Each small school followed an instructional model of teaching core subjects of Ohio class requirements.

In 1987, Lima Senior High School began formally recognizing the accomplishments of its alumni who had received local, state or national recognition for achievements in their occupational fields, made significant contributions to society, or performed meritorious service for our country by inducting them into the Lima Senior High School Distinguished Alumni Hall of Fame.

All Hall of Fame inductees have their portraits displayed in Lima Senior Highschool's cafeteria.

Lima Senior has maintained a full arts department in the high school.

All groups in the music department are by audition only, at the discretion of the individual directors.
