International Charter School of Atlanta, Roswell GA

Original Research by School Decision on International Charter School of Atlanta

International Charter School of Atlanta is a dual-language immersion school serving kindergarten through 8th grade across two Fulton County campuses: a Lower Campus in Roswell (K-3) and an Upper Campus in Alpharetta (4-8). The school operates as a state charter authorized as an IB World School for both the Primary Years Programme (K-5) and the Middle Years Programme (6-8), meaning students follow a continuous International Baccalaureate framework from entry through middle school. Language instruction happens in French, German, Mandarin, or Spanish, taught by native speakers alongside English.

The school has grown substantially over the past decade and now operates at or near full enrollment. New admissions for the coming school year are limited to kindergarten and a small number of seats in grades 1-3, with those upper-grade openings requiring demonstrated language proficiency through the STAMP 4Se assessment. This capacity constraint directly affects families considering enrollment of older children; the school is not an option for mid-stream entry into upper grades unless a child already speaks one of the immersion languages at a measurable level. The state charter was recently renewed through 2030, securing the school's operating authority and dual-language program for the next five years.

On state testing, the school shows mixed performance across its tested grades. In English language arts, the school performs above the midpoint among Fulton County's schools overall, with particularly strong results in grades 4, 5, and 7. Sixth-grade ELA dips slightly but remains proficient for most. In mathematics, the school shows strength through grade 5, where proficiency peaks, but sixth-grade math drops to roughly half the school proficient, and seventh and eighth grades remain below the school's fifth-grade performance. Science proficiency in the available grades (5 and 8) is solid, and eighth-grade social studies proficiency sits at roughly the midpoint statewide. The pattern suggests a meaningful challenge in the transition to upper-middle grades, particularly in math, which a parent may want to look into further with the school. Whether this reflects curriculum shifts associated with the MYP implementation, the structure of the two-campus model, or other factors would be worth exploring directly.

The student body is racially and ethnically mixed, with no single group forming a clear majority. White students and Hispanic students each represent a substantial share, Black and Asian students together account for meaningful enrollment, and smaller numbers of multiracial students round out the composition. Free-and-reduced-price-lunch data was not available, so economic diversity cannot be measured from the data at hand.

Roswell itself is an affluent suburban community roughly 20 miles north of downtown Atlanta, anchored by a historic downtown district around Canton Street with shops, restaurants, galleries, and an active street life, surrounded by established single-family neighborhoods of mid-to-late-20th-century ranch and brick homes alongside newer construction and townhomes. Housing values in the area are moderately above the state benchmark, and rents have remained relatively stable. The city is undergoing downtown revitalization with mixed-use infill projects, including the Hill Street development with multifamily apartments and commercial space, and the Southern Post project adding office, retail, and luxury housing. Major employers include Kimberly-Clark, GM's IT Innovation Center, North Fulton Hospital, UPS, and a concentration of healthcare and IT firms. The community is largely car-oriented outside the historic district's walkable core, though MARTA bus service connects Roswell to the North Springs rail station. Parks, trails along the Chattahoochee River, and the Chattahoochee Nature Center anchor civic life.

A parent considering International Charter School of Atlanta should weigh the IB curriculum framework and immersion language instruction as core features shaping the school's identity and appeal, understand that enrollment is capped and older-child entry is not feasible unless the child already speaks one of the offered languages, and recognize that middle-grade math performance warrants conversation with the school about support and curriculum progression. The school is well-suited to families seeking an IB-aligned, language-rich environment and comfortable with a two-campus structure; it is not a fit for families seeking open enrollment at upper grades or those not committed to language immersion.

Graduation rate (ACGR) reflects the federally published Adjusted Cohort Graduation Rate for the most recent year available. We refresh this data annually at the close of each academic year in June. The federal source publishes a banded rate (for example, "90-94%") instead of an exact number for cohorts small enough to risk identifying individual students. The state distribution chart, where shown, plots every school in the state with a published rate or band; schools whose rate is federally suppressed are excluded. Where the federal source publishes a band rather than an exact rate, the school is placed within its band using a stable, ID-derived offset, so its position is consistent across visits.
