[5] The Maine Department of Education also ranks Wells High School in the top 10 statewide, and #1 in York County.

The law gave towns the ability to establish public high schools which would receive 50% of their funding from the state.

In 1901, voters at the annual town meeting were asked whether they wanted to build a standalone high school.

It was designed by the Maine architectural firm of Miller & Beal, Inc.[8] In 1939, the 1909 building was completely destroyed by fire, and was not rebuilt.

[8] In 1999, the auditorium underwent interior renovations and was named in honor of Valjeane Olenn, who served as principal of Wells High School from 1986 to 1998.

Wells High School celebrated its 100th graduating class in 2003 — which was also the 350th anniversary of the town's incorporation.

[3] In November 2013, voters in Wells and Ogunquit approved a $27 million renovation/expansion project for the high school, to be funded solely by taxpayers in the two towns.

Electrical, plumbing, heating, ventilation, and computer network systems were refurbished or replaced.

In 2014, Wells High School announced plans to phase out certain visual aspects of the Warrior mascot — specifically the stereotypical profile of a male Native American person's head — in favor of different imagery, such as a stylized "W," in an effort to focus less on any specific race or ethnicity.

[12] As of 2016, however, certain renovated and newly constructed areas of the building, such as computer labs and the entrance to the athletics wing, prominently feature the "Indian head" image.
