An accurate, efficient dictated assessment of spelling skills.

Stephen C. Larsen, Donald Hammill and Louisa Moats

Age Range: 5 through 18 years
Time: 20 minutes

The TWS-5 has two forms, which can be administered either individually, or to groups, in about 20 minutes. Each form contains 50 spelling words, drawn from eight basal spelling series, and graded word lists.  The Answer and Record Form provides a convenient way to record scores, summarize results, and indicate comments and recommendations.

The TWS-5 can:

  • Identify students whose scores are significantly below their peers, and might need intervention
  • Document overall progress in spelling, as a result of intervention
  • Measure research efforts to investigate spelling

Normed on a representative sample of 1,634 students from 23 U.S. states, the analyses show no gender or racial bias in the TWS-5 items. Test reliability was studied in various ways: coefficient alphas; alternate form (immediate administration); test-retest; alternate form (delayed administration), and interscorer. All coefficients are over .90, which indicates the test’s high reliability. Additional studies confirmed the TWS-5's content-description, criterion-prediction, and construct-identification validity.  Especially encouraging are the new studies of the test’s sensitivity, specificity and ROC/AUC.

 

The TWS-5 Kit includes 50 TWS-5 Answer and Record Forms, a laminated, double-sided Card with Stimulus Words and a Manual, in a storage box.
