[clarification needed] In 1801, the General Court of Massachusetts established Lincoln Academy to promote "Piety, Religion and Morality".

Lincoln Academy opened in October 1805 in a wooden building on River Road in Newcastle with 74 students.

The Maine Legislature then passed a law that mandated secondary education be funded by the local towns.

Today, Lincoln Academy serves as a private high school for students from surrounding towns.

[3] On April 17, 2015, Lincoln Academy opened a newly constructed Cable-Burns Applied Technology and Engineering Center (abbreviated as ATEC) and a new dormitory for residential students.

The ATEC building offers flexible, modern classroom space for traditionally-offered courses such as Digital Media Production, Small Engines, Digital Photography, Human Anatomy and Physiology, Computer-Aided Design (CAD), as well as new courses such as Engineering, Invent to Learn, and Metal Sculpture.

[4] Also in 2015, a new synthetic surface sports field was opened, named after Lincoln Academy graduate, William A. Clark II.
