The Thackray Reading Readiness Profiles are the first original British reading readiness tests to be published and are the outcome of ten years of research in the field of reading readiness with British children. The profiles consist of three group measures and one individual measure, including vocabulary and concept development, auditory discrimination, visual discrimination, and general ability. The profiles are designed to be administered in the reception class soon after the children start school for the first time. Also included are instructions for administering the profiles, for scoring them, and for interpreting the results; games and activities to foster language development, auditory discrimination, and visual discrimination; construction and standardization of the profiles; reliability and validity of the profiles; and intercorrelations of the profiles.
