Curriculum - Based Measurement of Written Expression at the Secondary Level

11 A literature review of all research conducted on CBM of written expression at the secondary level was completed. Findings indicate that CWS and CWS-ICWS have the best criterion-related validity for this population, and these measures can be used with accuracy for screening purposes. Results also indicate that seven minute writing samples meet reliability and validity standards, and seven minutes may be the best administration time for CBM purposes, but more research needs to be completed. Further, findings are very limited regarding the use of CBM measures of written expression with students receiving special education. Further research is needed to examine CBM measures of written expression at the secondary level to determine their technical adequacy for students receiving special education.
