The Wilson® Assessment of Decoding and Encoding (WADE) is a curriculum-based measure which specifically assesses a student’s decoding and encoding (spelling) skills correlated to the word structures taught in Wilson Reading System®. The WADE is aligned to the scope and sequence of the Wilson Reading System in order to both guide instruction and determine mastery.

The WADE consists of an Administrator’s Guide, eight Testing Cards, five WADE Examiner's Recording Forms AB, and five WADE Examiner's Recording Forms B. (Additional Recording Forms for AB and B can be purchased separately.).
