The DIBELS PSF is a standardized, individually administered test of phonological awareness for students in grades K-1. The PSF assesses the student’s ability to segment 3 or 4 phoneme words into their individual phonemes fluently. The PSF task is administered by the examiner orally presenting words of 3 to 4 phonemes. It requires the student to produce the phonemes for each word. For example, the examiner says “sat” and the student says “/s/ /a/ /t/” to receive 3 possible points for the word. The tool provides information on student performance in English. The test was normed using a national sample of 38,000 Kindergartners and 37,000 first graders. |
DIBELS -PSF takes 2 minutes to administer to individual students. 25 alternate forms are available for progress monitoring. Raw, percentile, and benchmark scores are available. Raw scores are calculated by adding the number of sound segments produced correctly in one minute. A composite score is provided along with instructional recommendations obtained by calculating the odds of achieving subsequent literacy outcomes from longitudinal research. A benchmark for end of kindergarten is 35 phonemes per minute. |
