The AISD pre-K program advanced nearly one-third of students to above the national average in receptive vocabulary ability in their native language by Spring 2012, with more than 50% of students scoring above the national average on the test.
Prekindergarten Evaluation Series: Peabody Picture Vocabulary Test Performance by Vertical Team 2010-2011
Although pre-K students average gains on the 2010-2011 PPVT/TVIP significantly differed by vertical team, these differences were attributed more to the students’ school or classroom rather than to the vertical team in which a school resides.
In 2012-2013, AISD pre-K students demonstrated growth in receptive vocabulary on a nationally-normed test. Students enrolled in multiple programs showed greater growth in receptive vocabulary in their native language than did other pre-K students.
Although more than a third of tested pre-K students (37%) entered AISD one standard deviation below the national average in receptive vocabulary, the AISD pre-K program accelerated these students’ growth by nearly twice the national average.
AISD served 5,450 pre-K students in 2009-2010. Approximately 70% of sampled English-speaking pre-K students and 74% of sampled Spanish-speaking pre-K students had faster than the expected growth rate in receptive vocabulary.
