This study was a preliminary examination of the psychometric properties of a newly developed Spanish translated version of the "Gifted Rating Scales-School Form (GRS-S)". Data was collected from elementary and middle schools in northeastern Puerto Rico. Thirty teachers independently rated 153 students using the "GRS-S" Spanish Form. Results indicated strong internal consistency for teacher ratings with alphas ranging from 0.98 to 0.99. Intercorrelations between scales are moderate to strong, ranging from 0.88 to 0.97. Factor testing of two separate models supported a six factor model proposed by authors of the "GRS-S". Results provided initial support for the "GRS-S" Spanish translated version as a reliable and potentially useful screening measure to assist in the identification of island Puerto Rican gifted students.
