What is the validity of SPELL 2?
To establish criterion validity, the extent to which SPELL: Spelling Performance Evaluation for Language and Literacy (First Edition) performance scores correlate with scores on the Test of Written Spelling-4 (Larsen, Hammill, & Moats, 1999) and on two subtests of the Woodcock Diagnostic Reading Battery (Woodcock, 1997) was measured for 135 students in Grades 1-6. Results from Pearson-r correlations and a simultaneous multiple regression analysis indicate that SPELL validly measures students’ spelling abilities, decoding skills, and identification of sight words and that SPELL can be used to identify word study goals in a variety of grades and settings (Mooney & Masterson, 2006). A validity study is currently underway to establish criterion validity for SPELL – 2.
