Normative Data

Normative Data

The DESD consists of three sections: Decoding, Encoding, and Letter Writing. The Decoding section provides a norm-referenced measure of sight-word recognition (Reading Standard Score). Additionally qualitative indicators in the Encoding section allow you to distinguish deficits in sight-word recognition from deficits in phonetic analysis.

The normative sample consists of 678 students in grades 1 through 8.
