Basis Chandler, Chandler AZ - Test Scores & Data

Original Research by School Decision on Basis Chandler

BASIS Chandler is a charter school serving grades five through twelve in the Phoenix suburb of Chandler. It is part of the BASIS Charter Schools network, a well‑known chain of academically demanding institutions. The school’s location on South Arizona Avenue places it in a city that has grown rapidly into a major technology and semiconductor hub, anchored by employers like Intel, Wells Fargo, and Northrop Grumman. Chandler’s built environment is car‑oriented, with master‑planned subdivisions, freeway corridors, and a smaller historic downtown.

Academically, BASIS Chandler performs at a level that puts it among the strongest schools in Arizona. On the state’s AASA assessments, proficiency rates in math and English language arts are consistently well above the state average and stand in the top quarter of all districts in Maricopa County. In the middle grades, the share of students reaching proficiency in math is near universal, and English language arts scores are similarly high. Science results from the AzSci test show strong performance in both fifth and eighth grades. Because the data covers only one school year, there is no multi‑year trend to examine, but the single snapshot is unmistakably strong.

The school’s enrollment is roughly mid‑sized for the grade span it covers, with a noticeable drop in the high school grades compared to the middle school. The student body is distinctive in its composition: the large majority of students are Asian, with smaller shares of white students and Black students, and very few Hispanic or Native American students. Data on economic disadvantage, special education, and English learner status were not reported, so a parent cannot gauge how well the school serves those populations from this information. Similarly, no graduation rate was available despite the school serving grades eleven and twelve; a family may want to ask the school directly about its four‑year graduation outcomes and college‑going rates.

The school is a charter, meaning it operates independently of the local unified school district and has its own admissions process. The parent district, BASIS Charter Schools Inc., was not found to have any recent public changes that would affect families. Chandler itself is a high‑cost housing market, with typical home values above state and national medians and rents that reflect the area’s desirability. The economy is strong and anchored by high‑technology manufacturing, which shapes the pool of families who live in the community.

For a family considering BASIS Chandler, the academic picture is clear: this is a school where proficiency is the norm, and expectations are high. The peer group is heavily Asian, which may matter to families looking for that kind of environment. The absence of data on student support programs and graduation outcomes are gaps worth pursuing. The school’s charter status, strong test results, and location in a tech‑driven suburb make it a fit for families who prioritize rigorous academics and are comfortable with a largely homogeneous student body by race and ethnicity.

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.
