The measures administered over the course of the study included both researcher- developed tests and standardized tests of the components of reading described above. The researcher-developed tests included the following: a phonology test and a phonemic segmentation task (phonological awareness); a letter, word, and pseudoword naming task (word reading); and tests of cognate awareness and morphological awareness (word knowledge). It should be noted that the scores used for letter, word, and pseudoword reading were reading efficiency scores created by combining reading accuracy with reading speed. The standardized tests administered included the Woodcock Language Proficiency Battery.
