Indian Creek School was founded in September 1973 by educators Anne Coleman Chambers and Rebecca Randolph.

[4] Coleman Chambers's parents donated land for the new school, which was constructed on a 17-acre (0.069 km2) campus on Evergreen Road in Crownsville, Maryland.

Her brother, Tracy Coleman, Jr., assisted in construction and later served as Indian Creek's Director of Transportation and Physical Plant.

Indian Creek's founders had not originally planned to establish an upper school, focusing instead on pre-K through eighth-grade students.

[11] The road constructed to provide access to the new Upper School building was named after founder Anne Coleman Chambers.

Students can take Spanish or Latin on-campus, or study Japanese or Arabic through the Global Online Academy.

[21] Founders Anne Coleman Chambers and Rebecca Randolph based Indian Creek School's educational approach on research in neuroscience and cognitive development.

[22][23] Under Coleman Chambers and Randolph, Indian Creek School began teaching Spanish and computer classes, starting at the kindergarten level, before this was common.

Coleman Chambers saw the camp as part of Indian Creek School's mission of giving back to the local community, particularly wanting to help kids who could otherwise be missed in large classroom settings.

In the camp's human development classes, campers discussed decision-making, college, and challenges facing kids their age.

STARs also began offering scholarships to Indian Creek School to some campers; full tuition in that year was $21,000.

Former Indian Creek School student Will Bartz became involved with STARs in 2005, after growing unsatisfied with his job as a financial adviser and returning to Coleman Chambers for advice.

[26] Under Coleman Chambers, a "Character Counts" program was developed at the Indian Creek Lower School to impart values including respect, kindness, honesty, and responsibility, while middle school students began starting each year with fall camping trips, designed to promote team-building and student-faculty interaction.

[20] The Indian Creek Eagles compete in eleven varsity sports: sailing, cross country, equestrian, field hockey, soccer, volleyball, basketball, baseball, golf, lacrosse, and tennis.

[20] In 2016, Indian Creek completed construction on a $4 million athletics complex with two turf fields, tennis courts, and a baseball diamond.

[32] Indian Creek's campus also contains a 3.1 mile wooded cross country trail and a marley-floored dance studio.

[30] Other extracurricular groups at Indian Creek School include Gay-Straight Alliance, a Key Club International chapter, Model UN, and other student organizations.
