Especially encouraging are the new studies of the test’s sensitivity, specificity, and ROC/AUC.

The Test of Written Spelling–Fifth Edition (TWS-5) is an accurate and efficient instrument that uses a dictated-word format to assess spelling skills in school-age children and ado- lescents. It has two forms that can be administered in 20 minutes, either individually or in groups. Each form contains 50 spelling words drawn from eight basal spelling series and graded word lists. The TWS-5 provides percentiles, standard scores, and age and grade equivalents. The Answer and Record Form offers a convenient way to record and keep track of scores, summarize the results, and indicate any comments and recom- mendations.
