The Test of Written Spelling – Fifth Edition (TWS-5; Larsen, Hammill, & Moats, 2013) is an accurate and efficient instrument that uses a dictated-word format to assess spelling skills in school-age children and adolescents from 5 to 18 years old.
The test has two forms that can be administered in 20 minutes, either to individuals or to a group. Each form contains 50 spelling words drawn from eight basal spelling series and graded word lists. The results of the TWS-5 can be used to identify students whose spelling proficiency is significantly below their peers and who might need support; document progress in spelling improvements resulting from intervention; and serve as a measure for researchers studying spelling.
