We used multidimensional item response theory to test the internal structure of the Phonological Awareness Literacy Screening in Spanish for Preschool and test for item parameter drift. The measure is aligned with the simple view of reading, which defines reading as consisting of two equally important dimensions: decoding and language…

The current study explored a possible continuum of spelling features that children receiving literacy instruction in Spanish might be expected to master in Grades 1-3. We administered a developmental spelling inventory representing nine distinct Spanish spelling features to 864 students in bilingual and dual language schools across the U.S.…

The goal of the current study was to determine whether Concept of Word in Text (COW-T) predicts later sight word reading achievement in Spanish, as it does in English. COW-T requires that children have beginning sound awareness, automatic recognition of letters and letter sounds, and the ability to coordinate these skills to finger point…

This study explored the viability of using kindergarten measures of phonological awareness, alphabet knowledge, and orthographic knowledge, administered in English, to predict first grade reading achievement of Spanish-speaking English language learners. The primary research question was: Do kindergarten measures of early literacy skills in…

This study explored heterogeneity in literacy development among 2,300 Hispanic children receiving English as a Second Language (ESL) services at the start of kindergarten. Two research questions guided this work: (1) Do Spanish-speaking English language learners receiving ESL services in the fall of kindergarten demonstrate homogeneous early…

We investigated the latent factor structure of the "Phonological Awareness Literacy Screening for Kindergarteners" in Spanish ("PALS español K"). Participants included 590 Spanish-speaking, public-school kindergarteners from five states. Three theoretically-guided factor structures were measured and tested with one half of our…
