These are the appendixes for the report, "Progress of Arizona Kindergartners toward English Proficiency in Grade 3 by English Learner Student Classification." The study examined the English language proficiency and English language arts (ELA) proficiency (reading and writing at grade level) of non-native English speaker students in kindergarten and in grade 3. About 11 percent of 2013/14 kindergartners in Arizona were initially classified as English learner students. At the end of that school year, Arizona retested all non-native English speaker kindergartners after setting a higher threshold for English language proficiency. After reassessment, the proportion of kindergartners classified as English learner students rose to 18 percent. Students initially classified as English language proficient and reclassified as English learner students at the end of kindergarten were no more likely to achieve proficiency by the end of grade 3 than were students initially classified at the basic/intermediate (below proficient) level. This finding suggests that students who were reclassified likely needed English learner services at kindergarten entry. Four appendixes are included in the document.
