Test of Semantic Reasoning (TOSR) —Extra Forms (25 forms)

The TOSR is a standardized vocabulary assessment for children and adolescents ages 7 through 17. It measures semantic reasoning—the process of learning and retrieving new words by analyzing multiple images that convey different contexts of a word’s meaning.

Unlike expressive vocabulary tests, the TOSR evaluates both breadth (the number of words known) and depth (the richness of semantic understanding for each word) without taxing expressive language skills. This makes it especially useful when assessing children with possible language or literacy deficits. Breadth is tied to early decoding skills, while depth supports later reading comprehension.
