WICHITA, Kan. (AP) — The Wichita school district, already one of the most ethnically diverse in the state, is undergoing more changes.

In the last two years the district has seen an increase in students who have never lived outside a refugee camp, many of whom speak Arabic and Swahili.

The Wichita Eagle reports that has created new challenges for teachers and administrators. Because federal law requires schools to provide information to parents in the language they prefer, an Arabic speaker is on call to help teachers and other staff communicate with families.

The district also uses a service that lets teachers quickly connect by phone with parents in any language. It has more than 350 students from other countries this year, with another 160 students who speak minimal English from other states.
