties were attracted to the Bartlett School once the property became available for sale. The Bartlett School trustees are thrilled to finalize a transaction with the Carroll School, where educating children will continue," said Elcock.

The two-building campus consists of a 50,156-square-foot, single-story brick school building with functional lower level and a 7,830-square-foot, state-of-the-art gymnasium constructed in 2004-2005.
