The TOSS-P is a receptive and expressive diagnostic test designed to assess a student’s semantic skills and it yields specific information about a student’s semantic and vocabulary abilities. 

Children with language and learning disorders often are severely hampered when facing words out of context or new words in reading passages, or when trying to determine word meaning by using context clues. The TOSS-P meets the need for a comprehensive diagnostic test of semantics. A wide range of receptive and expressive tasks, including skills in categorizing, describing, and defining (not just naming skills), means the TOSS-P will accurately assess your students’ competency with semantics. The test is built around six common themes and comprised of twenty realistic line-illustrations depicting natural, real-life scenes. Test items emphasize vocabulary that is meaningful and relevant to the experiences of young children. In this way, your student can use visual and verbal information to respond to the test as they do to respond to their environment. There are five subtests and 10 semantic and vocabulary tasks in the test. Five tasks are receptive and five are expressive. This parallel allows for analysis and comparison of verbal and nonverbal performance. The multiple question types give students ample opportunities to demonstrate the flexibility, diversity, and richness of their language. 


The scene pictures are based on the themes of Learning and Playing, Shopping, Around the House, Working at School, Eating, and Health and Fitness.

Valid and Reliable 

The TOSS-P standardization included 1,510 subjects; demographics of test subjects closely mirror the US Census data. The TOSS-P is a reliable measure, as the average reliability coefficient is .86. Additionally, there is no evidence to suggest consistent differences in performance by race/socioeconomic status at the item level.
