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 adolescents. It has two forms that can be administered in 20 minutes to 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, 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.
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
- To serve as a measure for research efforts designed to investigate spelling
