Dallas ISD plans newcomer centers for high schoolers learning English and revamp of dual-language programs Changes are aimed at better serving students learning English. Dallas ISD is planning changes to the district's dual-language programs and a new pilot program for high school newcomer students. Students struggling to learn English will get greater support on their path to become biliterate if Dallas schools create newcomer centers for high schoolers and revamp dual-language programs, officials said. The proposed changes come more than 15 years after Superintendent Michael Hinojosa was first hired to lead the district and when DISD began exploring better ways to serve students learning English.
