The Academic Performance Index (API) scores at the American Indian Public Charter School (AIPCS) showed significant improvement between 2000 and 2006. Under the leadership of Ben Chavis, a Native American professor, AIPCS students made considerable progress in academic scores during this period. By 2006, AIPCS' 196 students even surpassed the Piedmont Middle School, which had a much higher socioeconomic status. This achievement is particularly notable given the challenges faced by inner-city schools. The API scores' increase at AIPCS during this time reflects a positive trend in academic performance among its students.
