North Wasco County School District 21 is considering establishing a pilot dual language immersion elementary school program in which students are taught in both Spanish and English, but Superintendent Candy Armstrong says they have a number of questions to answer before moving forward.  Armstrong says the biggest concern is whether it can be sustained over a long period of time.  Part of the exploration is how much it would cost to start and continue the program.  The program being considered would begin at the kindergarten level, and Armstrong adds the district is involving pre-schools in the discussion.  She emphasized the district has a lot of work to do to be able to start a dual language program.
