This study investigated the psychometric properties of a group-administered early literacy measure, the Mountain Shadows Phonemic Awareness Scale (MS-PAS), using a kindergarten sample (N = 213). The MS-PAS was compared to the "Test of Phonological Awareness-Second Edition: Plus" (TOPA-2+). Results indicated excellent internal consistency for the MS-PAS, as well as adequate convergent and predictive validity. The MS-PAS was found to be an adequate measure for determining which students are unlikely to need additional instructional services in reading. The MS-PAS and TOPA-2+ had highly similar psychometric properties. Recommendations are provided for using the MS-PAS in a multistep screening process. (Contains 3 tables.)
