Diagnostic Decoding Survey Case Studies

These case studies discuss the Diagnostic Decoding Survey scores for four students at different grade levels, including an analysis of the survey data and suggestions or recommendations for further assessment.  The Diagnostic Decoding Surveys and other information presented are taken from actual students, but the names have been changed.  

Felicia –1st Grade

Brittany –5th Grade

The Beginning DS and Advanced DS were administered to Brittany because she scored at “Basic” on the reading portion of her fourth grade state assessment.  Her mother wanted to find out why she was not scoring higher on her state test because Brittany had been administered a battery of assessments that identified her IQ as 120.

Roy –9th Grade

The Beginning DS and Advanced DS were administered to Roy because he was acting out in class and not turning in his homework.  Although all of Roys other teacher’s said that he was just not motivated, his language arts teacher had been to a Really Great Reading workshop about the Diagnostic Decoding Surveys and she decided to administer them to learn whether Roy’s behavior problems might be related to a reading problem.
