This study was conducted over three years. Children from 22 different languages received GrapeSEED. The assessment measure used in this study was the World-Class Instructional Design and Assessment (WIDA).
The WIDA Consortium (World-Class Instructional Design and Assessment – WIDA) is an educational consortium of state departments of education. Currently, 33 U.S. states participate in the WIDA Consortium. WIDA designs and implements proficiency standards and assessment for grade K-12 English learners.
National research shows that children typically take 6–8 years to reach grade level proficiency. GrapeSEED students, however, reached proficiency in speaking and reading in just 2–3 years.
The students’ proficiency as evidenced in their WIDA scores reflected the natural progression of children learning language.
Listening comes first because the children have to be able to hear the words of the language before they can speak. The kindergarten students were certainly successful in listening.
Next comes speaking. The research showed that the first and second graders scored high in speaking and oral language.
And finally, by the third grade, children should develop reading skills. The GrapeSEED students achieved reading proficiency by the end of second grade.
