The Test of Aided-Communication Symbol Performance (TASP) is an augmentative and alternative communication (AAC) assessment battery designed for use by individuals with cognitive, communication, or speech disabilities. This test of symbolic skills provides a starting point for designing or selecting an appropriate page set for an AAC device. The test can also be used to help design communication boards. Results can also help in establishing appropriate AAC intervention goals and strategies targeting symbolic and syntactic development, and can be used to benchmark progress in aided communication performance. Subtests, which can be administered over a period of sessions, are included for symbol size and number, grammatical encoding, categorization and syntactic performance. Basals and ceilings are established for each subtest. The test can be administered to children or adults who have the physical ability of functional pointing. Administration time is 10 to 20 minutes, and scoring procedures are objective and rapid. Test forms are reproducible.
