At last! A comprehensive standardized measure of orthographic skills!
Ages: 6-0 through 17-11Testing Time: 30 to 45 minutesAdministration: Individual or group
The Test of Orthographic Competence (TOC) assesses aspects of the English writing system that are integral to proficient reading and writing. These aspects include letters, spelling, punctuation, abbreviations, and special symbols. The TOC has three age-related forms (6–7 years, 8–12 years, and 13–17 years). Normed on a national representative sample of 1,477 individuals, it yields standard scores and percentiles for both subtests and composites. Classroom teachers, special education teachers, reading specialists, school psychologists, speech pathologists, or any other professionals with some training in standardized test administration can use the TOC.
SubtestsThe TOC has nine subtests, which vary by age-level. The form for ages 6–7 years is comprised of Signs and Symbols, Grapheme Matching, Homophone Choice, and Punctuation. The form for ages 8–12 years is comprised of Homophone Choice, Punctuation, Abbreviations, Letter Choice Word Scramble, and Sight Spelling. The form for ages 13–17 years is comprised of Punctuation, Abbreviations, Letter Choice, Word Scramble, Sight Spelling, and Word Choice. A description of the subtests follows.
CompositesThe results of the subtests on each version can be combined to form an overall composite. This composite is called Orthographic Ability (OA). The results from the 8-12 and 13-18- year-old forms can be combined to create three additional orthographic composites: Conventions (CO), Spelling Accuracy (SA), and Spelling Fluency (SF).
Technical CharacteristicsThe TOC evidences a very high degree of reliability across all three types of reliability (coefficient alpha, test-retest, and scorer differences). Alphas for the composites range from .90 to .98 and from .81 to .97 for the subtests. TOC also possesses strong content-description, criterion-prediction, and construct-identification validity indicating it can be used with confidence. The Orthographic Ability Index correlates in the .70s with 10 popular measures of reading and writing.
