Evansville Christian School

Since August 2017, ECS has operated a pre-kindergarten campus at Crossroads Christian Church.

ECS' original "east campus", serving students from pre-kindergarten to fifth grade, was located on Lincoln Avenue inside Bethel Church. The "north campus", serving students from kindergarten to second grade, was located on Millersburg Road inside Christian Fellowship Church. Both of these campuses are no longer in use. Preceding the 2021/22 school year, a second, free-standing campus was built near the intersection of Epworth Road and Lincoln Avenue to accommodate students from kindergarten to sixth grade.

Preceding the 2015/16 school year, both ECS's elementary and junior high students studied at the original east campus. However, as class sizes began to grow, the school worked up a partnership with First Southern Baptist Church to accommodate a middle school campus. As of the 2021/22 school year, the Cullen campus consists of seventh and eighth grade students.

Talks of establishing a high school began in the early 2010s. In 2014 and 2015, the school board began raising money for a free-standing high school campus on a 16-acre site near the intersection of Epworth Road and Lincoln Avenue. They began construction in early 2016 and accommodated their first freshman class of high school students at their middle campus on Cullen Avenue. The new Epworth campus opened up to begin the 2017/18 school year. The high school site was a 43,000 square foot building with eight flexible learning spaces, two large science laboratories, large music and art rooms, a full-size gym, and a commons area.

As of 2021, the ECS board was rumored to have begun informal talks about purchasing the former site of Tudela Soccer Complex, a six-acre piece of land near the intersection of Epworth Road and Telephone Road. The athletic complex serves as the current home facility for the ECS soccer program. Purchasing land in this vicinity would bring the possibility of constructing a new, high school campus on these grounds and housing junior high students at the current high school campus.
