The Test of Written SpellingFifth Edition (TWS-5) is an accurate and efficient instrument that uses a dictated-word format to assess spelling skills in school-age children and adolescents. It has two forms that can be administered in 20 minutes to either individuals 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, 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 recommendations.
Administration and Scoring
The TWS-5 can be administered in 20 minutes to either groups or individuals. Scores may be reported as standard scores, percentiles, spelling ages, and grade equivalents. The TWS-5 was standardized on a nationally stratified normative sample.
The results of the TWS-5 can be used for three specific purposes: to identify students whose scores are significantly below those of their peers and who might need interventions designed to improve spelling proficiency, to document overall progress in spelling as a consequence of intervention programs, and to serve as a measure for research efforts designed to investigate spelling.
