The State of Utah has added 8 additional dual language immersion programs since Fall 2014. 5 are Spanish. 3 are Mandarin.
Utah has posted its list of dual language immersion school (here, dated 7/18/16). Data for Oregon is from my 2014 count (here) with the addition of 17 Literacy Squared programs in the Salem-Keizer School District (here). I have not updated my 2014 Oregon count.
