Language screener
preLAS 2000 (Duncan & De Avila, 1998)
DLL students’ English language skills are screened using the Art Show and Simon Says subtests. Art Show screens students’ expressive language skills and Simons Says screens their receptive skills. Both subtests contain 10 items. During the Art Show students are shown a series of pictures and they are asked to name the item and in later trials asked to tell what the item does. In the Simon Says subtest, students are asked to do complete a series of tasks (e.g., “Simon says turn the paper over”) The PPVT-5 assesses students’ English receptive vocabulary skills. Students are shown pictures of several items and asked to point to a particular item. The EOWPVT-4 is a measure of students’ English expressive vocabulary and the EOWPVT-SBE is a measure of students’ Spanish expressive vocabulary. During this assessment students are presented with pictures and asked to name items and actions. Students’ literacy skills were measured using the Letter-Word Identification or Identificación de letras y palabras subtests of the Woodcock-Johnson IV and Batería IV, respectively. During this assessment students are presented with a testbook and asked to identify letters and to read words.
